[pptp-server] Emulating a LAN over Internet

[Alberto García]

	Hi, I'd like to know the problems of this setup:


     ,---------.  Priv  ,--------.                       ,--------.
     | Windows |  LAN   | NAT    |     (Internet)        | PoPToP |
     | Client  |--------| Router |- - - - - - - - - - - -| Server |
     `---------'        `--------'                       `--------'
                                                              |
                                                              |Private
                                                              |LAN
                                                              |
                                                         ,---------.
                                                         | Windows |
                                                         | Client  |
                                                         `---------'

	I tested this and it works: both Windows client establish a PPP
connection with the PoPToP server, and both can see each other using the
virtual IP addresses. Now I have some questions:

	- Broadcast traffic from one Windows host doesn't reach the
other, but it does reach the PPTP server (tested with tcpdump). Is there
any generic way for achieving this? Could it be possible to do some kind
of PPP bridge so that both clients behave as if they were in the same LAN?

	- At this moment, when a client connects to the PoPToP server, the
server chooses a free IP from the range specified in the configuration. 
I'd like to know if this could be more configurable: the server chooses an
address depending on which client establishes the connection. Could it be
possible?

	- Is there any problem if two or more NAT'd clients on the same
subnet connect to the PoPToP server using the same public IP? 

	Well, I think that's all :-) Thanks in advance.
