Hello everyone,

I recently (successfully) configured MPD-netgraph as a pptp server on my
FreeBSD machine.  It works great... for one user.  When I change my
configuration to support multiple PPTP bundles/links I get the following
error when starting mpd:

bsd# mpd
Multi-link PPP for FreeBSD, by Archie L. Cobbs.
Based on iij-ppp, by Toshiharu OHNO.
mpd: pid 518, version 3.7 (root@bsd.imagineering.ca 16:39 28-Feb-2002)
[pptpbundle0] ppp node is "mpd518-pptpbund"
mpd: local IP address for PPTP is 192.168.0.253
[pptpbundle0] using interface ng0
[pptpbundle1] can't name ppp node: Address already in use
[pptpbundle1] netgraph initialization failed

I have varied the IP address assignments in my configuration files, and
examples on the web have duplicated IP addresses between bundles without
causing this problem.

Does this make reference to the ppp node name (mpd518-pptpbund)?  And if
so, how do I change what the ppp node name will be?

Best regards,

Ryan Morris


Here are my configuration files:
