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) ->
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
Well, hosts A and B can ping/telnet eachother, but port redirect does not
iptables -t nat -A PREROUTING -p udp --dport 6000 -j REDIRECT --to-port 7000
Well, noting happens... packets traverse firewall/gw without any
The same thing works flawlessly with tcp protocol (-p tcp, running tcp
listening server on port 7000)...
What am i doing wrong?
