Port forwarding server

A NAT server set is a list of inside (behind NAT on the LAN) servers, for

example, web or FTP, that you can make visible to the devices using the VPN

branch NAT tunnel (from behind the remote IPSec router) even though NAT

makes your inside network appear as a single machine. The servers must be using

the VPN branch NAT tunnel (from behind the Business Secure Router).

You can enter a single port or a range of ports to be forwarded and then the local

IP address of the desired inside servers.

Configuring a port forwarding server

Select one of the IP Policies in the VPN Branch Office screen and click Edit to

display the Branch Office – IP Policy setup screen. For the Mapping Rule Type,

select Many-to-One, enter the private and virtual IP addresses and click the Port

Forwarding Server button to display the screen shown in Figure 73.

When the Address Type field is configured to Subnet Address,

this is a subnet mask on the LAN behind your Business Secure

Router.

535. Some of the most common IP ports are: 21, FTP; 53, DNS;

23, Telnet; 80, HTTP; 25, SMTP; 110, POP3.
