Dynamic DNS update
Usually, static DNS servers are used to associate a domain or host name with an IP address. If the firewall gets its public IP address via DHCP or PPPoE, the static DNS servers will not work, as they do not automatically change bindings when the firewall get a new IP address.
Ingate Firewall supports dynamic DNS update at DynDNS.org. You must purchase the update service at DynDNS.org before you can use it.
DynDNS.org Configuration
Here, make settings which the firewall will use when updating IP addresses at DynDNS.org. In the descriptions below, the example domain example.com is used.
DynDNS.org status
Select if the firewall should use DynDNS.org services to update IP addresses.
DynDNS.org service
Select which service you use at DynDNS.org.
Username
Enter your DynDNS.org username. This is needed when the firewall updates its IP address.
Password
Press the button to enter your DynDNS.org password. This is needed when the firewall updates its IP address.
IP address for updates
Select the IP address which the firewall should send to DynDNS.org. If a dynamic IP address is selected, the firewall will update the DynDNS.org service every time the address changes.
Wildcard hostnames
If you select to turn this feature On, all DNS queries for any hostname.example.com will return your IP address. If this feature is Off, only queries for example.com will return your IP address.
Offline mode
If Offline mode is on, queries for your domain will be redirected to another URL if your server is down. The URL is entered on the DynDNS.org web site. If no URL is set, queries will be redirected to a general web page at DynDNS.org.
This is an add-on service at DynDNS.org.
Email server
Enter the host name of your email server. This is the name that email DNS queries for example.com should return.
You can't enter an IP address here; neither can you enter a host name that is a CNAME (a kind of DNS alias), but must enter the server's primary name.
Email server is backup
If you selected Off here, the DynDNS.org server will assume that the email server entered above is the primary email server for example.com.
If you selected On, the DynDNS.org server will assume that your primary email server is the one associated with the DNS name example.com, and that the email server entered above is a backup server to take over when the primary server is unreachable.
DNS names to update at DynDNS.org
Enumerate the domain and host names that should be connected to the IP address selected above. If Wildcard hostnames was selected as On, you only need to enter domain names; the DynDNS.org server will return the same IP address for every hostname under the domain. If it is Off, you need to enter every hostname separately.
DNS name
Enter the DNS name to be associated to the firewall IP address.
Delete row
If you select this box, the row is deleted when you click on Add new rows or Save.
Add new rows
Enter the number of new rows you want to add to the table, and then click on Add new rows.
Save
Saves the Dynamic DNS update configuration to the preliminary configuration.
Undo
Reverts all of the above fields to their previous configuration.
