port forwarding on newer routers does not work

Still running a 5-year-old Comcast business router. It has full support for NAT, including the ability to map the incoming port to an outgoing port for example:<WAN IP>:22 to <LAN IP>:2222 such as:100.100.100.100:22 to 10.0.0.5:2222 This port remapping is
