Hello there. I have strange udp port redirection problem. Here is my setup: A (192.168.221.101) -> (192.168.221.100) GW (192.168.222.100) -> (192.168.222.101) B I would like to redirect packet when A would sends udp packet to 192.168.222.101 port 6000 to 192.168.221.100 port 7000 where runs udp proxy server. Well, hosts A and B can ping/telnet eachother, but port redirect does not work: iptables -t nat -A PREROUTING -p udp --dport 6000 -j REDIRECT --to-port 7000 Well, noting happens... packets traverse firewall/gw without any redirection... Why? The same thing works flawlessly with tcp protocol (-p tcp, running tcp listening server on port 7000)... What am i doing wrong? Brane
