[pptp-server] GRE

[hellhound at linugen.com]

Hi all,

  got some problems with pptpd 1.0.1 (and same with 1.1.2) and Win2k:
  using Virtual Private Connection under win2k, I get:
  Error 619: The specified port is not connected

  on the server side, from messages logfile:
Oct  3 12:25:48 blabla pptpd[8561]: CTRL: Starting call (launching pppd, opening GRE)
Oct  3 12:25:48 blabla pppd[8562]: pppd 2.4.1 started by root, uid 0

Oct  3 12:25:48 blabla pppd[8562]: Connection terminated.
Oct  3 12:25:48 blabla pppd[8562]: Exit.

  I compiled 
    IP: tunneling
    IP: GRE tunnels over IP 
  as modules for my kernel 2.4.9, and loaded the module
  What else do i need to get it working ?

thanks in advance
