As far as I know, no, because that would be like a "man in the middle" attack (I think). Like this:
A <--- B ---> C
If A is talking to C via IPSEC, A tells C it's IP (the true IP) and C tells A it's IP (its true IP, behind the masquaraded host), but A sees C as B's IP address. How does it know that C knows that B exists? Maybe there is a way to forward or tunnel certain protocols through the Linux box, but this doesn't sound like a good idea to me. You could always use the old crusty SSH tunneling VPN's.. :)
Eric
P.S. - Don't ask how to do it with SSH. It's been too long.
