It allows you to tinker with the Windows settings of TCP. I adjusted MTU to 1400, wham-o, all the sites I listed started working; including, what I didn't list before, the downloading of transactions via Quicken. Seems to be a fixall.
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.
