* Put the firewall in force.
* 113/ident — Allow identd to be reached, probably all my hosts run it for
IRC.
* If some host doesn't run it use `ufw reject 113` so the IRC server
asking for your ident is replied "Connection refused" and the
connecting happens faster as you aren't force to wait for timeout.
* I am not sure if this is faster than running ident, but my
recommendation is to allow it if you run it and otherwise reject.
Deny forces you to wait for timeout as your firewall says
nothing.
* 631/cups — Allow access to cups for printer sharing
* 5060/sip — VoIP, in this case Linphone
