NAT: Network Address Translation (NAT) on the WAN interface of the Vanguard 3G unit.
When NAT is enabled, the LAN (Ethernet) is considered private, the WAN is considered public.
Any IP packets leaving the Vanguard 3G unit through the WAN interface will have its source
IP address changed to that of the WAN interface.
Port Forwarding: Enable - The Vanguard 3G unit performs port forwarding. The "IP Mapping
Table" contains the rules used to perform port forwarding.
Disable - The Vanguard 3G unit does not perform port forwarding on the WAN interface.
Mapping Number: User selected generic number assigned for this route.
Protocol: TCP, UDP, or both - driven by the protocol used by the third party device
Source IP Address: Enter the IP address of the remote PC connecting to the third party
device. (This should only be done if a single PC with a STATIC IP is accessing the device and
you want to limit access to the device.) If you will be accessing the third party device from
multiple PCs, or from a PC that has a dynamically assigned WAN IP, enter 0.0.0.0 (wildcard)
to allow all remote PCs to access the third party device.
