Squid3 squidGuard works only on some inferfaces

  • Hi

    I've installed squid3 and squidGuard on a fresh installation of PfSense 2.2.2

    I'm using trasparent HTTP proxy.

    On first interface (my internal Lan) proxy works perfectly !
    On second interface (one of my WiFi net) proxy works perfectly !
    On third interface (another WiFi net) I cannot useĀ  proxy in Trasparent mode but it works perfecly if used in explicit mode !

    Can you help me to debug problem ?! Or can you suggest me an correct approach to isolate and solve problem ??!
