I updated my gateway using freebsd-update, and rebuilt my kernel after
making sure I had the latest sources. I proceeded to install mpd4 and
try out the configuration Nikos linked to. So far I haven't had any
success. I tried adding 'set bundle enable round-robin' since that's
how this is going to work on the download side of things, still
without success.

mpd.conf:
------------------------------------------------------------
startup:
        set console ip 127.0.0.1
        set console user username password
        set console open

default:
        load PPPoE
        open

PPPoE:
        new -i ng0 sam l0 l1
        set auth authname username at teksavvy.com
        set auth password password
        set bundle enable multilink
        set bundle enable round-robin
        set iface idle 0
        set iface route default
------------------------------------------------------------

mpd.links:
------------------------------------------------------------
l0:
        set link type pppoe
#        set link mtu 1486
#        set link mru 1492
        set pppoe iface xl0
        set pppoe disable incoming
        set pppoe enable originate

l1:
        set link type pppoe
#        set link mtu 1486
#        set link mru 1492
        set pppoe iface xl1
        set pppoe disable incoming
        set pppoe enable originate
------------------------------------------------------------

and finally, the log file:
