Hi! I want to redirect packets incoming on eth0 on port 12345 to port 12346 on the same machine. Already got it working with this command: iptables -t nat -A PREROUTING -i eth0 -p tcp --src 1.2.3.4 --dport 12345 -j REDIRECT --to-ports 12346 Client 1.2.3.4 can connect to 12345, but is logical connected to service on 12346. But I want this for all sources, so I omitted the src-param. iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 12345 -j REDIRECT --to-ports 12346 This way the client can't connect to the service. Could someone explain me this behavior, please? I am forwarding both ports with my home-router (Fritz!Box) to the machine, I also tried to forward the external port 12345 to the local machine:12346, but this also does not work. Could the service causing the problem?
