One issue with blocking social sites like Facebook is that users can get around this by using https. Since DansGuardian bans using http, the easiest way to ban the Facebook https link is to use the bannediplist file. Here's what to do: 1. Open a terminal window.

1. My Do Not Block List

This walkthrough uses the DNSBL portion of pfBlockerNG to remove ads/advertising and more importantly, malvertising. It essentially creates a functionality similar to the pi-Hole project except it doesn’t require a separate piece of hardware. Instead, you just use your pfSense + pfBlockerNG! If you’re interested in a write-up on installing/configuring the pi-hole on Ubuntu, I have one.Please note this walkthrough is for the new devel version of pfBlockerNG. The pfBlockerNG-devel package is now in the standard list of available packages and no longer requires the development/experimental branch of pfSense firmware. Even though the package states “devel,” I have no issues using it in production.

First, I was lucky enough to be a beta tester for this release and the number of are astounding. Second, the configuration is 10X easier.

• Nov 6, 2017 - PfBlockerNG on PfSense protects your network by filtering internet traffic based on lists of. After the update most ads will stop showing however sites look actively stripped of content (which of course they are). There are a lot of blocklist providers (lists of lists to follow). 2019 Vorkbaard uit de toekomst.
• The EasyList filter lists are sets of rules originally designed for Adblock that. Fanboy's Annoyance List blocks Social Media content, in-page pop-ups and other.

Last but not least, the package is extremely stable. All that said, if you are still leery about using a “development” package on your pfSense, the older version of this walkthrough is still available at the link below.Warning: DO NOT install the latest version of pfBlockerNG unless you are on the most up-to-date version of pfSense. This is especially important if you are on a pfSense before 2.4.4. Version 2.4.4 introduced PHP 7.2 and it broke a lot of packages, not just pfBlockerNG. I would argue you should upgrade pfSense to the latest version.before. installing any new packages and the backs up my philosophy. The upgrade guide also emphasizes creating backups, rebooting before updates, etc.

Which are all fantastic advice.I love pfSense and if I could only install one package to enhance its capabilities, it is undoubtedly pfBlockerNG. It is the very first package I install after configuring a brand new pfSense and in some cases, it is the only one. PfBlockerNG is a pfSense package maintained by (on Twitter). It’s worth mentioning that BBCan177 has a where you can easily donate a few bucks to ensure he continues maintaining and adding to the package. If your using this in a production environment, I highly encourage you to donate. PfBlockerNG is an absolutely amazing package and I would argue a pfSense install is not complete without it.pfBlockerNG can add other security enhancements that I’ve discussed on this site such as blocking known bad IP addresses with blocklists (link below).

Did you add the whitelist recommendations? I am able to access Dropbox without issue. If whitelisting doesn’t work, you can also remove the offending list; simply go to the Reports - Alerts, find the feed with the Dropbox related domains, and then go back to your feeds to remove it. Don’t forget to force reload after you removing it.

You will also probably need to flush your local DNS and/or browser cache too. These items are explained in the troubleshooting/whitelisting section if you need further guidance.

Russell, thanks for the feedback! It looks like S3 was added to one of the blacklists, which in turn caused those feed downloads to fail (they are hosted at s3.amazonaws.com). Look at your DNSBL alerts (Reports - Alerts - DNSBL heading) and then whitelist one of the alerts that say s3.amazonaws.com. Go back to Update and Force/Run and you should see the download goes through without issue for those feeds. Can you verify if you used the whitelist from the guide?

I’m just curious if I need to add other hosts to it. I used the pihole for some time and fiddled with the pfsense dnsbl time and again. Before discovering that there was a -devel update to pfblockerng I tested the tld blacklist.Now you see this is extremely important and it must function like the whitelist. Download the elder scrolls v skyrim. In the older version there was a custom whitelist feature but only the tld blacklist.

That bugs me to no end. Blacklisting individual sites is extremely important. I find ad serving sites that get by the blocklists all the time (or just sites that I never want to visit). Without a site blacklist I would not use the tool.

I can’t understand why the author doesn’t provide a feature to blacklist sites on the same page or in the same area as the whitelist. It is perplexing.So I decided to search for a definition of tld blacklisting. I found someone’s answer that indicated that the tld blacklist operated like the custom whitelisting without the use of wild cards. So I tried it by putting the whole sitename in the tld blacklisting box. That worked.A few days later I saw this post and decided to upgrade.

I immediately worried that the tld blacklist feature would be broken. To my surprise it did not fail me. I did not tick the tld option on the page as you specified.So, that’s good news yet I’m fearful that since this feature is so poorly documented that he might sneak Nerf it when I’m least looking. Let’s hope not because site blacklisting here is important. And I mean “here” on this page.

I am aware of domain overrides. I don’t want to jump around to all over just to do what should be done where everything else blacklisting and whitelisting related is done. The TLD whitelist is only used in conjunction with the TLD whitelist and the author specifies this several times in the various infobox descriptions. That said, I’m a little confused about the TLD blacklist/whitelist working without the TLD option. I tested this extensively myself (and double/triple-checked as I was writing this walkthrough) and disabling TLD caused the TLD blacklist/whitelist to quit working every time.FWIW, if you want to block individual sites, you can do this without any feeds Simply go to DNSBL - DNSBL Feeds and then click Add.

You can then name it “customblacklist” (or whatever you want), leave DNSBL source blank/off, select action as unbound, and then then add your domains to the “DNSBL CustomList” at the bottom. Either way, hopefully this helps!

PfSense Web Filter – Filter HTTP(S) with SquidGuardPublished by on January 23, 2018 January 23, 2018Last Updated on 5 months agoAs the system administrator of a school, you are constantly faced with the question of how far you should filter content from the Internet. This question must be answered wherever children and young people have access to the Internet, whether in schools, clubs, libraries, at home or any other public institution. Opinions on this subject are very diverse.

There is no 100% protection. It is much more important to teach children and young people how to use the Internet responsibly. This is a very big challenge and takes time. Parents and educators are faced with this task and often do not know how best to approach it. Especially in schools, where you can’t always keep an eye on the screens, a web filter is a great help. In some countries, a web filter for schools is even required by law. But sometimes it’s just about blocking certain websites, such as Facebook, Netflix & Co.

Therefore, in this tutorial I would like to show you how to set up a pfSense web filter.No time to read this article now?Preliminary Remarksis a widely used open source firewall that. (If you need help to install, ). With the help of Squid (a proxy server) and SquidGuard (the actual web filter) we want to filter HTTP and HTTPS connections. For this tutorial we first need an active pfSense installation. The firewall.

How it worksFiltering HTTP connections is very easy and quick to set up. Since these connections are unencrypted, it is possible to examine them well and therefore block them completely or partially. Nowadays, more and more websites (even those you would like to block) use HTTPS, i. An encrypted connection between the user’s browser and the web server. Thanks to Let’s Encrypt, anyone can now set up a free certificate for their website.

This is a good thing in itself, because it increases security and makes many attacks impossible or more difficult. However, it also makes filtering for unwanted content more difficult.This “problem” can be solved in two ways: 1.

Man-in-the-middle attackOne way is a conscious man-in-the-middle attack. The proxy server decrypts the HTTPS connection and rebuilds it. This allows them to view the connection and filter it accordingly. This concept is used by most web filter solution providers. The problem here is that this profound interference with the HTTPS connection means that the actual security provided by HTTPS is no longer guaranteed.

A user can hardly recognize the difference if the certificate of the proxy server is trusted. But this security is deceptive. Even if this is the only way to speak of true content filtering, this solution is dangerous, very risky (implementation is not trival) and, depending on the country, incompatible with the prevailing laws (keyword data protection and privacy). Therefore, this route is not recommended for safety and moral reasons. URL filter via SNIAnother possibility is filtering via SNI. Before the certificate is queried between browser and web server and thus an encrypted connection is established, the browser sends the domain name (FQDN) that it wants to query.

This part is not yet encrypted and can therefore be read by a (transparent) proxy and used for filtering. The following figure illustrates the TLS handshake.You can easily see that the SNI is sent before the key exchange and the actual secure connection. We take advantage of this principle and in addition to the web filter for HTTP connections, we can also set up a URL filter for HTTPS connections without destroying HTTPS by a man-in-the-middle attack.

Safe-Search for search engines Create firewall rules for DNSSince we can’t look into an HTTPS connection, unwanted images and videos may appear in a Google search, for example. Google and other search engines therefore offer a secure mode (Safe-Search) because we want to force it.First we have to activate the DNS resolver in pfSense (under Services → DNS Resolver) and then save and apply the changes.In order for the computers in the network to use the DNS server of the firewall, we need a rule that forwards all other DNS requests to the firewall. To do this, we create a new rule under Firewall → NAT in the Port Forward tab with a click on one of the two add buttons. We enter the following:. Interface: LAN.

Protocol: TCP/UDP. Destination: Any. Destination Port Range: DNS (53). Redirect Traget IP: 127.0.0.1. Redirect Target Port: DNS (53). Description: Can be freely selectedNow we have to make sure that our newly created firewall rule is in the right place.

It must be above the default “ Default allow LAN to any rule“! To do this, we open the firewall rules under Firewall → Rules and move the rule up.

Then save with Save and Apply to apply the changes.Host Overrides for Bing and YoutubeNext, we’ll create some DNS entries to make sure that their safe search is used for both Google and Bing. To do this, we open the DNS Resolver again under Services → DNS Resolver and add the following entries in the section Host Overrides below.Bing:. Host: www. Domain: bing. Com. IP Address: 204.79.197.220. Description: Bing.

Then save with SaveThen the entry for Youtube:. Host: www. Domain: youtube.

Com. IP Address: 216.239.38.120.

Description: Youtube. Save again with SaveNow apply the changes again with Apply. Host Overrides for GoogleGoogle uses a lot of different domains and it would take quite a long time to enter them manually. That’s why we choose a different way for Google.

First, we need to log in to pfSense via SSH (or connect a screen + keyboard if the pfSense is installed on a computer with a graphics card). SSH must first be enabled in the web interface and System → Advanced in the Secure Shell section.Now we can log in with the following command via SSH (adjust IP address!). Include: / var / unbound / google. ConfOur search engines are configured.

The next step is to set up the content filter for HTTP and the URL filter for HTTPS. Squid Proxy and SquidGuard InstallationTo enable pfSense to filter the URLs, we need a proxy server through which all requests from our network are routed. For this we use Squid. As the name suggests, SquidGuard is the actual filter. Under System → Package Manager in the Available Packages tab we install Squid and SquidGuard.Setting Up Transparent Proxy for HTTPUnder Services → Squid Proxy Server we now set up the transparent proxy for HTTP. A transparent proxy has the advantage that we do not have to configure any settings on the individual computers in our network. In the General tab we activate the following items:.

Enable Squid Proxy ✔. Proxy Interface (s): LAN. Allow users on interface ✔.

Transparent HTTP Proxy ✔. Transparent Proxy Interface (s): LANAfter saving with Save we determine in the tab Local Cache how much disk space should be used for the cache (here 500MB):The settings have to be saved again with Save.

The transparent proxy for HTTP connections is now set up. Configuring SquidGuardSquidGuard is the component responsible for filtering the content. Each request is examined by SquidGuard and then decided whether or not to block the request or the website. For this we use a blacklist, which we configure later. Before that, we’ll define some general settings under Services → SquidGuard Proxy Filter. Enable ✔. (not shown in the screenshot).

Enable Log ✔. Enable log rotation ✔. Enable Blacklist ✔. Blacklist URL: we save everything again with Save.With the SquidGuard we have to keep in mind that changes in the configuration only become active after we have clicked Save and Apply (above in the General Settings tab)! Setting up blacklists and whitelistsNow that we are done with the basic settings, the blacklists and whitelists are missing. The URL for the blacklist is already given.

My Do Not Block List

Now we have to download them in the tab “ Blacklist“.In order to make sure that our filter works, we are now defining several target categories. To do so, open the tab “ Target Categories” and click on Add. We create a whitelist of all domain names we explicitly allow. That would be e. All Google domains, because we will block all other search engines in order to prevent the user from bypassing the Safe-Search feature set up above.We will enter the following:.

Name: Whitelist. Domain List. De google - directory. Ai googlepirate.

Com. Description: Whitelist.

Save with Save.The last step for the time being is to establish some rules. We do this in the Common ACL tab. Then click on the “ +” sign in “ Target Rules List” to open a list of the different rule sets. There are now different categories and our whitelist appears here. We now make the following settings:. Whitelist: access whitelist. Default access all: access allowThe other categories can be set as required.

Here are some examples:. Block advertising:blkBLadv access deny. Block pornography:blkBLporn access deny. etc.To prevent a user from bypassing our URL filter by entering the IP address of a page, we still enable Do not allow IP addresses in URL. If this setting causes problems, you should deactivate it again.Then we save with Save, switch to the General Settings tab and press Apply again to apply our changes. Test SetupEverything is set up for HTTP connections and we can test the setup. Nothing else needs to be set up on a computer in the LAN.

The filter should already work. If we visit a page that appears in one of our blacklists, this page will appear:Transparent proxy for HTTPS connectionsUp to now, the transparent proxy is only active for HTTP, i. Unencrypted requests.

At the beginning of this article I already pointed out the difficulties in filtering encrypted, i. HTTPS connections.

In our case, we will activate a transparent proxy for HTTPS, which allows us to enable a URL filter for all requests on port 443 (HTTPS), but with the disadvantage that we cannot (and don’t want to!) analyze the content and we can’t do a nice error page. Instead, the browser will display a certificate error message.

But more on this soon.First we activate the transparent proxy for HTTPS. To do this, open the proxy settings under Services → Squid Proxy Server and select the following settings in the SSL Man in the Middle Filtering section:. HTTPS / SSL Interception ✔. SSL/MITM Method: Splice All. SSL Intercept Interfaces: LAN.

CA: Select a Certificate Authority Certificate. Maybe we’ll have to create one first. (under System → Cert. Manager). Save all with Save.Now everything is set up and we can also test HTTPS connections. As already written, this time we don’t get an informative error message like for HTTP connections, but a warning from the browser:Even though this error message is not very meaningful, we have achieved our real goal of blocking unwanted pages.

ConclusionWe have now set up a system that filters all network traffic in our LAN (or WLAN). This blocks pages that have been defined using the blacklists.The pros and cons of such locks have different positions. In any case, it is a problem that cannot and should not be solved 100% technically, since it is rather a question of educating (young) people to be able to deal responsibly with the medium “Internet”. It is certainly not the right way to achieve this goal by means of such filtering alone. The fact that children and young people are “accustomed” to censorship and filtering is also viewed critically by some.On the other hand, it is especially helpful for schools, libraries or at home if you can limit the amount of non-appropiate content.

Some countries also prescribe such a filter by law!(Source: ). Adam May 14, 2018 at 9:28 pmMuch like Seth, all https traffic appears to be blocked in this configuration for me as well. I have my sites whitelisted but to no avail in https. It works fine with http though. Any ideas?With that being said, My state’s laws says schools MUST filter traffic in schools. Furthermore, the school owns all traffic in the network as it is guided by a legal AUP. I am not sure how other states do this but it is legal to do the conscious MIM attack for our purposes.

I do side where conscious MIM attacks could be a security breach, keeping kids safe is also an important role as well. My school already has a commercial system that does this in fact. While I am not trying to open a debate on this at all, I am merely trying to lockdown my students internet during testing times to curb the possibility of cheating. We use Cisco Netacad for this which is on amazon AWS. There are many URL’s and writing a simple router ACL would be a pain due to the complexity of our setup. Any input/guides on the Conscious MIM setup?
