unable to access a windows 2008 server from windows 7 client through VPN
Posted on 2013-11-08
We've recently installed a vpn server through Routing and remote access on a Windows 2008 R2 server.
We're able to establish VPN connections just fine and most network access works fine as well. There is one problem though.
If we try to connect to a Windows 2008 server on the network, it doesn't work, but only from a Windows 7 client (windows XP works just fine).
It applies to RDP, ICMP, HTTP, HTTPS, ...
I've ran Wireshark on the server which I want to access and when I ping the machine from the client, I can see incoming AND outgoing ICMP messages.
But somehow they're not coming back to the client.
From the same client (ie Windows 7) I can however succesfully access a Windows 2003 server that is in the same subnet as the Windows 2008 server.
My VPN connection has IP address 172.21.250.39
Windows 2008 is 172.21.255.95
Windows 2008 is 172.21.255.90
We've disabled ipv6 on the client to see if that makes a difference, but it doesn't.
We're kind of lost right now, so any ideas would be appreciated.
