Client behind corporate firewall

Post by siloseth »

I have a client behind a corporate firewall in a hospital environment. They are currently blocking all outgoing connections from this workstation except for 80 and 443.

Their IT department needs to know what port or port range to open up for UltraVNC SingleClick to connect.

Any help would be greatly appreciated.

By default, SC use 5500 (TCP) to connect to the remote host.

You can setup a NeoRouter (http://www.neorouter.com) to create VPN tunnel. Once you installed , you can specify the NeoRouter server listen port to 80 or 443 or what ever you need. On the client site, he may install a client as well. Then you guys can work just like in the same LAN. Thought the VPN tunnel, you can run VNC or any network applications.

Good luck
