Dynamic DNS
A dynamic DNS service is useful when you don’t have a static Internet IP address, but
need to remain contactable by hosts on the Internet. Dynamic DNS service providers
such as TZO.com and dyndns.org can register an Internet domain name that will point to
your Internet IP address no matter how often it changes.
Whenever its Internet IP address changes, the SnapGear appliance will alert the dynamic
DNS service provider so the domain name records can be updated appropriately.
First, create an account with the dynamic DNS service provider of your choice. Click the
red TZO logo if you wish to take advantage of the 30 day free trial with TZO.
Next, select your chosen Dynamic DNS service and click Continue . Select which
interface/connection’s IP address you want associated with your newly created DNS
name from
Internet Connection . Enter the details provided by your dynamic DNS
service provider and click Apply to enable.
