Hello,
i'm trying to get squid and wccp on a cisco asa 5510 running. These are
the steps, i've done to set it up.
#aptitude install squid3
#vi /etc/squid3/squid.conf

The asa detects the proxy and redirects the packets. On the
squid-machine, i can see the syn-packets from the client, but no
ack-packets.
The counter for the iptables-rule is also increasing. If i remove the
iptables-rule, the clients can browse the web, because the squid-machine
is acting as a router, so the gre-tunnel seems to work correctly.
After some research, i've found out, that the ack-packets are send out
at eth0. I don't think, it's the correct way.
Are there any things, i've forgotten? All howto's i've found, don't tell
me any other steps.
System is Debian lenny with squid 3.0.STABLE8-3.
Is there anyone, who can give me a hint?
Thanks,
Tom
