Could this be working? PfSense on the same subnet - Transparent Proxy



  • All these numbers are here for the exemple.

    INTERNET –-- Router 10.10.10.201
                          |
                          |
                        Switch -------- Users (10.10.10.X)
                        |
                        |-- PfSense WAN : 10.10.10.50
                        |-- PfSense LAN : 10.10.10.55

    Hello, I was wondering if this could work, if the WAN and the LAN could be plugged on the same switch with other PC.

    Basically, if PfSense could work with his two network card connected on the same subnet.

    I need a proxy transparent here and I'm lost (i'm not a professional.. yet, so pardon me my stupid question, call me an idiot if you want but please, explain me).

    Thanks by advance.

    No, you can't have WAN and LAN on the same network.

    pfSense must be the router for transparent mode to work.  You could setup pfSense with just a LAN NIC and then use WPAD to allow your clients to discover the proxy on their own.



  • With just a LAN nic?

    Sorry I don't understand this part.

    I tried this afternoon to configure pfSense with only the WAN configured, and my only problem was : I can't install package (here, squid).

    I access the webconfigurator with the WAN IP but squid don't wanted to be installed (I wanted to follow this HOWTO : https://forum.pfsense.org/index.php?topic=46351.0)

    So yeah, I'm stuck :/



  • Why do you want to specifically use pfSense here when all you seem to need is a proxy server?  Any *BSD or *nix box could do that for you.

    I've never heard of a single-NIC config where the NIC is WAN.  I also haven't had the need to actually configure like this, so I don't have direct experience.
