NAT Squid 3.0 Issue ?

[Helium75]

Hello Community,

after a buisy weekend I discovered that there was an update to the pfSense firewall.
So I decided to click it … I guess that was the worst decission ever ... might have worked on a Tuesday, but never do that Mondays.
Anyhow.

The setup:

• Squid 3.x as transpartent proxy , using the standart port on the LAN interface.
• LAN is clicked on the transpartent setting part
• Lan is also activated for general interfaces ( top part)
• no additional ACLs added
• no additional settings

The result :
Squid stopped working after 2 minutes. So I was trying to investigate what caused that mess.

What I did so far :

• reinstalled squid ( same result , no internet access)
• upgraded squid from version 2 to version 3, no change
• downgraded to the prior version of pfsense ( very bad idea, cost my 2 hours of me life to fix it afterwards and re-roll to 2.2)
• checked all log files. No result, nothing there that shouldn't be there

What I found out:

• When you access squid on the designated server port (3125)  - it works.
• When I take the settings of my browser off ( direct internet access ) - no connection

My question :

• Does Squid set up a NAT rules for the server ? If so, would I see that on the NAT GUI ?

I hope the section I opened the thread is the correct one, wasnt qutie sure where to put it.

Thank you very much for any idea how I can fix this issue in advance.

Best Regards
Andi
