Question unable to connect vnc server over Internet

On the server having live ip address, I have installed vnc server using:
yum install vnc-server
yum groupinstall "X Window System" "GNOME Desktop Environment"
yum install xinetd vnc-ltsp-config
/sbin/chkconfig xinetd on
/sbin/chkconfig vncts on
/sbin/service xinetd restart

On my local machine connected to internet via LAN, I have installed vnc viewer using:
yum install vnc

When I connect to the vnc server using
vncviewer ipaddressofvncserver:1

it shows
unable to connect to host. No route to host (113)

Indeed you should not turn off the firewall. You need to read up on tunneling vnc through ssh. That way you only need to open the ssh port.

Here's a simple guide.

If you google for it, you'll find many more.

Nice one.

Now localhost is working on that server (having live ip)
But when I try to connect from local machine to liveipmachine (using http://liveipofserver), it is unable to connect.

nginx is installed on the server machine.

any help regarding that ?

(By the way, when I did "/sbin/service iptables stop", local machine was able to connect server. But as you know I don't want to do "/sbin/service iptables stop"


centos, internet access, vnc, vncserver, vncviewer
