RE: [squid-users] WCCP doesn't seem to work

Hi

I seem to have a similar problem too. My router is redirecting packets
to the squid box but I get an error when I try to access a web page and
the entry does not come in access.log. here is a copy of my configs. I
also noticed that when I do a netstat -i -v, I get packets recived on
the gre0 interface but not transmitted. I cannot figure out what is
wrong. ip_gre.c patched version is attached. Squid version is latest RPM
provided by RH7.3 and machine is fully updated. IPchains should be
working fine because when I set the gateway of workstation to the squid
machine, the squid works well.

2048 on squid box and ip wccp debug results on your
router and browser error msg.
thanks
