Setting up VNC behind router/firewall

[MaxDSP]

Ive got UltraVNC running on my home pc, and set my router to forward port 5900 requests to the pc running VNC. I cant seem to connect to it though; Im typing in the ip address and the port (xx.xxx.xx.xx:5900) but I get a cannot find server error in IE. I have my router set up to discard ping requests from the Internet, so would this possibly be a reason why I cant connect? Trying to ping my router from the Internet results in "Request Timed Out"

Port 5900 has to be opened through Router, and or Firewall, and or any other Port Blocker on the VNC Server Side.

I have 5900 forwarded to the LAN-side pc, is that the same thing as opening it? I was under the impression that it was. I'm also running ZoneAlarm on the LAN pc, but didn't make any changes to it. Maybe I'll take a look at it when I get home.

Thanks, Jack :beer:

Yeah Open Port - Forward Port usualy means the same.

However Zone Alarm is probably Blocking the Input.

You need to forward port 5800 to use the java viewer. 5900 is for the client app.

Well???!!!

Ultra VNC Viewer and Server BOTH are using by default port 5900.

If you can not use the VNC viewer, you can use Intrenet Browser. In such a case port 5800 is used, and have to be open throught the Viewing and Server Systems.

I'm not sure what you're trying to say, but you have to enable port forwarding of 5800 (default) to use the java viewer, which is what he's trying to do, but with the wrong port:

[/quote]I am not trying to Say anything.

Since the UltraVNC Server can be used in two ways (VNC Viewer, and a Browser). I am trying to clarify the differences in settings.

I usually open by default the 5800-5900 port range in the Router and the software firewall, so it is avaible for variety of Control purposes.

By using UltraVNC through the I.E , you loose some of the flexebolities of the remote Control. However it is a good thing if the Controlling computer does not have VNC Viewer.

Just type xxx.xxxx.xxxx.xxx:5800 (unlike the VNC viewer that defaults to 5900 you need to type the 5800 the browser).

Gotcha. I wasn't certain what you were saying. 🙂

FYI, forwarding the 5800-5900 port range instead of 5800 and 5900 explicitly can crash some soho routers when you connect to the system the ports are forwarded to. I've experienced this with Netgear and some SMC routers.

Thanks for tip. Copied and pasted into the Data Base.

I usually control few computers with VNC.

In order to make it easy I usually assign: Computer 1 as 5810, computer 2 as 5820, and so on. Keeping the Band open makes it easy to maintain the system
