Problems connectig to a VNC server behind an ISA Server

[James Weatherall]

Jorge,

Please see http://www.realvnc.com/portforward.html, in particular some of
the links contains useful info.

In order to get in to the server, you'll need to forward a TCP port on your
firewall to TCP port 5900 on the server computer, for inbound connections.
How to do this should be described in the ISA Server 2000 documentation.

Cheers,

Wez @ RealVNC Ltd.
