What comes up are packets from a host in my local network getting sent 
out over ppp!  Every time a packet with the source from my internal 
network gets sent over ppp, the connection reconfigures. You were

Which means that my iptables NAT script isn't doing its job. I've never 
claimed to be an iptables expert which is why I've always used 
MonMotha's iptables firewall.  I guess its time to learn....
