1) Have you also opened those ports on the server's firewall?
2) Are you sure that the VNC app you are using is configured to listen on those ports?
3) Have you tried opening the ports on UDP? I mean opening both types, TCP & UDP.

I don't know what OS are you running on your server, so I'll tell you how to do it in Windows: go to the Control Panel and check the Firewall option.
To know on what ports is the VNC app listening just go around its options.

hi brother i dont think so that i need to any thing on the server bec it was working fine with old router but since i instal the new router its creating problems.one thing more after opening ports on router i can access my server frm inside of building through putting our static ip address..
but i dont know why i cant access it from out side. and as you said to me go to control panel and open fire wall.
when i try to do this this message comes out.
'windows firewall cannot run because another program or service is running that might use network address translation component (IPNAT.SYS)' after cliking firewall this message comes out..
any way thx alot for your previous replies i wating for your next reply thx..
regards
umar
