VNC Viewer to a virtual CentOS 6 fails when iptables is enabled
 

Hello:
On a Virtual CentOS 6 (2.6.32-71.el6.x86_64 ip address 198.4.173.153). I installed tigervnc and tigervnc-server; update iptables, create VNC password, and issue vncserver :1 to start it up.
# service vncserver status
Xvnc (pid 1811) is running...
# iptables -L
…
ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:ssh
ACCEPT tcp -- anywhere anywhere state NEW tcp dpts:vnc-server:5902
…
From a Window laptop, VNC Viewer to this VM fails (198.4.173.153:1).
“Attempting to connect host”
“unable to connect to host: A socket was attempted to an unreachable host. (10065)”
If I stop iptables on the VM, VNC Viewer works.
Similar VNC configuration on other physical CentOS servers are working fine with iptables enabled.
Thanks.
Warren

did you checked your firewall if it is listeing to vnc port no. as it is not fixed to 5902
