VNC Problem

Duffman

Hey,

I want to be able to login to a computer behind a router with VNC or MS Remote Desktop from the internet. The problem is that I don't have access to the router config to forward traffic over the necessary ports to the computer... Result is that I can't connect using either client when I try the external IP.

Is there any way around this without having to config the router?

Thanks

Unless the router is forwarding all ports to the inside of the network, i doubt you will be able to connect. With VNC you could try changing the port that the client listens on and see if you are able to connect.

There maybe way to look at using port 80, i've seen some products that let you use that port but cant remmeber names off hand.

afaik for vnc to work you need port 5900 forwarding to your ip (this is on the default install the port it listens on can be changed in the registry as for any other aps that let you connect perhaps something of the trojan nature i know its a bit extreme but it might work.

TightVNC lets you change what port VNC listens on. That should let you through.

Wot jaden said .... pick a port that all routers pass ... 443 (https) is usually a good one.

oops ... just reread you original post. you may be stuffed, the router/firewall will have to forward ports to internal machines, if you dont tell it to forward port x to internal IP address y then you wont get anywhere.

Which won't work if the router is doing NAT though... trying to connect from an external source on that port will do feck all unless a persistent connection is already in place

I did assume however, that port 80 was open, and would allow connections through. Where it gets forwarded to is a different question.....

It's why I sold all my 3COM routers, and use Linux instead.

Real VNC can share using http:(port 5800?) (Java Viewer)

change the port in "display number"
5900 is default - the number entered is how far you are form 5900

and you can edit the port number by wraping around, but probably easier to just port forward anyway.
