I'm having a slight issue and needing some advise on VPN's in Windows 8.1. I've setup a VPN using the built in wizard called Incoming Connections however, when I connect to the VPN from another location I can't seen to resolve the Host computer or IP address. I can only resolve IP addresses of things like my NAS box but can't resolve the Host Name of that either or anything else.

I'm not sure what the problem seems to be ?
