Port Forwarding 360 problem

[JK-47]

I'm port forwarding my router to my Xbox 360. I entered the information in my Virtual Servers accordingly, but when I try to apply the changes, an error box pops up and says:

"Public port number can not be 88 because it will have collision with the wireless router web service".

Here's the settings I typed in:



Edit:

Nevermind, I figured it out. For anyone who has this problem, I'll just post what I did.

I just enabled my UPNP, then rather than setting both inbound ports and private ports to 88-88, I set them to 87-89.
