I can tell it's getting late, when I reply to myself.
In the scenerio where you have a router be the PPPOE client (in my test
case, it's a Cisco 827 running 12.1(3)XG4), things are still somewhat
broken. The 827 is routing between an ethernet and a PPPOE session, and
even with the 827 having the MTUs at 1492 or 1400, windoze boxen are still
stuck up there at 1500 and those sites don't work. I then use Mr. TCP and
set the ethernet card of the windows box to a MTU of 1400, and voila, it
works.
This really sucks for those folks who will have many machines bechind said
router; it will require a Mr. TCP on each and every one of them.
Sheesh.
