Port range 10000:10010

I noticed that when setting up the firewall through virtualmin, and you choose “setup for virtual hosting” option, a range of 10000:10010 rule gets created for access to webmin/virtualmin. Why is this a range? In the webmin config port settings I don’t see options to set a range and only a single port.

While port 10000 is what’s used to access Webmin/Virtualmin via a browser, I believe the ports up to 10010 are used for Webmin RPC calls.

An example of when that would come into play is when setting up a DNS slave, where Webmin would transfer zone setup information from one host to the other.


Thanks Eric… I understand. Just dug around based on your comment and found the below for anybody else with a similar question about this port range and RPC:
