It's a good thing your ISP knows what they're doing! I have a feeling if 
I were in your situation with Bellsouth, I would have spent weeks 
talking to people telling me to reboot my DSL modem and then given up. 
My previous statement about coding practices still stands, however. :-)

Success! I am online via PPPoE with my m0n0wall :)
I have to give really big props to my ISP. They made an adjustment to my 
account. They said they turned of multilink. Once they made the 
adjustment the m0n0wall was able to connect.
