RE: Really transparent proxy

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Zul, we already do that... it doesn't chance anything :(

I don't remember right now how it was but, in option 1 via off, forward off, show that I'm BEHIND a proxy, but show the client ip address. Option 2: Without via and forward doesn't, but shows the squid ip address, instead the clients ip, I don't know if you understand me :(

But it was something like that :(

Tnxs to all

Have you turn OFF "via" and "forwarded_for" on your
squid.conf?
