[pptp-server] Numerous Questions (IPX and pptpd.conf)

[Andrew Miklas]

Hi all,

I have been thoroughly reading up on the archives for this list; however, I 
may have missed a few posts in which case my questions might be a bit 
redundant.  As well, my first two questions have to do more with routing and 
pppd than PoPToP.

I have successfully got PoPToP to work using TCP, and it correctly attaches 
the single client to the network.

My first question is:
Will PoPToP connect two networks together if the "client" computer is a 
Win98 station.  Will the Win98 station require special routing?

ie.

Win 98 ---------------\                                (ppp link)
Win 98 ----------------> Linux Machine with PopTop <----------- Win 98
Win 98 ---------------/

This is my current configuration.  It seems to work (only TCP though).  
However, will this work?

Win 98 -----\          (ppp)                       /---------Win 98
Win 98 ------> Linux <-------- Win 98 (1)<----------Win 98
Win 98 -----/                                        \---------Win 98

Will the computers at the far right be able to see the computers at the far 
left?  Will the computer marked Win 98 (1) require special routing rules 
before this will go?  If so, how can the Win 98 computer be configured to 
not only route TCP but also IPX data?

Next Question:
I need IPX to work on this entire system.  I have been able to get IPX to 
work (ie. PPPd assigns the client a IPX Net Address and Node Address.  
However, the computers on the far left cannot see the computer marked Win 98 
(1).  I have read that one daemon called ipxd will handle routing between 
all networks on a system, but I have been unable to find this package.  Does 
anyone know where I can find it? Has anyone been able to set up a ipx 
network using PoPToP?  I have been trying to use ipxping to test the setup 
but I can't seem to figure out how to use it.  (Pretty pathetic, huh :)

Next Question:
What "device" does PoPToP use to connect with.  When configuring PPPd (with 
a pool of modems), you use files such as "options.ttyS1" to assign IPX 
addresses to incoming calls.  However, with PoPToP, I can't figure out what 
I should name the files.  Currently, I put my IPX configuration info in the 
"options" file, but this won't allow more than one client to connect.  How 
do I specify a pool of IPX node and IPX addresses to give out to connecting 
clients?

Next Question:
What does the speed parameter do?  The tunnel (which goes over the INET) 
uses a high speed connection between the two sites.  The Win 98 client 
reports that it connects at 10 000 000 000 bps (which is correct, as that is 
supposed to be the through-put of the connection).  However, the PoPToP logs 
indicate that I am only connecting at 115200 bps.  Which is the connect 
speed?  If it is only 115200, is it possible to get it to work faster?  When 
I set the speed parameter in the pptpd.conf file to 10000000000, the PoPToP 
logs tell me it is an invalid parameter.

I realize that my IPX question is really vague.  Right now, my only way of 
checking the IPX configuration is to boot up a game of MS Age of Empires on 
one of the computers on the far left with the machine Win 98 (1).  (pretty 
professional huh :)
