Dynamic DNS
A dynamic DNS service is useful when you don't have a static 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 points to your IP
address no matter how often it changes.
Whenever its Internet IP address changes, the SnapGear unit alerts the dynamic DNS
service provider and the domain name records are updated appropriately.
First, create an account with the dynamic DNS service provider of your choice, then
select this service provider from the Service pull-down menu and click New.
Select the Port that you want associated with your newly created DNS name. You may
select Default Gateway Interface to have the SnapGear unit use the external port of
your Internet connection.
Enter the details provided by your dynamic DNS service provider and click Apply to
enable.
Static hosts
Available static hostnames display here. These hostnames can be resolved to IP
addresses on this device even when DNS is not available. These static hostnames are
stored in the /etc/config/hosts file. The DHCP server reserved hosts list is also stored
here, but do not display in the Static Hosts list.
Static hostnames can be created, modified, or deleted from this page.
