if you move to the current 152 MB/s business service you will get a service that is technically the same as residential, but with a different (better!) repair service.

Modem mode works on that, and in fact will work on the 50 Mb/s service if you do not have a static IP.

Then you can put the SH in modem mode and have the public (dynamic) IP address on the router behind it.

The alternative is to have a routed subnet option and then you can easily assign a publicly routable IP address to the router. This is what I do.

VM Business are due to launch new services in the first quarter of next year (they have said Feb) that will offer fixed IP services on 100, 200 and 300 Mb/s options
