Ok I am stumped. I used port forwarding on my Netgear rp614 router. But when I try to verify the port through GRC sight it tells me it is stealth. I know that the problem is not the router since I tried it on another computer and it works fine, port is opened. Both systems have winxp sp2, they both have the same virus checker and both have windows firewall turned off. So why am I getting stealth mode on one computer and opened port on another with same router. I need these ports opened in order to use VNC. Thanks in advance
Ok so you have told the router to forward incoming connection requests using a particular port to a particular PC. Next you will want to check that that particular PC is actually listening for the connection. To do that get a command prompt and type netstat -an In the local address column look for the particular port. The state column should show it listening. You may find it easier to use this
the port is listening and if it is definitely correctly forwarded in the router and you still can't connect from outside then it is likely that you have firewall software on the computer which either needs to be removed or properly configured to allow the connection. If this is XP with the built in firewall turned on then you will have to configure it to allow the inbound connection.
I tried tcpview from and it shows winvnc.exe:192 as listening Here are my latest tests: I rebooted into safe mode, shieldsup gave me the port as closed. Ran TightVnc, ran shieldsup port is opened. reboobooted into regular mode. Ran msconfig disabled all startup items, disabled nod32 (virus software)service from services tab. rebooted went to task manager did end process on a few more items. Ran shieldsup and is still stealth. ran Vnc still STEALTH. Tried removing my router and connect direct, and everything is still stealth. Besides windows firewall which is off what else can be causing everything to be stealth? This is a quite new winxp install, therefore not much junk has been installed and removed. It never had anything like zonealarm installed. Is there some software out there, which I can use to see what file or service is blocking these ports from my computer? Please help......
It is not necessary to go disabling startup items unless they really are things you do not want. It is also not necessary to go disabling services unless you are sure that they are not necessary. Please put the router back and since this is a new XP install go to
and check that all critical updates are installed. When you've done that go to the control panel, add/remove programs, and uninstall any firewall and anti-virus and other security software found there. You can put anti-virus software back later. Next make sure that the XP firewall is turned off. Make sure that your Internet connection is working and run vnc. Use TCPView to make sure that vnc is listening. Use ipconfig /all at a command prompt to make sure you know the correct LAN IP address of the PC running vnc. Configure the router to forward the correct port(s) to the PC running vnc. Next do this
ask yourself why none of the sites found there mention port 192 but many of them do mention 5800 and 5900. In particular 5900. When you've got it working, check the PC with
Ok finally fixed the problem after hours or troubleshooting. I figured it out by removing all services which are not from windows, and finally found that when the sevice from cisco vpn cvpnd.exe was running that is when I got the stealth mode. After further investigating I noticed that in the VPN client options there was an option called "statefull firewall(always on)" by removing that little %&^% checkmark whamo everything works great. Thanks to all who helped and hopefully this will help others.
