Configuring NAT
The P-791R v2 has 7 remote nodes and allows you to configure 8 NAT
Address Mapping Sets, You must specify which NAT Address Mapping Set
to use in the remote node when you select Full Feature NAT.
You can edit 10 rules for each Address Mapping Set. You can edit the rules for
Address Mapping Sets #1 in Web Configurator. The other Address Mapping
Sets #2~8 can only be configured in CLI (Command Line Interface).
The NAT Server Set is a list of LAN side servers mapped to external ports. We
can configure it in Web Configurator, Advanced Setup, Network -> NAT ->
Port Forwarding. To use the NAT server sets you've configured, a Server
rule must be set up inside the NAT Address Mapping set. Please see NAT
Server Sets for further information on how to apply it.
When you select SUA Only, the P-791R v2 will use a default SUA Address
Mapping set for it. It has two rules: Many-to-One and Server. You can see it in
SMT menu 15.
