Which ports is Virtualmin using?

Virtualmin

I’ve had to replace a physical firewall and want to open the correct email / web / etc ports for Virtualmin to operate. Is there a way to check and see which ports are currently in use? The Webmin IPTables firewall module doesn’t seem to be showing me everything. For example, none of the mail ports (25, 110) are listed.

Thanks!

Howdy,

It depends on what services you wish to use, but this is a fairly default iptables list looks like in Virtualmin:

ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:21 ctstate NEW ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:80 ctstate NEW ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:25 ctstate NEW ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:993 ctstate NEW ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:110 ctstate NEW ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:22 ctstate NEW ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:443 ctstate NEW ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:3306 ctstate NEW ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:143 ctstate NEW ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:995 ctstate NEW ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:443 ctstate NEW ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:80 ctstate NEW ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 udp dpt:53 ctstate NEW ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:587 ctstate NEW ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:20000 ctstate NEW ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:53 ctstate NEW ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 udp dpt:655 ctstate NEW
