Automatic Settings
Pressing the "Automatic Settings"
button, or selecting it from the popup menu, sets everything to
"Remove" apart from TTL and,
in Win95, NDICacheSize. It also enables PMTUAutoDiscovery and PMTUBlackHoleDetect.
These settings seem to give reasonable
performance once Winsock2 has been installed on a Win 95 machine.
The Win NT default is PMTUAutoDiscovery enabled and
PMTUBlackHoleDetect disabled.
