[pptp-server] FreeBSD, Samba, PoPToP Connection Problems (internally and externally)

[Charles Peters - Tech Support]

Greetings:

I have a FreeBSD 4.0 server running Samba 2.0.7, and PoPToP-
1.0.0.  I have 2 network interface cards in this machine, one with 
an internal ip address (192.168.0.4) and the other with an external 
ip address (24.4.xxx.xxx).  This machine is connected to the 
internet via a cable modem, and is also connected to a lan on 
192.168.0.

My Windows 98 computer is also connected to the lan, with an ip 
address of 192.168.0.7.  When this machine attempts to establish 
a vpn connection to the internal interface (192.168.0.4), the 
connection is allowed, but when I try and connect to the external 
network card from the win 98 box, I get the following error:

	Error 629:  You have been disconnected from the computer
	that you dialed. Double click the connection to try again.

I also get the same error from computers accross the internet 
attempting to connect to the external adapter.  These other 
computers are also on lans, but have internet access via a cable 
modem and a freebsd gateway running nat and ipfw.  Computers 
connected to the internet via real connections (no nat) also get the 
same error message.

My first concern is where these connection rejection messages 
appear, they don't show up in /var/log/messages or 
/var/log/ppp.conf.

Secondly, how do I fix the problem. As far as I can tell, the vpn is 
working properly inside the lan, the problem is in connecting from 
outside the lan.

It should be noted that I have samba running, and the network 
shares may be being assigned by samba through the lan, and not 
the vpn, but I'll continue to work on that myself.

Any help would be appreciated!

Thanks in Advance!!!
