Why this value?
Because of this:
-- 1464 seems to be the biggest value I can set for the ping without
getting the "Packet neesd to be defragmented but DF set" message from
ping.
-- how this relates to the MTU I have set in my modem. I don't know.
Currently set to 1492 but changed it to MTU=1500 because it is now
back to using PPPoA
