I'm supporting a small office with a few road warriors who VPN back to the home office file storage computer.
This has all been working fine for months on end with both Windows 7 and Windows 8/8.1 clients.
We are using the Windows firewall throughout the clients.
We are using the Netgear Prosafe VPN Client Professional (which appears to be GreenBow based).
The clients are all terminated on a Netgear FVS336GV2 Router.
Suddenly there are problems.
A remote client can connect the tunnel but can't see the files in the office.
No pings work between the clients and the (whether they did before or not?).
Unfortunately, I don't recall all of the settings that were used but I'm fairly confident that nothing has changed.
So, some of the below is for information and *not* the most likely cause:
The office local LAN subnet is 192.168.234.0/24
The apparent VPN subnet (at least by convention in the clients) appears to be 192.168.2.0/24
(I wonder why it's not 192.168.234.0/24 to match the LAN - but the client software warns if it's set this way).
So, I rather suspect that this is OK and that I just didn't remember this detail and the router
The VPN network connection on the client is showing as a Public Network.
This doesn't seem right to me.
I don't know how to change it to Private... even though I've gone through the typical "howto" steps. I don't know how the VPN client interacts
The original setup has the Private File and Printer sharing items on the clients set to include the LAN subnet in their scopes.
We suspect that there's something about Windows 8.1, perhaps an update, that's changed the good performance. But, we don't know what that might be.
Some users report that rebooting their client computer fixes it for a time. But, I've not been able to confirm this hands-on.
