Block Inbound IP Traffic From Wireless Network – If set to Yes the router’s firewall is configured to block any inbound
originated (but not response) packets from the wireless network (WAN). This firewall is then selectively modified by the
forwarding entries defined through this screen. If this parameter is set to No, the router’s firewall is disabled.

Use NAT on all Ethernet traffic to wireless network – For normal operation this parameter should be set to “Yes”. In
some unique situations, you may connect the router to a network where you will be given public address to use on your
LAN’s Ethernet segment. In such cases, NAT should be turned off. NAT is currently required for operation on all US
networks such as T-Mobile USA or AT&T. Typical environments where NAT would be turned off would be private
networks or some types of VPNs and in these cases, the network operator will most likely provide configuration
assistance.

Forward Inbound Port – This table allows WAN side packets addressed for specific IP ports to be routed to a specified
address on the LAN side.

Of Local Address – Used to specify the LAN side address of the routing operation.

TCP – Route TCP/IP traffic
