I've just recently configured the PPTP VPN option in m0n0wall without a
problem. When I use the static username and password assignments the
tunnel comes up without a problem, however I have a requirement to use
RADIUS authentication. I enable RADIUS and enter the parameters, yet
authentication consistently fails. The connection hangs for a bit on
verifying username and password, and windows users get the error
"Disconnected: error 619". Naturally, I check to see if RADIUS packets
are passed from the m0n0wall firewall to the RADIUS server; they are not
I setup a dummy box to dump all ports for any host that attempted to
connect to it and configured m0n0wall to use this device as it's RADIUS
server; no ports were connected too.
My first thought would be that it's a firewall related issue, where I
have to allow m0n0wall to connect to the RADIUS server, but I checked
the firewall logs and there were no related events to the m0n0 box
attempting to connect to the RADIUS server.
Any ideas as to what the problem is? I didnt see any documentation on
the website relating to RADIUS configuration short of "just enter it,
it's not in the scope of this document".
