Yeah, the gaming software does say it has problems with firewalls
in routers.


"That gaming software must not work so well through the firewall built into those routers. I would check into the documentation for that software and see if they have and How-to's for setting it up with a firewall. You will most likely need to setup port forwarding to get it to work through the firewall. Port forwarding is a much better solution that exposing yourself direcltly to the open internet."

Yeah, but if I turn my routers firewall off, and leave my computer firewall on, will I still be protected? What I am asking is, can I deal without the routers firewall?
