Unofficial E2guardian package for pfSense

For novice users, there is no guide on how to configure this E2Guardian for Http and Https web filtering.
As I read, E2Guardian is forked from Dansguardian but still novice users may know nothing about Dansguardian as well.
We hope that the is a detailed step by step guide on installation and configuration for http and https web filtering.
Like for me, I am creating a group on Group Tab but I dont know what ip address belongs to this group because I dont see where to set that up.
I explained in your thread the two ways you can filter HTTPS, and I explained how the group system works. The group system is used to actually identify users and group their access permissions together. For example, in a school one group could be students, another could be teachers.
There's plenty of documentation on Dansguardian which is pretty much the same thing, I know it can be a little overwhelming at first. But you need to play around with it to understand how it works. Essentially, phraselists are used to detect words and phrases within websites, URL lists are used to block URL's based on categories, site lists can be used to block certain URL's.
You then need to pick a way to identify users, one of the more simple ways is to assign devices static IP's, and then setup identification based on IP's. You then need to assign those IP's to whatever group you want, and set up the ACL's for the groups.
Here's the Dansguardian Wiki: http://contentfilter.futuragts.com/wiki/doku.php?id=faq. The actual method of how it works is pretty much the same, so the info on there applies to E2Guardian too. I can give you pointers and help towards setting everything up a bit, but I can't go through even the networking side such as setting up static IP's when there are so many great guides already out there.

what about the wpad you mentioned that is part of e2guardian package. where can i find it?
-
Pfsensation:
Where do you set the exclusions? At exceptionsitelist?
Have you tried using Logmein through the proxy? -
another thing, how do you disallow using ip address in the browser like done in squid.

Have you tried using Logmein through the proxy?Yeah, its under the sites list tab under exceptions. That's where you can throw in all the domain names. It's paramount we start creating a small list of exceptions. I don't want E2Guardian to become something which causes more problems down the line than benefits.

If you've installed the unofficial repository, via the instructions in the OP. Just go to the package manager and search for it.

I'm not 100% sure but I believe that it maybe blocked by default. I just tried going to "http://8.8.8.8" and it gave me a 504 gateway timeout instead. I don't even see how using the IP would make a different when you use E2Guardian. E2Guardian is designed in a way in which it can scan websites on the fly, whether you connect to them via IP or domain. This is the biggest reasons why I recommend it over any other kind of filtering system, because it doesn't just rely on the website link, it can scan the contents of the page too!
-
Ah nope. It should not block by default browsing by ip address because some programs here in us uses ip address, therefore, i should be able to allow it or disable it.
The OP gave two ways to install, thru package and installing using commandline, which one is it.

Have you used logmein behind the e2g using mitm?

Have you used logmein behind the e2g using mitm?
Nope, however I have used TeamViewer etc, no issues. If you have problems with logmein, just add it to the exceptions.
@Marcelloc, which one is the correct E2Guardian config that we use now? I see a tonne of them in "/usr/local/etc/e2guardian"
I'm asking because FredB, over at GitHub recons that the blacklist categories not showing maybe due to not having the following :
# List categorisation #listcategory: "Banned Sites"Check it here: https://github.com/e2guardian/e2guardian/issues/244

Next week I am going to test with version 4. With v3 I add it to the exceptions but Logmein did not work. Teamviewer did worked. It seems some apps are more strict with MITM.

All of them. E2guardian.conf is the main conf and there is a fx.conf for each group conf

Sure they are. Some like skype are not http.

Use pfSense packet capture under diagnostics in order to log where the traffic is trying to connect to, then use that info in order to add exceptions to it being MITM'd.

Could you test out getting the blocked categories to work with ShallaList? Based on what Fred suggested on GitHub.

That is an idea.
What I do is set the Device to connect directly to Squid instead of going through E2g, then I look the Real Time log of Squid to see the sites that are needed by the connection. Then I can add those sites to the E2g exceptions, and return the Device to the normal connection through E2g.
But Logmein is really strict with MITM and for some reason adding the sites to the exceptions on v3 was not enough. The sites are connected but then are dropped. It seems that having the sites in the exceptionsitelist still are processed for MITM then the sites get the forged SSL certificate which the App does not like.
If I could find a way to say to the E2g to use MITM by default on most sites and not use it for some specific sites then those strict sites or Apps will not break.

Did you tried to add this site on exceptionsitelist?

pkg 0.4.2 is almost done too with realtime tab.

The squidanalyser, provide the information like that?
SARG could do it except the reason.

The log is showing the data from access.log?
In what format? Dans format os squid format or squid extended format or other? -
The log is showing the data from access.log?
yes. original e2guardian format. If you want to see or grep the log, it's in /var/log/e2guardian/access.log
