Anyone here good with VPN servers?

I need to configure a VPN server so that one machine can connect to it from the same subnet, and from other subnets. The end goal is that the client can appear to have the same IP address (the server's) regardless of what subnet it's on.

I'd rather use pptpd but would consider openvpn, ssh tunnels or other options. The OS of the serve is Ubuntu 10.04 server and the client is Ubuntu 10.04 desktop, both are completely fresh installs, the server only got LAMP and SSHD ticked during install.

So what information do I need to provide, if there's anyone who knows how to do this?

It's been suggested, but the application is actually ssh, while it's really easy to make a tunnel with ssh, it's hard to use one with ssh, hence just routing everything via a VPN.

I'm basically sick of having to re-start all my ssh sessions when I go wireless or dock the laptop.

It's not, it's totally not.

"Put your local address here and remote addresses here" wut? "Set up a bridge" ok? "Use tis to choose between a tap and a tun" you're making this up, surely?

I'm very familiar with networking and TCP/IP (more of a SAN guy though), but OpenVPN is just twaddle.

I got the local address, obviously, but remote address? I tried a range of 10.8.... addesses for the client to be assigned, but the server never started. My level of understating is enough to know what broadcast is, what can and cannot be a block of IP addresses.

A bridge I get the concept of, but can't see how it applies to the application.

tap and tun are alien to me. But all the "easy" guides I can see tell you to choose which you need an put it in the config file. I don't know what I need, if I knew that I probably wouldn't need a guide.
