(Copied from http://forum.pfsense.org/index.php/topic,40671.msg209656.html#msg209656)
Attached are four files. Here's how I got them:
1. Boot system fresh. PPPoE connected.
2.clog /var/log/system.log | egrep '(mpd|ppp)' > ppp_working.txt
cp /var/etc/mpd_wan.conf mpd_wan_working.conf.txt
3. Pull plug on WAN NIC. Wait 2 minutes. Re-plug. (WAN not connecting)
4.clog /var/log/system.log | egrep '(mpd|ppp)' > ppp_not_working.txt
cp /var/etc/mpd_wan.conf mpd_wan_not_working.conf.txt
5. Reboot to working WAN.
Null Service Name is checked.
