P-791R v2 Support Notes

The P-791R v2 supports NAT sets on a remote node basis. They are reusable,

but only one set is allowed for each remote node. The P-791R v2 supports 8

sets since there are 8 remote nodes.

By fatory default, the NAT is select as SUA in Web Configurator, Advanced

Setup, Network -> NAT -> General -> NAT Setup.

11. Is it possible to access a server running behind SUA from the outside

Internet? If possible, how?

Yes, it is possible because P-791R v2 delivers the packet to the local server by

looking up to a SUA server table. Therefore, to make a local server accessible

to the outside users, the port number and the inside IP address of the server

must be configured. (You can configure it in Web Configurator, Advanced

Setup, Network -> NAT -> Port Forwarding.

12. When do I need to select Full Feature NAT?

• Make multiple local servers on the LAN accessible from outside with

multiple global IP addresses

With SUA, 'visible' servers had to be mapped to different ports, since the

servers share only one global IP. But when you select Full Feature, you can

make multiple local servers (mapping the same port or not) on the LAN

accessible from outside with multiple global IP addresses.

• Support Non-NAT Friendly Applications

Some servers providing Internet applications such as some MIRC servers do

not allow users to login using the same IP address. Thus, users on the same

network can not login to the same server simultaneously. In this case it is

better to use Many-to-Many No Overload or One-to-One NAT mapping types,

thus each user login to the server using a unique global IP address.
