Hi,
I need to setup wccp2 between my Squid3 box and my cisco switch 4507
Since my 4507 don't support GRE on forward methoding I need to configure the the wccp with L2.
My squid.conf
http_port 3129 intercept
wccp2_router $IP-OF-ROUTER
wccp2_forwarding_method l2
wccp2_return_method l2
My question is, in GRE method I need to create a GRE tunnel like this
modprobe ip_gre
ip tunnel add wccp0 mode gre remote $ASA-EXT-IP local $SQUID-IP dev eth0
ifconfig wccp0 $SQUID-IP netmask 255.255.255.255 up
echo 0 >/proc/sys/net/ipv4/conf/wccp0/rp_filter
echo 0 >/proc/sys/net/ipv4/conf/eth0/rp_filter
echo 1 >/proc/sys/net/ipv4/ip_forward
iptables -t nat -A PREROUTING -i wccp0 -p tcp --dport 80 -j REDIRECT --to-port 3129
iptables -t nat -A POSTROUTING -j MASQUERADE
In L2 method the configuration is the same (tunnel, sysctl, iptables..) ? if not can you help me to configure it (tunnel, sysctl, iptables..).
Also in switch what's ACL I need to create?
Best regard
