So is the issue that CentOS 6 sets up firewall rules that the Webmin installer doesn't open up port 10000 on? That should happen automatically .... are you using FirewallD, or just plain IPtables?
from virtualmin-install.
I installed CentOS 6. Ran install script (pro version). Then I couldn't access my virtual machine. After stopping iptables the problem was solved.
from virtualmin-install.
I have installed it nearly hundreds of times. It never happened on other CentOS versions. Never happened on Debian and Ubuntu.
from virtualmin-install.
Did you happen to capture the firewall rules that were active before stopping IPtables?

[root@debug-centos6 authentic-theme]# iptables -S

To compare:
CentOS 7:
[root@debug-centos ~]# iptables -S |grep 10000
-A INPUT_direct -p tcp -m multiport --dports 10000 -m set --match-set fail2ban-webmin-auth src -j REJECT --reject-with icmp-port-unreachable
-A IN_public_allow -p tcp -m tcp --dport 10000:10100 -m conntrack --ctstate NEW -j ACCEPT
-A IN_public_allow -p tcp -m tcp --dport 10000 -m conntrack --ctstate NEW -j ACCEPT
CentOS 6:
[root@debug-centos6 ~]# iptables -S |grep 10000
-A INPUT -s 192.168.122.0/24 -p tcp -m tcp --dport 10000
-A INPUT -p tcp -m multiport --dports 10000 -j f2b-webmin-auth
-A INPUT -p tcp -m tcp --dport 10000 -j ACCEPT

CentOS 6 is EOL.
