DNS issues with clients connected via AT&T VPN
Posted on 2013-01-23
I hope someone can help. I have an issue whereby, when clients connect to the VPN, I cannot ping them or access them via their computer name. This means that when the helpdesk are trying to troubleshoot issues, they have to get end-users to find out their VPN IP address.
I have just tested it with a new client (XP but most are Windows 7). I joined the client to the domain then disconnected it from the corporate network. I connected it to a broadband connection then connected to the VPN. I then tried to ping it by its name from my machine. When I do this I get:
Reply from 10.132.1.185: Destination host unreachable.
10.132.1.185 is my machine that I'm pinging it from so I'm a bit confused by that. So I then tried pinging from another internal server on our network, and it just times out.
I did an NSLookup on the client and it is using our internal DNS server and resolving names correctly. I also checked the bindings and the VPN adaptor is at the top.
Does anyone have any ideas how to resolve this?
DCDiag /test:DNS checks out fine.
