Only one firewall. The port number is correct. I went to web page for static address and got stumped. It did not specify which address to use in Internet Protocol (TCP/IP) Properties. The router gave me LAN IP,SM,DG,DNS that matched what was in Windows IP Configuration. However the router also gave internet WAN IP,DG,DNS that were different, only the SM was the same. The router model # F9K1102V1
