server is available, the WRP400 can perform a NAT-type
discovery operation when it powers on. It contacts the
configured STUN server, and the result of the discovery is
reported in a Warning header in all subsequent REGISTER
requests. If the WRP400 detects symmetric NAT or a
symmetric firewall, NAT mapping is disabled.
The default is
no
.

server to contact for NAT mapping discovery.
