Frame-relay with private ip

I am consulting with a company that has 15 remote sites connected to the main office. The main office is running frame-relay through one interface that is sub-interfaced into 15 sub-interfaces to serve the 15 offices. All the interfaces are on an internal private network that has one access point to the the internet at the main office. Supposedly, the provider has stated that each office in the internal network needs to have a public IP address which seems unnecessary . Is this their any reason that each site that is within the internal network should have a public IP address? Or, can we use a total private IP addressing scheme in the frame-relay cloud while having one access point with a public IP address on the main office router to get us out to the internet.

Re: Frame-relay with private ip

With NAT you should be able to have only the Main office have a (1 or a pool of) public addresses. Most reasons for public addressing are being reachable from the public address space, which you can also do with NAT static translations into your corporate network. So, to answer your question, Yes you can do this without public address space and still allow all your satellite offices to get to the internet. Don't quite know what your providers reason is unless they charge your more for address space and are just trying to make more money... ??? Just a guess

Hope this is what you were looking for,

Don
