The rules for public networks are very simple.
- Allow all outgoing traffic
- Allow related/established incoming connections. That is if your system
connects to a remote system and that remote system responds, it will
reply to your originating port or may also reply/connect to another port
on your system. You want allow those.
- If you have specific needs to receive multicast (such as mDNS) you
need to enable that for each case.
- Finally block all other incoming connections.
