Hi everyone

I would like to please for assist with realvnc. I have enterprise edition. Server is the PC, viewer is laptop. On both, I use XP. On laptop I have some firewall but i checked it twice and realvnc is ''enabled'' correctly. I also, on both computers, didn't forget about windows integrated (control panel) firewall. Also antiviruses are fine I belive. On the server I have SnoopFree but it allows realvnc. The problem is I cannot connect to the server (from laptop to PC). I get the message "Connection Timed Out". I went to the Server test page which is here:
http://www.realvnc.com/cgi-bin/nettest.cgi
but I got the message ''Connecting to port 5900 ... failed: connection timed out''.
As far as I know port 5900 might be closed but I don't know how to open it. I know for the server it can be used some other port instead of 5900 with no problem. Its easy to change the port inside realvnc's settings but I also don't know how to CHECK which port is opened and not used by some else software.
I have tried to open the port 5900 (in case if is closed) but almost ended before I even begun due not lack of knowledge with opening ports. All i know is I have to go here http://www.portforward.com/ and choose the router. My is NetGear. I think the model is RP614, at least it looks similar while googling it. So after I chose this router on the site, I also chose the software (in my case realvnc). Here is where my knowledge of port forwarding ends. It says ''To setup port forwarding on this router your computer needs to have a static ip address''. I have dynamic one but Im sure this is not the problem why I couldn't open the port. On the site I see it required router's username and password. I also don't know them. Tried to open the site http://<MyIPhere> but didn't work - not in firefox, not in internet explorer.

If someone could assist me, I would like to please so.

p.s.: Sorry for my English language - its not 100% correct.

Are these computer on the same network behind the same router? If so, port forwarding doesn't enter into the picture. If that's the case, you have a firewall issue between the computers, it's the only thing that makes sense.

No, it isn't the same network. Laptop is far away from the PC but still inside ''our'' country. But as I used to read, this doesn't matter in realvnc how far from each other are computers.

The distance isn't the issue, it's what's between the computers that's the issue.

From your description in the first paragraph, I suspect you're not actually forwarding the port properly. You need to go back to www.portforward.com and follow their instructions exactly for your exact make/model of router.

I don't use DynDNS due to security reasons. Everyone can view my IP through DynDNS. Its not safe. But I have programmed software (programmer programmed it for me) that sends IP on e-mail account. So I can check it from laptop (realvnc viewer).

If the availability of your IP address is a security risk, you need to deal that. hackers don't target a specific IP address, they simply scan a whole range of IP addresses looking for potential targets. You're going to a lot of trouble for no gain in security.

Hello? So could anyone try to help me with this? Been waiting for almost 3 weeks but got just one reply. My ip is dynamic. So how could i connect to the http://MyIPHere.com ?

Thank you for any help.
If you intend to connect to the machine via the internet then no matter how much you try to cover your tracks it has to resolve to your IP address.

You could make things a bit harder by using non-standard ports for VNC... i.e. 2293 or something else of preference.

Just make sure you allow the ports on your router as previously noted.

my suggestion is to dump VNC and start using something a bit more secure, a great program I use all the time and is free is http://www.teamviewer.com which is a remote desktop/VPN/file transfere program that creates a secure connection on both ends, no need to ever do any port forwarding with this either, seriously, get it, try it and you can thank me later! I can't believe people still use VNC, especially with default settings.

Cheers!

Jason09 i don't know how to do this thats why I am here. On the site port forwarding, I chose the name of the software and the name of the router which I ''think'' (at least it looks the same while using Google) its correct. Then I went step by step as it is described but cannot do first step already - it doesn't let me connect to http://MyIPHere

NeoPlosive I already remembered for non-standard realvnc ports. But as I have mentoined, I don't know which ports are available and free (not used by other programs) and not sure how to check this. I have never opened any port on my router. Is this possible in command prompt (cmd)?

Just make sure you allow the ports on your router as previously noted.
From the anti virus side of view and firewall ones (SnoopFree?) and even xp integrated firewall on control panel, everything is allowed. The only thing what can I remember that could be wrong is closed port.

Here's a comprehensive list of commonly used ports:
http://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers

Just think of a number you like and check it against the list, if its taken then look at what application already uses it, if you don't run it then you can generally use the port.

In order to allow the port past your router you need to log in to it. Go to http://www.portfoward.com for further instructions on this.

Once that is done go to: http://www.whatsmyip.com to find out your IP and try connecting to IPAddress:YourPort using VNC and see whether it works.

Ok, thank you everyone for your assist and your time for me. I haven't fixed my issue yet but it looks like I didn't know for the program PF Port Checker that you, Jason09, posted. Thank you Jason. I think and I hope with this program I should be able to fix the issue.

Teamviewer is good for some applications, but you fail to understand that UltraVNC offers end to end encryption. TeamViewer does not send encrypted traffic.
