Transparent Squid proxy error - not-transparent is working

  • Hi there,

    I recently installed pfSense 2.0 RC3 on a box as a MultiWAN-Router (WAN1 PPPoE 25Mbit down/5Mbit up dynamic IP, WAN2 PPPoE 16Mbit down/1Mbit up static IP). Everything run's fine. Even if I configure a webbrowser on a client to use the Squid on the pfSense box directly. But if I enable the transparent mode, clients get this error message:

    The requested URL could not be retrieved
    While trying to process the request:

    The following error was encountered:

    Actually, I must say that I don't have an idea so far. Proxy-"Additions" like HAVP and / or Squidguard don't have an impact on that problem, so regardless if those modules are installed and / or configured, the problem resides.

    Thanks for any help in advance.

    Running Squid with multiwan is a special case. Have you read this:


  • Hi Steve,

    thanks for that hint. I didn't see this before. I'll give it a try. Great, thanks.
