WAN and LAN on the same subnet for transparent proxy?

zeb50

Hello,
quick question here, I was wondering if I can setup a PfSense like this, so he can work as a transparent proxy :

WAN : 192.x.x.74/24
LAN : 192.x.x.75/24

I think it's not possible, but I'm starting here, and I search how to add a transparent proxy for me.

Thanks by advance

Do you really want a transparent proxy or a filtering bridge?

Derelict

You mean something like this?

Yes, a transparent proxy @jahonix :)

I want to keep logs from where users are going but without modifying there PC, so transparent proxy.

And @Derelict, thank you but this isn't what I meant, I know how to install Squid on PfSense but I'm not PfSense will accept the configuration I wrote in the first post :

WAN : 192.168.1.74/24
LAN : 192.168.1.75/24

I suppose if PfSense accept this, he will accept Squid either, but that's the point, will he accept that? :)

Asking such questions means you don't understand how Ethernet works.
Sorry.

You cannot have WAN and LAN on the same subnet, no.

Which has nothing to do with how a transparent proxy works anyway..

Well, I was pretty much sure I wouldn't be able to do that, but I was searching a confirmation.
Sorry for the silly question and thanks @doktornotor for the answer!
