How do you add a port to port forwarding?

[robcampbell]

I've been trying to add a port to my port forward since I've had this thing in June and I haven't been able to get any assistance from Xfinity on the issue.

Please try again. If the problem persists, check back later.

It never works.

Connect->See Network->More/Advanced Settings->Port Forwarding

[EG]

Try disabling the Xfi Advanced Security feature as a work-around for now and see. It's buggy ! And there is currently no way for an end-user to be able to whitelist anything;

Thanks but that didn't help.  Still getting the same error and reaching anyone at Xfinity that can help is impossible.
