FVS338 ProSafe VPN Firewall 50 Reference Manual
Connecting the FVS338 to the Internet 2-17
v1.0, September 2006
This router firmware includes software that notifies dynamic DNS servers of changes in the WAN
IP address, so that the services running on this network can be accessed by others on the Internet.
After you have configured your account information in the firewall, whenever your ISP-assigned
IP address changes, your firewall will automatically contact your dynamic DNS service provider,
log in to your account, and register your new IP address.
To configure a Dynamic DNS address:
1. Select Network Configuration from the main menu and Dynamic DNS from the submenu.
The Dynamic DNS Configuration screen displays. The WAN Mo de section displays the
currently configured WAN Mode: Single Port or Auto-Rollover.
If you have configured Single Port, choose a DNS service provider, then fill out the DDNS
section for that port. If you have enabled Auto-Rollover, choose a service provider and
complete both sections. (Only those options that match the configured WAN Mode will be
accessible.)
