My desktop machine is a Windows 7 PC. I need to access some file shares on the remote Windows server JASON using a set of Windows credentials. However, the server JASON is behind a firewall, so to access it I normally have to connect to a special VPN.

However, I do not want to use the VPN as the VPN messes up my other network access. What I would rather do is connect through a third server BASTION that is behind the same firewall as JASON. I have an account on BASTION that I can use SSH to access.

WINDOWS 7 --> port 22 -.  | BASTION --> JASON |
                       |  |  ^                |
                       '-----'                |
                          |                   |

How can I map the remote share on JASON to my Windows 7 machine using BASTION as a proxy. I am thinking I can use the putty client, but I do not know the next steps.

I do not think this is possible. Why does VPN mess up your network? – MichelZ Jul 24 '12 at 19:59
When the VPN is on it blocks me from other servers that are not behind the firewall and do not allow machines behind the firewall to access them. – user35042 Jul 26 '12 at 15:34

You should rather fix your VPN. If you're using Windows built-in VPN, try:

On the VPN Connection properties:

-> Networking -> Internet Protocol Version 4 -> Advanced... -> Unceck "Use default gateway on remote network"

This ensures that you are NOT using the VPN's default gateway, but your local one. You should retain network access to your local network.

I am using the Cisco VPN Client, not the Microsoft one. – user35042 Jul 24 '12 at 20:05
Can you try their AnyConnect client?… – MichelZ Jul 24 '12 at 20:10
