will it allow me to do the following below? Do you know where I can buy a nat traversal lic?
The best way theses days is to upgrade your BCM to release 6.0 and use the Remote Teleworker feature. There are no VPN routers required and you can get a phone set up in about 60 seconds. You will need to get the remote teleworker license, enough licenses for the number of sets you want to register and the associated programming. The biggest thing you need to do is get the right ports forwarded in your internet router. You need to forward UDP ports 7000-7002 and 30000-30099 (BCM50) or 60000-60099 (BCM450) to the BCM's local ip address. Once you have that done, set your S1 address in the phone to the public ip address of your router. Plug the set into any internet connection and voila!
I've done this on a few systems now and it works fantastic! It is by far the easiest system out there as far as remote ip sets are concerned. A real feat on Nortel's part considering their sets were the worst nightmare out there to get working remotely
