Virtual Server
To customize inbound port mapping of NAT for a
Single User Account using one global IP address,
select the Single option under Number of IPs and
click the Virtual Server link.
By default, NAT will map all ports according to the
traditional IP NAT protocol. However, the user may opt
to map specific ports or a range of ports to a specified
IP address on the LAN. It is also possible to map all
ports to a specified LAN IP address. You will use this
same window if you are using NAT for a multiple
number of IPs.
To specify NAT mapping, type in the port or range of
ports used for mapping in the Start Port Number and
End Port Number columns and enter the LAN Local
IP Address of the server or system used for the
selected ports. To map a single port, type the port
number in both Start and End port entry fields. Click
the SAVE button to apply the NAT port mapping and
save the settings.
