G'day, I have this NAT/firewall box (debian) configured with iptables. Port forwarding etc works fine for one exception: A need a rule that 'echoes' back udp packets if they meet the following criteria: + in-interface=eth1 (that's the 'private' interface) + destination IP is public ip-address (e.g. 1.2.3.4) (that's eth0) + Port range is e.g. 30000-32000 + The packets need to be forwarded via eth0 (thus echoed) to e.g. 10.10.1.2, same port. Hope you can help me and thanks in advance! Martin.
