Re: [squid-users] squid and wccp

I am trying to configure squid wccp and cisco router but with no luck.
This is what I have done. Please check my procedure and confoguration:

for squid version 2.6Stable19 running on Fedora Core 8 64 bit with ip address xx.xx.184.178
1. I configure squid with options enable-linux-netfilter

2. in squid.conf
    http_port 8080 transparent
    wccp2_router xx.xx.184.177
    wccp2_version 4
    wccp2_forwarding_method 1
    wccp2_return_method 1
    wccp2_service standard 0
    wccp2_address 0.0.0.0

3. modprobe ip_gre
   ip tunnel add wccp0 mode gre remote xx.xx.184.177 local xx.xx.184.178 dev eth1
   ip addr add xx.xx.184.178/32 dev wccp0
   ip link set wccp0 up

4.echo 0 >/proc/sys/net/ipv4/conf/wccp0/rp_filter

5.iptables -t nat -A PREROUTING -p tcp -i wccp0 -j REDIRECT --to-ports 8080

6. iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-ports 8080

On Cisco router7206 npe300 with 12.2(31)

ip wccp version 2
ip wccp web-cache

It seems everything is working fine but configuring client browser without any proxy it is not browsing. note that if I manually define the Ip address of the transparent proxy I can browse the web.

Can anybody help me on my problem?

thank you very much,
Wennie

Just ip_gre. the GRE code shipped in linux these days includes WCCPv2 packet
decoding.
