Gleb,

	My ppp.conf haven't been changed from the time this machine have 
FreeBSD installed. Password configured is the same that I'm successfuly 
using now with rp-pppoe.
	Please look at this successful rp-pppoe session log. I see MRU is 
really changed to 1500. Why ng_pppoe can't do this anymore?
	OS/hardware on the remote side is beyond my knowledge. I could try to 
find it out, but it may take some time.
