Attention:
Dynamic DNS is not yet supported.
The dynamic DNS service allows a remote host on the Internet to stay
connected to the BSGX4e when it is configured with DHCP or PPP on the
WAN interface. When the BSGX4e is configured with a dynamic IP address
on its WAN port, remote hosts can not stay connected as the BSGX4e’s
address changes. Dynamic DNS allows the domain name data held in a
name server to be updated in real time. This allows the BSGX4e, servers,
and other network devices to use a dynamic IP address but still have a
permanent domain name.
To use this feature, open an account with a dynamic DNS service and
register a host name alias for the BSGX4e with the service provider. Two
dynamic DNS services have been qualified for use with the BSGX4e:
dyndns.org and no-ip.com. Dynamic DNS is disabled by default.
