The first thing that comes to mind is that you may be dealing with an 
MTU / MSS issue.  Some of your connections work and some never seem to 
start, which is a classic symptom of an MTU / MSS mis-match with the 
ICMP error being filtered out along the way.

Try playing with the TCPMSS match extension and target to clamp the MSS 
to some lower values.  Try something extremely low and then start 
raising it until you start to have failures again and then back it down 
a bit.

PPPoE, despite being nice for providers, has many different problems 
that simple static IPs or even DHCP does not have.
