[pptp-server] Lost with pppoe and pptpd

[Georg Altmann]

Hi everybody,

It took me some time to find out that pptpd is conflicting with pppoe.

Here is what I did so far:
Recompile+install Kernel 2.4.7 with IP GRE and PPP support with linux-2.4.4-openssl-0.9.6a-mppe.patch.gz,
compile+install ppp-2.4.1 with ppp-2.4.1-MSCHAPv2-fix.patch.gz and ppp-2.4.1-openssl-0.9.6-mppe-patch.gz,
compile+install pptpd-1.0.1
modify syslog.conf

I'm trying to connect a W2k roadwarrior (myself ;) to my linux box which is also the router with pppoe running.
When I shut down pppoe and then fire up pptpd everything works fine.

With pppoe running the log looks like this:

Is there anybody who got pppd running with pppoe?
Could someone explain where the conflict between pppoe and pptpd is located?
Is it that there may only be one instance of pppd running?

The problem for me is, that I need this fixed until friday because I will travel to USA, and that's actually why I'm trying setting this up... ;)
Thanks for any hint!

Regards,
Georg
