Another function provided by this GRT series NAT/PAT is the virtual server mapping. Specific ports on the WAN interface (e.g., WAN 1) are re-mapped to services inside the LAN. As only 69.210.1.8 (e.g., assigned to WAN 1 from ISP) is visible to the Internet, but does not actually have any services (other than NAT off course) running on GRT series, it is said to be a virtual server. For example, requests with TCP made to 69.210.1.8:80 are remapped to the server 1 on 192.168.0.2:80, other requests with UDP made to 69.210.1.8:25 are remapped to server 2 on 192.168.0.3:25. To set GRT series for the above NAT function, use:

admin# setup lan 1 attrib Virtual

admin# setup ip_share pat modify 1 interface 1 admin# setup ip_share pat modify 1 port 80

admin# setup ip_share pat modify 1 server 192.168.0.2 80 admin# setup ip_share pat modify 1 protocol TCP admin# setup ip_share pat modify 1 name httpd admin# setup ip_share pat modify 2 interface 1

admin# setup ip_share pat modify 2 port 25

admin# setup ip_share pat modify 2 server 192.168.0.3 25 admin# setup ip_share pat modify 2 protocol UDP admin# setup ip_share pat modify 2 name mail

To show the configuration, use the list command:

admin# setup ip_share pat list

Note: The maximum number of service mapping supported by GRT series is 10.
