Renaud,
I have run into the same problem.
I created the following, but mpd does not like it:
pptp:
new -i ng0 pptp pptp
pptp1:
new -i ng1 pptp1 pptp1
I tried starting mpd with:
mpd pptp
then
mpd pptp1
I get the first one started but the second one throws the following error:
Multi-link PPP for FreeBSD, by Archie L. Cobbs.
Based on iij-ppp, by Toshiharu OHNO.
mpd: pid 55054, version 3.0 (root@excalibur 16:48 7-Sep-2000)
mpd: already running as process 55048
I would eventually like to run this software with -b to put it in the
background.
Any help would be great.
Thanks
Chris
