Purely theoretical unless someone has encountered this...
Is it likely that a companies IT policies would prevent or at least not be too forthcoming with having their SMS internet facing?
I know a lot of companies that would have a management subnet that is not internet facing therefore would not be able to manage remote gateways using the same management server.
Is this something anyone has faced and if so what is the workaround?
My guess is a site to site VPN with a SMS on all sites for local management...
