I've got an issue with a VPN I need a bit of help with. Senario is:

Site A. has a XP Pro box configured for Incoming connections, with ADSL
connection.
Site B. has 2x XP Pro laptops, with ADSL connection.
At both sites the wireless ADSL router is a Linksys WAG54G.

I'm aware of the limitation of XP Pro only accepting 1 concurrent incoming
connection.

This setup is required so that the 2 users at Site B, can come in to the
office (they're out with clients most days), connect to the network, connect
to the VPN & syncronize the companies main file share (at Site A), then
disconnect.

The problem is:
If laptop A connects to the VPN, syncronizes (or not), then logs off the
VPN, laptop B can't get a connection to the VPN at Site A (I've checked that
the connection has been dropped at site A). laptop A can connect,
disconnect, connect, disconnect (and on and on). But laptop B can't connect
to the VPN at site A, until both laptops have been rebooted. laptop be is
getting a 721: no response from server.

What do you guys think? I'm thinking it may be the WAG54G, but I'm not
sure... I haven't called linksys, and I'm sure level 1 support doesn't have
this on there standard list of answers ;) and the linksys website hasn't
been very helpful.

(ps. the company will be getting a 2003 server early next year, but they are
a non-for-profit, so it's not an option right now).

Thanks

It might help to look in the logs of the XP Pro computer that is acting as a
VPN server to see if any error/warning messages are being recorded that may
be of help. Another thing you might try is to configure the client VPN
connectoid properties on the laptops to disconnect after one or five minutes
of idle time as by default I believe there is no time limit. There may be a
corresponding "server" setting for idle time in the properties of the XP Pro
box that is acting as a VPN server. --- Steve
