I have installed Virtualmin on a CentOS remote server, but it dose not seem to work

https://115.146.95.118:10000/

at least the Webmin page dose not work. I have opened those ports

http
ALLOW 80:80 from 0.0.0.0/0
ALLOW 443:443 from 0.0.0.0/0
ssh
ALLOW 22:22 from 0.0.0.0/0
virtualmin
ALLOW 20000:20000 from 0.0.0.0/0
ALLOW 10000:10009 from 0.0.0.0/0

And restarting Webmin dose not solve it:

/etc/rc.d/init.d/webmin restart
Stopping Webmin server in /usr/libexec/webmin
Starting Webmin server in /usr/libexec/webmin

And I have tried to use Amazon EC2 this time, still couldn't get it to work.

Since I need more than 10 reputation to post image, you can find the screenshots of the security group setting at the Webmin Support Forum.

I have tried:

sudo iptables -A INPUT -p tcp -m tcp --dport 10000 -j ACCEPT

It did not change anything.
