I have an unusual problem with traffic shaping and PPPoE. I have a 
330kbps upload I (tried) limited to 300kbps for ACK packet 
prioritization. I've nothiced, though, that any web and AIM direct 
connect traffic I have going through my "shaped" WAN interface, it is 
limited down to 250-260kbps. I've tried removing everything and starting 
clean, only using one pipe and forcing all traffic through it, and 
updating to the latest beta (1.1b16) but nothing has changed.

Running java-based speed tests always show the properly limited speed. 
Serving files (web/FTP/Shoutcast Streaming) and directly conneted AIM 
transfers never do. This can be seen no matter if I have the rule set on 
the WAN interface or LAN interface. Doing LAN based file transfers 
between my optional interface and LAN interface shows correctly.

I've lowered my LAN machine's MTU to 1492 and 1456 with the same 
results. I'm only left to think that there is an issue with PPPoE and 
the shaping rules. Could anyone please offer any further suggestions?
