question: what do I put in the "target port" fields when setting up port triggering?

Hello, play on a shared home connection with the wifey.
Been having some connection issues after character login screen or world loading screens, I'm guessing because of port forwarding?
Trying to set up port triggering, since we are on a shared home WiFi.
I set up the port triggering fields 9000-9058 for service type TCP / UDP, but it requires that I also have entry for "target port" (can't keep at default '0').
Does it matter what I put here?
Thanks for the help! We love DDO. It's been frustrating not being able to log on and complete a quest since the last update.

Happy Hunting ~

side note: not a firewall issue. still have connection issues after disabling firewall.
