Hello guys, I'm becoming crazy! I am a student and I am working with Squid for a project about content delivery networks. Setting up the system (all in IPv6) I have found out some issues. To set up it I followed http://wiki.squid-cache.org/Features/Tproxy4 because I need a trasparent proxy and for IPv6 this the way. The problem is that passing through I have to start a rewrite_url_program, written in perl. All is working, I pass, the perl file is started and so on. But I have to rewrite the url or to a machine called origin or to the local machine, where I have installed Squid. If I rewrite the url to go to the origin, is ok. When I rewrite the link to go to the local cache it seems like blocked. I am using this iptables rules: ip6tables -t mangle -N DIVERT ip6tables -t mangle -A DIVERT -j MARK --set-mark 1 ip6tables -t mangle -A DIVERT -j ACCEPT ip6tables -t mangle -A PREROUTING -p tcp -m socket -j DIVERT ip6tables -t mangle -A PREROUTING -p tcp --dport 80 -j TPROXY --tproxy-mark 0x1/0x1 --on-port 3129 and I set up also ip -f inet6 rule add fwmark 1 lookup 100 ip -f inet6 route add local default dev eth0 table 100 <= changed dev with arriving interface (for me eth2) It seems that the packets redirected to the cache of the machine with squid are in an internal loop. Can you help me to understand why, and maybe how to find a solution? This mechanism was working with the IPv4 rules for the trasparent proxy (with nat chain), but here with IPv6 the things are different!!!
