How do I setup my Prestige for routing IPsec packets over SUA?
For outgoing IPsec tunnels, no extra setting is required. For forwarding the inbound IPsec ESP tunnel, A
'Default' server set in menu 15 is required. 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 Menu 15. Thus SUA is able to forward the
incoming packets to the requested service behind SUA and the outside users access the server using the
Prestige's WAN IP address. So, we have to configure the internal IPsec as a default server (unspecified service
port) in menu 15 when it acts a server gateway.
