next in thread | raw e-mail | index | archive | help
I use mpd to build VPN connections to one Unix machine and a number of
Windows machines. The Unix VPN is LAN-to-LAN and works fine
regardless of whatever else is going on (though I'm not sure I've ever
had a Windows machine try to get a VPN first). My problem is figuring
out how to allow more than one Windows machine to connect at once.
The Windows machines want to be nodes on the LAN (ptp). There is a
small set of valid login ids for the Windows VPN connections, listed
in mpd.secret. I even gave each one its own ip range, though this is
not necessary and neither fixed nor worsened the problem. The first
Windows machine can authenticate using any valid login and does (I
think) get its correct ip assignment; but then the other Windows
machines can't connect. ("Valid login" here means a key/password pair
from mpd.secret.)
I will include mpd.conf and mpd.links here. 192.168.14 is the local
net for this machine, and 192.168.2 is the remote LAN for the Unix
VPN. I use "new -i ng9" for the vpnwin link because I figured that
would create enough ng* interfaces to support the connections we need.
I'm sure I'm missing something here though...
Please CC any responses directly to me. Thanks much.
