Check Enable DNS proxy to enable this feature. If you are using the CyberGuard SG
appliance’s DHCP server, you may also check Update DNS with local DHCP leases.
This allows the CyberGuard SG appliance’s DNS proxy to look up the names of devices
that have requested IP address addresses.
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 points to
your Internet IP address no matter how often it changes.
Whenever its Internet IP address changes, the CyberGuard SG appliance 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 CyberGuard SG appliance use the
external port of your Internet connection.
Enter the details provided by your dynamic DNS service provider and click Apply to
enable.
