Guide to filtering web content (http and https) with pfsense 2.3

[marksantos]

Hi sir, all step are follow, search engine n safe search is working, but some of the images in whitelist website can't load.

[aGeekhere]

Just tested and it loads fine for me. Check your blocklist in your web filter (e.g squidguard).

[marksantos]

the problem is default acl. when i try do deny all, the whitelist website can't load some images, when i try to allow default acl the whitelist website, can load images but the browsing of the whitelist are very slow.

[marksantos]

i'll try the whitelist website can only access and the other can block.

[marksantos]

hi sir, how about gmail, how to allow gmail in whitelist, i tried add gmail.com in whitelist but still block the access.

[aGeekhere]

In squidguard set Default access [all] to allow. Now only block the categories you want. You can use shallalist for categories.

dns resolver doesn't start when i include the forcegoogle.conf in the custom options.

if i remove it, it works just fine.

[aGeekhere]

did you make the forecegoogle.conf file?

[4o4rh]

@aGeekhere problem was, i followed the initial instructions by putting the youtube and bing into the host overrides, then copied the whole forcegoogle section without checking the contents.

In has youtube with a different address and bing. Removed those and it works.

i have follow the topic to do the filter but when i just activate transparent mode only i get this message " 400 Bad Request
The plain HTTP request was sent to HTTPS port
nginx"

May i know what happen for this ?

[aGeekhere]

only using the transparent can cause connection issues, in this guide i have it as a fallback for programs which do not have proxy settings.

First setup WPAD or manually configure devices to use proxy
then configure windows to auto use the proxy in lan settings
then set up the transparent proxy with mitm splace all to catch programs with no proxy settings

@aGeekhere

1. But at firewall rules already forward all Lan to proxy still need to setup WPAD ?
2. At proxy settings i have Enable Transparent Proxy Settings & SSL Man In the Middle Filtering by spice all.
3. Because i have filter social network and shopping and youtube website.

@johnchon said in Guide to filtering web content (http and https) with pfsense 2.3:

But at firewall rules already forward all Lan to proxy still need to setup WPAD ?

When you only use Transparent you can get connection issues. Try this, configure your device to use the proxy,for windows it is under lan settings (WPAD automates this).

Next make sure your web browser is using the proxy.

Do you still get connection issues?

[johnchon]

@aGeekhere i have both enable tranparent and the SSL filter, when only enable using transparent mode only all website running good. No issues for connection. i'm using firefox for auto detect proxy server.

[johnchon]

@aGeekhere when using manual for firefox proxy IP:192.168.0.1 and port :3128 , then the connection issues

[aGeekhere]

for firefox there is a bug where if you set it to use system proxy settings it will not connect https://bugzilla.mozilla.org/show_bug.cgi?id=621429

manually configure firefox to use the proxy

[johnchon]

@aGeekhere i have set to use manual for IP 192.168.0.1 and port :3128, and tick use this proxy for all protocol but the connection issues also.

@aGeekhere I know this is an old topic and all, but I just wanted to express my deepest gratitude to you ageekhere, I have been struggling with squid, pfsense, and trying to get crap to just freaking work for a few weeks to a month now, I am FAR from the most knowledgeable or experienced in this crap, but this is what I'm passionate about as a hobby of mine (hopefully career in the not so far off span of time) and all of my knowledge is self taught, trial and error, a handful of catastrophes (NOTE A POWER SUPPLY SHOULD NEVER, EVER, SOUND LIKE AN ARC WELDER, IF IT DOES, YOU JUST NUKED IT, TAKE MY WORD FOR THIS ONE XD) and a LOT of hard earned money spend in this hobby of mine, to the degree you'd think illicit substances would be cost saving!!! jokes aside though (seriously, bad joke, but I can't help myself because I spend so much money on this hobby its sickening/nauseating to think about!) I do this stuff for fun, and out of all the guides I have followed so far, yours has a HANDFUL of points that I had missed in my attempts to set up wpad/squid/all of this stuff, and so far so good, so I just wanted to pop on here, resurrect an old thread, and say THANK YOU!

[aGeekhere]

I still run this setup and everything is working fine, a lot of trial and error went into getting this to work.
Cloudflare's new 1.1.1.2 and 1.1.1.3 is a new thing that can be added to this setup
https://community.cloudflare.com/t/pfsense-and-1-1-1-3-not-blocking-adult-content/164747/10
they are still working on DoT for 1.1.1.3.
