DNS:
The Digi Wi-Point 3G supports dynamic DNS (DDNS). The default status for DDNS is
disabled. The Digi Wi-Point 3G only supports DNS provided by www.dyndns.org. To use
this feature, obtain a domain name from the provider. The router will register the new
public IP address every time the wireless WAN IP changes.

Virtual Private Networks (VPNs) are used to securely connect two private networks from
one to the other using secure channels. VPN uses IP Security (IPSec) technology to

For more information on setting up VPN, please refer to Digi Application notes.
