[pptp-server] PPP dial outs to ISP fail

[Gord Belsey]

RE: [pptp-server] PPP dial outs to ISP failIt sounds like you may need to set up separate options files for ppp and pptpd.  Their is a flag for pptpd that lets you specify an option file, rather than use the default "options" file.

I came accross this when implementin PPP over Ethernet (PPPoE) for a DSL connection on the PPTP box.  In that case, I had to use an empty "options" file, and set up unique options files for each of PPPoE and PPTPD.  I'm guessing in your case you could use options for ppp and, say options.pptp for the pptpd.  PPTPD will pass the desired options to ppp for the pptp/ppp session.

Hope this helps

  The system doesn't even dial any more..... 

  I would expect the "auth" would be attempted after the modems had connected,  but I could be wrong. 

  How can I ask the PPTP to "auth" and the ISP's ppp not to "auth"?

  Looks like you're demanding that your ISP authenticate themselves to you 
  (they probably won't do that ;-). 

  Check that the options you are passing to pppd for calling your ISP 
  includes "noauth". 

  Perhaps somebody else can suggest why installation of pptpd should provoke 
  this behaviour (one could speculate that it's changing the default ppp 
  options from noauth to auth).
