C7000V2 - portforwarding two xbox consoles - HELP

[SpookyBooty]

Hello!

I just purchased a new cable modem router to get rid of the one we were renting from Spectrum. It's all set up and running great except I'm having trouble portforwarding my two consoles as all the how-to articles aren't going in dept enough for my model. If anyone cuould help that would be AMAZING. Thank you in advance! I have my console connected and working just fine but my husband's console is my problem console.

How are you connecting the xboxes to the modem? Wired is preferred. 

Port Fowarding shouldn't be needed. Only enable uPnP is needed. 

You can check to see if you have a feature call NAT Filter in the modems UI. Maybe under Advanced Setup/Internet or WAN setup.
