Redirect connection to a port to another port

I have an application listening on a specific port. The port that the application listens is allowed on my home network but is sometimes blocked on other networks. I would like to have a backup port that I can use to connect back home. I will connect to the backup port and have the traffic redirected to the main port.
How would I redirect incoming traffic on the backup port to the main port?
Edit:
I tried iptables -t nat -A PREROUTING -p tcp --dport [incoming port] -j REDIRECT --to-port [main port]. Do I have to restart my machine for the changes to take?

You may want to do this on your home router. Your router can listen to the incoming port and port forward it to the standard port. This has nothing to do with Ubuntu.

That's a good idea.
