MAC Address Clone
A MAC address is a 12-digit code assigned to a unique piece of hardware for identification purposes. Some
ISPs require that you register a MAC address in order to access the Internet. If you previously registered your
account with another MAC address, it may be convenient to assign that MAC address to your ATA. You can
use the Network Setup > Advanced Settings > MAC Address Clone page to assign a MAC address that
you previously registered with your Service Provider.
After making changes, click Submit to save your settings, or click Cancel to redisplay the page with the saved
settings.

VPN Passthrough (ATA 192 Only)
Use the Network Setup > Advanced Settings > VPN Passthrough page to configure VPN passthrough for
IPsec, PPTP, and L2TP protocols. Use this feature if there are devices behind the ATA that require an
independent IPsec tunnel. For example, a device may need to use a VPN tunnel to connect to another router
on the WAN.
