With a line of
pty "/usr/sbin/pppoe -I eth0 -T 80 -m 1412"
and
mtu 1492
ifconfig ppp0 still shows an MTU of 1492. Though I'm guessing that's
what it should be showing, based on Anoop's reply, below. Eth0 (the
interface that pppoe runs on) of course has an MTU of 1500. If I'm
misunderstanding though, feel free to tell me. :-)
Thanks,
