Yes, you need to setup L2TP on the 3com and then setup a L2TP client on Windows XP, that works when the Windows XP client has a public ip-address, but not when it is behind a NAT router (atleast I couldn't get it to work).
I followed the documentation on the 3com site about setting up the client, see

can also be found in the download section.
See

for info about the 3com Superstack 3 firewall.
