Sorted now (kind of) & it is the router. If I configure the incoming VPN to
use DHCP to assign ip addresses it fails. If I assign addresses from the XP
box it works.

No name resolution though. I can ping via ip addresses, but not via names.
Any idea on how I can get that to work without installing a DNS server at
the remote location?
