I have a dd-wrt router which I want to use for traffic redirection. In my case I have a VPS with Oracle which is listening on port 1521. I would like to access this server from my work but unfortunately port 1521 is blocked. I would like to use Oracle on port 25 from my work so I'm looking for a way to redirect traffic using my home router. So I need to configure the router to receive traffic from my laptop on port 25 and redirect this traffic to port 1521. Can you tell me what is the correct way to configure the iptables for this case?
