and in [ IP Ethernet 0.1 ]:
SubnetMask = 255.255.0.0
IPAddress = 10.5.0.1
Notes: All workstations on the LAN directly connected to the Internal NAT Port must have
this IP Port's address (10.5.0.1, in this example) set as their Gateway route in their IP
applications.

NatMap = Off
As for the External and Internal NAT Ports, the router must be configured, or have the ability,
to route the IP traffic addressed to and from the NAT PassThru Range. Also, the NatMap
variable for this IP sub−interface is set to Off (the default value).
