Hi Stuart,
As some have replied offlist, I tried to change the MTU and change
authentication to pap but to no avail.
You can try these to see if they give any clues:
- 'ifconfig pppoe0 debug' and watch dmesg
- 'tcpdump -nvvs1500 -iem0' (where 'em0' is the parent device of pppoe)
Here are some logs :
