Problem:

I have a laptop and a server (Home-Server) with fc17. They are both using the desktop environment. I am trying to set up a VNC server on Home-Server so that I can set everything up without having to sit in front of it for everything.

I have tried using the VNC server software included in the distro. and I have tried using TigerVNC Server. I can't get either one to work. When I scan the ports of my server using my laptop, it quickly stops and shown nothing. So I disabled the firewalls on both systems and forwarded all ports to the server on my router. I still cannot find any open ports on my Home-Server.

I am at my wit's end. Please help me find out why I cannot find any ports on my server.

Note: I can see the ports that are open on my Windows system.

Note: Router has OpenVPN Server enabled.


Scenario:

Server: Fedora 17
Notebook: Fedora 17
Router: WNDR3700v1
Router Firmware: Gargoyle v1.5.8


Output from "iptables -L":

Just to make sure that basic connectivity is there: can you PING the server from the notebook? And how is the windows machine connected? – tink Nov 5 '12 at 22:19
Yes, I can ping the server. The server and Windows system are connected via Ethernet cable. – ITman Nov 6 '12 at 2:17
And the reference to "I can see the ports" above; is that ANY ports, or the VNC port you are hoping to see? – tink Nov 6 '12 at 2:29
I just checked again, I can no longer see any open ports on my Windows computer or my server from my notebook. – ITman Nov 6 '12 at 6:32
OK ... what is the output of iptables -L on the server? – tink Nov 6 '12 at 19:02
