Hi,
 
I had a question from the guys who develop the software, to allow VNC on the server. They use VNC to remotely update their software. As they say it is always the "client" who will initiat the link.
So they installed a little software on the server (wich i heavely protested but hi, customer is king) so make this work. it works over TCP 5500 outbound.
Ofcourse, as always, isa server is blocking the communication (wich means tha isa server is working), but sometimes it is working to good.  And the soft-developers blaim it on the administrator.
 
I created several rules to (try) to make it work but no succes.
 
Anyone any tips and tricks ?
 
Regards,
Jo

you would probably need to create a 'user defined' protocol for vnc( tcp 5500) (btw are you sure it isnt 5900)

then you can create your rules to allow your custom protocol outbound. to increase security you could limit the destinations isa will let this protocol go to to this developers IP.

of course for added security, tell your developer to stop using VNC and get a proper remote admin tool, i can reccomend netviewer, as very easy to use and bypasses firewalls as it works over SSL.

Why not just use an SSL VPN concentrator?

You have an authentican layer into the network and can still use VNP or RDP over SSL to connect to remote systems in the internal network.

SonicWall, Netgear both make them.
Fortigate/Fortinet also have one inside a UTM unit.

I still use RDP or VNP, but use the SSL VPN as an authentican layer.
