Re: squid transparent proxy still not working

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

 



Have you followed http://wiki.squid-cache.org/ConfigExamples/ and setup
the forwarding, et al, correctly?

Just so you know, I can build a proxy from a default debian install
by following one of the examples there and transparent proxying "just"
works.
