I am currently running an experimental Cornell reflector at IP 199.72.46.57
on a Linux operating system. People can connect to it with Cornells version
of Cu-Seeme, but nobody can seem to connect to it with WhitePines version of
Cu-Seeme ver 2.1 or 2.1.1 (WFW3.11 or Win95).

UDP port 7648 is set up ( I read somewhere about ports 7648 -7652 ??)
TCP port 7649 is set up
TCP port 7640 is set up

If a friend is connected to the reflector with the Cornell cu-seeme program
and I try to connect to the reflector with WhitePines version, I show up on
the "participants list" of the reflector, I show up as a client with the
"refmon" program, and I show up in the "reflect.log" file, although the
WhitePine version shows "connecting" but never actually shows "connected".
I called WhitePine about this, but they have no idea why this is happening.
Any Ideas ???
