Re: [squid-users] wccp problem with squid

are your clients on the same subnet as you cache engine??

This might be causing you a problem, because the cache will try to
connect to the client directly insted of from the router which is doing
NAT, because the client expects the conection from the webserver, not
from your squid box.

hope this helps..
