Something isn't clear , i didn't find in the doc/faq a list of needed open ports for a basic virtualmin installation; I mean, i'm making my iptables rules, so in webmin->server->linux firewall , i made some rules;
When i run nmap , i saw some ports are open but they don't figure in my iptables rules..
port 21 is close in my iptables rules but nmap says open nmap says also : port 445/tcp filtered microsoft-ds , 111 rpcbind open ,587 submission open.
So questions : i never open or add rules for port 445 , 111 , 587 in my iptables rules..So if first politic is DROP , how is possible ?
Is vitualmin open thoses ports somewhere or in different place of iptables ? ( i use /etc/iptables.up.rules )
Whats the first rules -A INPUT -p tcp -m tcp --tcp-flags ACK ACK -j ACCEPT in default up.rules , i never use that before
Thanks , Jess
