opening sockets behind a firewall
Posted on 1997-11-12
Is there any way (other than using the usual http socket,
I think it is port 80 or 8080) to communicate across a firewall which exist on client's side? If I'm using a socket
for a port # like 1833 ? And if it's absolutelly impossible,
how can the server (or the applet) determine if the client
is running behind a firewall?
