IS there a way to change the pptp port a windows client VPN connection uses?
I have a network with several XP machines which accept VPN connections. To
have more then the one connection coming in, they need to be routed to
different computers in my network. I can tell my router to send external
port 1723 to 1723 on computer A, 1724 to 1723 on Computer B, 1725 to 1723 on
computer C, so i don't need to change the incoming port of the VPN servers
as the router does the re-routing, but i do need to be able to get the
client machines to connect via a non standard (non-1723) pptp port. Does
anyone know how i might be able to achieve this? Thanks Ben.
 
Why do you need vpn connections to multiple computers on the same subnet?
Once your VPN is up, you can connect to any other computer on the LAN.

To have multiple computers connecting in.

You can have up to 10 computers connecting from a W2K or XP Pro box, and as
many as you have CALs for on a server.

WinXP can only accept one VPN connection. IF you know how to make it accept
more then one, please let me know.
Thanks

According to the Windows help for XP Pro, it will accept 3 incoming
connections. Granted, this is a lot less than 10 - but more than one.

Have you got a link to that information?
I read an article saying that XP can only accept one incoming, and when i
tested it with more it says on all subsequent connections after the first is
made, that there is already a connection and it fails.

Thanks

I went to the start bar, clicked help, and searched for "Incoming
connections" or something close. It's right out of the XP Help.
Unfortunately, my XP Pro boxes are domain members (which removes the ability
to allow incoming connections except for DCs and member servers), so I can't
get to the wizard to try it out. Check out snapgear lite (free Linux PPTP
VPN server and client software). Did I mention it's free? Or for a simpler
setup, look at the CyberGuard SG300. Accepts Windows PPTP and L2TP
connections (Street Price around $250.00).

Thanks Kurt. I've found the information you had found:
"By creating an incoming connection, a computer can act as a remote access
server if it is running Windows 2000 Professional, Windows XP Professional,
or Windows XP Home Edition, or if it is a stand-alone computer running
Windows 2000 Server. You can configure an incoming connection to accept the
following connection types: dial-up (modem, ISDN, X.25), virtual private
network (VPN) (PPTP, L2TP), or direct (serial, infrared). On a computer
running Windows 2000 Professional, Windows XP Home Edition, or Windows XP
Professional, an incoming connection can accept up to three incoming calls,
up to one of each of these types."

So it can take three incoming connections, but only one of each type VPN,
dial up and direct connections.

Thanks for your Unix based suggestions, but i have never used it before and
have nothing set up with it at the moment. However if i want to have
multiple connections i guess i will either have to get a windows server
edition, set up a computer with linux or get a router which can support vpn
connections, as there doesn't appear to be any windows software to do it,
and it appears impossible to have vpn tunnels going to multiple computers
inside the router.

Thanks
Ben
