Linksys BEFW11S4, VPN, and UPnP

Hello folks,

I have the above router wired to a Windows XP SP1 PC acting as a VPN
server for client connections originating from the WAN side. I also require
UPnP functionality because all machines behind the router, including the VPN
server, use Windows Messenger to transfer files, etc. to contacts. I have
noticed that a VPN connection to the server 'breaks' the UPnP capabilities
of this machine as evidenced by an immediately disappearing Internet Gateway
icon. Once the incoming VPN connection settings are deleted, the Internet
Gateway and hence the UPnP capabilities of the machine resume. I then have
to recreate the incoming VPN connection settings. I would like to maintain
the ability to have incoming VPN connections while also maintaining full
UPnP. Is this issue a bug with the OS or the router? I can repeat this
behaviour on any and all PCs behind the router so am inclined to think the
problems resides with the router.

Has anyone got a VPN server set-up using Windows XP SP1 with UPnP enabled
and noticed this apparent bug, no matter what router they are using
(provided of course that it is UPnP-capable)?

Thanks for any advice,

Dave

Almost forgot, the incoming VPN connection settings are configured to
provide an IP to the WAN client in the same range, though unused, as those
machines directly connected to the router. Don't know if this makes any
difference.
