Configuring DDNS
The public IP addresses assigned to your Telephony Modem can change from time
to time. If you are providing services from your private network (using the Virtual
Servers feature), you should use Dynamic DNS (DDNS) to associate your current
IP address with a domain name. The Telephony Modem directly supports several
major DDNS providers.
After setting up a DDNS account, follow these steps to configure the Telephony Mo-
dem to contact the DDNS provider.
1 Click the Firewall link in the navigation menu, then click DDNS.
The DDNS window appears.
2 Choose your DDNS provider from the DDNS Service drop-down menu.
3 Enter your DDNS account name, password, and DDNS domain name in the
appropriate fields.
4 Click the Update DDNS button.
Note: Your domain name may not be immediately associated with your cur-
rent IP address. Updated DNS information takes some time to propagate
across the Internet.
