I prefer to have control over (and visibility into) the PPP connection and NAT, to this end I'm seriously considering getting rid of the external ADSL modem entirely, migrating to a Sangoma S518 ADSL PCI card.

It'd help if the OP can provide the output of 'netstat -in' after the PPPoE has been up for a while. > Full-duplex does not detect transmission errors, so you would > not see them on netstat -i output.

Seconded on both points. One thing I've found very helpful in debugging PPPoE has been to use either the "-tttt" (time between packets) or "-tt" (absolute epoch time) options on tpcdump, watching the packets on both the real Ethernet interface and the tunnel (pppoe0) interface, in two side-by-side windows.
