VPN Query

I have successfully setup our windows vpn to allow users to dial into the network to retrieve emails etc.

As mentioned it is a standard windows vpn.

I have noticed that when dialed in via the vpn I am able to ping all our servers except one.

I am unable to ping the server by ip or server name.

I can sucessfully ping this server inside the network but not via vpn. This is cauing problems with our voice over ip system for vpn users as the server in question is our phone server.

Also our subnet mask here is 255.255.255.000 and gateway 192.168.175.1 but whenever I connect via vpn it assigns me a subnet of 255.255.255.255 and gateway of 192.168.175.68

When dialed in via vpn I assumed it should asign the same subnet and gateway as the network.
 
Can you do a traceroute from your workstation that is on the VPN? it will tell you where the packets are being dropped.

What exactly is your message when you ping?

As far as having an IP with a /32 mask, it needs to do that i figure because it needs to set a route saying that to reach your PC, the next hop is the VPN concentrator. I figure it's normal.
 
I am seeing request timed out messages after the first hop once the trace route leaves the client pc.
 
Doublecheck your IP stack on the server in question - ipconfig /all

Now, connect a workstation via vpn and give an IP stack print out of that too...

that would probably give us a place to start helping.

I agree, the /32 is normal and expected with Windows VPN as compared to Cisco or something else. At least that's been my experience too.

ipconfig /all from the server
