Re: VNC behind ISA Server

Thanks - our situation is that we click the VNC connector & the external
programmers pc is "listening in on port 5500" from what I can gather from
them! - so am I right in understanding that my pc (behind ISA 2004) is
making the call & theirs is listening? - if so I should allow an Outbound
connection from Internal network to Internet for TCP 5500 (but no need to
allow Inbound filter?)
Thanks

You should check if you are using VNC server - this one listens on port
5900 or you "call" their VNC Viewer in listening mode that listens on port
5500...

So this ports are the one to check. For example:

Your machine inside network | ISA | External programmers
VNC server (listens on 5900)

If you want this setup you need to pass port 5900 from internet to
specific IP in your lan.

2 example:
External programmers | ISA | Your machine inside network - you initiate by
left clicking on vnc server and add new client
VNC viewer listening (5500) | | VNC server (listens on port 5900 but it
does not matter)

In this setup you need to allow "calls" from your internal PCs to internet
on port 5500.

Hope it helps,
Luka

Anyone able to help with how to configure permissions for VNC? We have a
site with an application which uses VNC to enable users to call up
support
from the application programmers - however while this works fine for a pc
directly connected to the router, it does not work for those who are
linked
to the SBS 2003 R2 network via ISA 2004. Any ideas? - I suspect that a
new
access rule has to be added to ISA but not sure exactly what or how!.
Thanks
