extracted from the IP address in the LAN Configuration setting.

n = 1 to 10 port forwarding number

eeeee = 0 to 65535 external port number to forward to

lllll = 0 to 65535 local port number to forward to

t = 0 disable

t = 1 UDP

t = 2 TCP

t = 3 both UDP and TCP

The current port forward settings can be queried by using firewall without parameters.

Note that LAN IP addresses used in port forwarding rules must match the LAN subnet as configured using

lanip, lannetmask, and lanrepip.
