VPN is a general term that includes a variety of different ways of encapsulating data. Standard IPSec tunnels require using the AH and/or ESP protocols, which are NOT IP protocols. Some of the common alternatives to IPSec, such as PPTP, use GRE, which again is not an IP protocol. Not all VPN devices are able to encapsulate non-IP protocols to send them over the VPN -- so you might not be able to send the AH, ESP, or GRE packets through the VPN tunnel in order to have them decapsulated by your server at work in order to have them passed on to the remote system. On the other hand, some VPN devices should handle this with no problem: you did not indicate what you are using. There -are- some officially supported ways to do what you want, if you have the right software/hardware at both sides. I am a bit uncertain about the details, though, so I will not say exactly what has to be done.
