commands are:

iptables -I INPUT -p tcp --dport 3389 -j ACCEPT > to open only that tcp port

sudo ufw enable transmission > to open the whole program

being a newbie I’d say it’s safer to only open a determined port with iptables. What do you think?

    A big thing the other comments are missing is that just running the iptables rule only works for the current boot. You need something to rerun it every restart

    ufw is a front end to make it easier to use them

    If you want/need more control, you should look into /etc/iptables/rules.d config files

    Edit: or depending on what your distro already has, the firewalld comment makes a lot of sense. E.g. that’s Fedora’s default front end
