Hi, I'm trying to redirect all IPv6 traffic entering eth0 on port 80 to a locally running proxy server. But for some reason, the remote client gets only a connection timeout. I do see traffic entering eth0 to port 80, but nothing happens. This is what I did : ip -f inet6 rule add fwmark 1 lookup 100 ip -f inet6 route add local ::/0 dev lo table 100 ip6tables -t mangle -N DIVERT ip6tables -t mangle -A PREROUTING -p tcpo -m socket -j DIVERT ip6tables -t mangle -A DIVERT -j MARK --set-xmark 0x1/0xffffffff ip6tables -t mangle -A DIVERT -j ACCEPT ip6tables -t mangle -A PREROUTING -p tcp --dport 80 -j TPROXY --tproxy-mark 0x1/0x1 --on-port 3128 Any ideas why it doesn't actually connect to port 3128 ? I tried using --on-ip as well, but no difference. Thanks for any help ! Wim
