[pptp-server] How can I manage my win98 box to handle two ppp connections at the same time?

[Risko Peter]

Hi All!

  First, I must beg your pardon for the long letter, and the terrible English
I use in it...

  I am trying to establish a pptp link between a Linux box, and a win98
machine. On my local ethernet network it works well: the server has IP num.
192.168.2.1, the win98 is 192.168.2.2, and I can 'dial' the server from the win
machine. After dial, I can check the connection on the Linux box: in the syslog
I see this (both ppp and pptp is in verbose mode):

  But if I start a dial-up connection from the win machine, and then 'dial' the
pptp server on the local lan, they can't establish the connection. I see
this in the syslog (both ppp and pptp is in verbose mode):

  So, it seems for me that my win98 machine can't handle two ppp connection at
the same time.
  Finally I would like create a pptp tunnel over the Net from the win machine
to a Linux box on the Net. For this, I will have to establish two ppp conns, 
a dial-up connection to an ISP, and then a 'dial' to the pptp server.

  Have you any idea?
