VPN From behind fw/nat to an external ip?

[AHinMaine]

Machine A is nat'ed with a private address, behind a firewall (the config of which I can't change). Machine B has a public ip. I can access Machine B from Machine A no problem. In order to access Machine A from Machine B, I have to jump through Machine C (where I have an acct, but not root).

So, given this, is it possible to set up a vpn so that machines A & B can talk?

My actual goal is to be able to get x11 traffic from Machine A to Machine B, but since I have to go through Machine C, it doesn't cut it. Machine C is not configured to forward X traffic anyway, so a tunnel from B to C to A isn't an option.

I have several customers who have the an issue with SecureID & VPN, when customer dial in via an ISP and then successfully authenticated with secureID, but are unable to ( for example ) replicate within Lotus Notes, however we know TCP/IP is working as I can ping the Company's firewall, I also added the IP address the Host file, unfortunately this has not worked, do you have any suggestions?

Sorry, not that familiar with vpn's in general, let alone on a windows box. --
