Reads like two NAT routers in the data path - the Xfinity modem (also a router typically), and the Netgear router.
A little bit tricky doing the set-up and the port forwarding properly. First you have to ensure the Xfinity does always issue the same WAN/Internet IP to the Netgear router, then do the port forwarding on the Xfinity to the Netgear WAN/Internet IP, and now also the game system on the LAN (which has to be on the same LAN IP always), and then forward the port on the Netgear to that LAN IP.
