Chapter 20 DNS 347
20.10.1 DYNDNS Wildcard
Enabling the wildcard feature for your host causes *.yourhost.dyndns.org to be aliased to the
same IP address as yourhost.dyndns.org. This feature is useful if you want to be able to use,
for example, www.yourhost.dyndns.org and still reach your hostname.
20.10.2 High Availability
A DNS server maps a domain name to a port's IP address. If that WAN port loses its
connection, high availability allows the router to substitute another port's IP address for the
domain name mapping.
20.11 Configuring Dynamic DNS
To change your ZyWALL’s DDNS, click DNS, then the DDNS tab. The screen appears as
shown.
Figure 173 DDNS
Note: If you have a private WAN IP address, then you cannot
use Dynamic DNS.
