Have you tried running it without port forwarding? This could actually be causing some of your weirdness, as when you forward ports you are forwarding them to a single IP address. That may have been what they were hinting at, but just didn't explain it properly.

Not once have I needed to port forward for a game. The ONLY time I forward is for something very specific like remote desktop access from work--but never to make a game behave. It's always been managed just fine through my router's NAT--and that's on 3 different brand names to date since 1996: a Blitzz, Belkin, and my current Netgear. Not high dollar ones either--these have been locally bought Wal-Mart items... and I've NEVER paid more than $40 for a router.

NAT has come a long way in recent years, and you may find you don't actually need to forward your ports--that's often more something to use to rule out localized routing/security issues (like to punch through firewalls and such). I never needed it in XI, nor XIV, nor any online games going back to 1996 when I was in the first public test market for TWC Cable Internet for our city. And we have a lot of devices that can be on my network, and any number of them can be active at any given time for various content (cut the cable channels out, so we stream a lot on top of gaming on multiple devices at the same time), and the only problems we've run into is if we are streaming too much at one time.

Might want to give it a shot without the port forwarding, just to see. Provided you are getting full pass-through from your modem to your router, it should work just fine. You may need to tweak some security options in the WAN sections or something if you've got the full-on firewall going or something (SPI firewall, NAT Filters, SIP Algorythm, etc.)... but otherwise you may find it works fine with the default security settings.
