If it matters the port 445 user is a XP user if that matters.

It's all bad.

I took my Powerbook down there and it was slow also.  I need to test  
it again to be sure but I thought that my OS X system was a tad  
faster.  Still painfully slow but faster.

The native Windows to Windows file sharing is not an issue.  If a  
client on the downtown LAN shares a folder the VPN user can access  
the share with decent, usable speeds.  Also our old Dell fileserver  
running Samba 2.x works well across the VPN also.

This is on the Xserve right?... with <interface> being my LAN  
connection en0 I believe.
