P-791R v2 Support Notes

It is because SUA makes your LAN appear as a single machine to the outside

world. LAN users are invisible to outside users. So, to make an internal server

for outside access, we must specify the service port and the LAN IP of this

server in Web configurator. Thus SUA is able to forward the incoming packets

to the requested service behind SUA and the outside users access the server

using the P-791R v2's WAN IP address. So, we have to configure the internal

IPsec client as a default server (unspecified service port) when it acts a server

gateway.

Note: The NAT type should be SUA only, then you can edit port

forwarding.

22. What is Traffic Redirect?

Traffic Redirect forwards WAN traffic to a backup gateway when the

Prestige cannot connect to the Internet through its normal gateway.

Thus make your backup gateway as an auxiliary backup of your WAN

connection. Once Prestige detects its WAN connectivity is broken,

Prestige will try to forward outgoing traffic to backup gateway that users

specify in traffic redirect configuration menu.

23. What is Dial Backup?

It is Auto Fail-over and Fall-back WAN Backup Solution.

The P-791R v2 features a Fail-over and Fall-back WAN Backup Solution for

complete reliability. When the DSL connection fails, traffic is forwarded to

either a backup ISDN or analog modem to maintain data exchange. When the

DSL connection is re-established, traffic will be fully restored. The WAN

Backup Solution saves device maintenance cost and reduces loss from daily

operation.

In addition, P-791R v2 also performs backup functions by redirecting traffic to

a specific gateway to ensure availability of the Internet connection.
