I really think it depends on how you are using the ATA. Are you using it as h.323, skinny, MGCP, or SIP gateway. You will need to make sure your NAT device supports what ever signally protocol that you are using.

Thank you,

You have to define several things:

1. The NATIP should be you public IP Address of your NAT server. That’s the IP address that the world sees you.

2. The NAT port number.

Once you done that, you will have to define port forwarding on your NAT router. Basically every time that you receive sessions heading for that port you will forward that to your internal NAT base ATA IP address.
