[pptp-server] ipx over pptp

[Mark Lin]

Mr.  Grim:
      Maybe I should make it more clear, what I really want is to have IPX over IP VPN.  I think we have a little miscommunication.  First of all, I don't think all the network interfaces need to have the same network number, at least for my game purpose. They could be any number, but what I really want is to have VPN(virtual private network) server(pptpd) set the incoming connections(IP) to a same network number(IPX) and different node numbers(IPX).  Secondly, does it matter if the network interfaces think it's receiving ipx data from different ipx network?  It doesn't, because it's receiving IP data, not IPX.  
    I know one thing for sure that pptpd of VPN server assigns a different network number for each connections, that is if the range of ipx nets was specified in its configuration file.  I also notice that pppd, which pptpd used as dial-in server, has the options for ipx-network and ipx-node in its option file, but even when I add more node in one network in the option file(/etc/ppp/options), one the first computer can get ipx, and the next client simply wont have IPX networking.  I guess ipx-node option is probably for the computers on the same lan with the connecting computer.  Maybe I mess up somewhere in ppp options, but please tell me where.

    Lastly, i just found out there IS a program doing specifically bridging two ipx networks called IPXTUNNEL. It's available on ftp://sunsite.unc.edu/pub/Linux/system/network/daemons/
made by Andreas Godzina ag at agsc.han.de.
I havn't try the program yet, but if any of you have experienced with it, please reply to me, I would really like to get this IPX over IP thing going for my game! :))


cheers,
Mark

  There is no way as far as I can tell to give all network interfaces the same network number. I'm going to hopefully begin work on a server daemon that'll "trick" all the network interfaces to thinking they are all recieving ipx data from the same network number. It isn't a problem with routing. IPX broadcasts are designed to travel within their network only. If anyone on this list has any info on how to go about coding such a utility please let me know though =). I'm an experienced coder, I'm just not familiar with linux.

  Also, DON'T confuse ipx with tcp/p. The IP address has NOTHING at ALL to do with IPX, the ip address is a tcp/ip issue, not an ipx one. They are too completely different protocols. If you didn't even run tcp/ip and no one even had ip addresses, ipx would still work.

  Hi all:
   I've recently due to gamer's need, set up a VPN server using pptpd in redhat 6.1, kernel 
  2.2.20-12. Everything works, my friends can all login to my vpn server and browse each other's network neighborhood which is all good except that most important part wasn't working. We trying to set up VPN server with IPX encapsulated in IP so that we could play network game, such as half life, inLAN mode. By using VPN, wefigure that sinceeach client is given a temporary MAC address and IP, the game should recognize it as aLAN game. Butso muchfor our anticipation, we couldn't see any thing in LAN which means that our IPX doesn't get routed. Another interesting fact, after my clients log in to VPN server, their ip will change to the ones I assigned to them in PPTP server when you use 'winipcfg' in windows98.But when the game starts up, it still use the orginal IP and MAC address instead of the one that was assigned by VPN server. 
  
  I e-mailed the author of IPX+PPTP HOWTO about my question, he says and I quote "ipx usus different network numbers for each connection i believe, this is siminar to the subnet in tcp. If the game doesnt support specifying the remote ipx network then you wont be able to use ptp :(  Kevin "
  
  I guess now my question is, anyone knows if there is a way to put all the incoming connection from pppd to a same IPX network number?? Or just simply anyone already experimented with VPN for LAN game purpose? (I wont believe no one ever thought of this before me, this probably has been done long time already since the introduction of VPN, but maybe NT's VPN would be easier for this kinda task??)
  
  Cheers,
  Mark
