c.Many-to-Many Overload: In Many-to-Many Overload mode, the TC3162 EVM maps multiple local IP addresses to shared global IP addresses.

d.Many-to-Many No Overload: In Many-to-Many No Overload mode, the TC3162 EVM maps each local IP address to a unique global IP address.

￿3.10.1.1 Virtual Server

Go to Advanced Setup ->NAT-> Virtual Server to set virtual server as you need. (known as Port Mapping).

The Virtual Server is the server or server(s) behind NAT (on the LAN), for example, Web server or FTP server, that you can make visible to the outside world even though NAT makes your whole inside network appear as a single machine to the outside world. Rule Index: The Virtual server rule index for this VC. You can specify up to 10 rules. All the VCs with single IP will use the same Virtual Server rules.

Start & End port number: Enter the specific Start and End Port number you want to forward. If it is one port only, you can enter the End port number the same as Start port
