Unofficial E2guardian package for pfSense

Create a file on filesystem with the script and then call the file on cron.

@Marcelloc, I have a NAT rule to redirect port 80 to my pfsense box IP and port 8080. Should I do the same for 443? Or will that completely break it? I don't mind being having to install the certificate, but is there a way to just force all the traffic through E2Guardian. In some cases, such as Android, it seems other methods such as WPAD etc, don't work.

That rule will brake wpad retrival. Did you add that before testing Androids?

Hmm how can I get that setup with WPAD still working? Somehow WPAD seems to be working. My pc is set to automatically detect proxy settings and it does, however it didn't work on IOS maybe this is it.

I tested with this rule on android, works for http traffic. It'll successfully go to the block page if the website isn't allowed.

Create the rule and try to fetch the wpad file. If it fetches, the is no conflict.

Able to fetch it no problems, as long as I type http, since web config is on https.

Didn't work at first, but added "Done" at the end of the script. Now it seems to be working fine.

Bad copy and paste. Sorry. I've fixed the post

Can you test if a full MITM e2guardian setup with no exceptions crashes? current binaries from package are not on the latest version but it's close to it. If you can confirm a crash, I'LL build with current latest code.

I found an workaround util 4.1.1 gets fixed 8)

Configure squid to intercept SSL connections with splice all mode (this checks only remote certificate)
Configure e2guardian Parent proxy Settings with your squid ssl interface configured.

Testing with steps I know that crashes the daemon but it's still alive with and without MITM.

Won't squid and E2Guardian conflict with each other if I configure squid to intercept traffic? Since it creates a NAT rule and I already have a NAT rule for port 80 > 8080 for E2guardian.
Remember squid is completely unrestricted in terms of allowing Web access without E2 Guardian. I also realised you updated the package, what's new in the newer version?

Got the error below on the latest version available in the repo.

Did you tried the debug version package I've posted before?

There is a new config option (banner site with bypass key) on new binaries, you need to save config and apply in order to get correct config files.

I updated via the console, and it might have automatically gone to the debug version. Where is that option? :o

marcelloc · Jun 11, 2017, 11:13 AM

No, debug version needs a manual intervention.
To be sure you're not on a debug version, just try to run run /usr/local/sbin/e2guardian on console

When I run the command I am getting an output. Does that mean I'm on the debug version? I'm confused.

big output with a lot of information means debug mode, if it backs to console then you're on normal version.

marcelloc · Jun 11, 2017, 11:52 AM

Try to delete the crash alert and see if it happens again. I have no alerts or crashes on gui here.

Yep I am getting a lot of information. I ended up on the debug version just by updating through the console, how do I return back to normal version? Or do you recommend I stay on the debug version for now.

marcelloc · Jun 11, 2017, 12:34 PM

Uninstall then Install the package using the gui. And see if it will install the debug version.

Yep, after re-installation running "/usr/local/sbin/e2guardian" again I'm still getting back a lot of information.

EDIT: got the error again

I'll remove the debug version from repo. Are you on 2.3 amd64?

EDIT

done. No debug version on repo. An uninstall and reinstall should fix.
