ZyWALL 10/50 Internet Security Gateway

IP address that changes each time you reconnect. Your friends or relatives will always be able to call you even if they don’t know your IP address.

First of all, you need to have registered a dynamic DNS account with www.dyndns.org. This is for people with a dynamic IP from their ISP or DHCP server that would still like to have a DNS name.

To use this service, you must register with the Dynamic DNS service provider. The Dynamic DNS service provider will give you a password or key. The ZyWALL supports www.dyndns.org. You can apply to this service provider for Dynamic DNS service.

4.2.1 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.
