I have installed NitroShare 0.3.1* on Ubuntu 18.10 and 0.3.4 on Windows 7. I can transfer files in either direction with UFW firewall off, but not with it on. I assumed that I needed to add some rules to UFW and tried this for the Transfer port

and something similar for the broadcast port 40816. The result is this

This works - but is it correct? I don't want to take any risks.

*The standard version 0.3.3 has a bug, it isn't related to security, it just stops the transfer.

An ArchLinux page says:

Basic configuration

A very simplistic configuration which will deny all by default, allow any protocol from inside a 192.168.0.1-192.168.0.255 LAN, and allow incoming Deluge and rate limited SSH traffic from anywhere:

ufw default deny

ufw allow from 192.168.0.0/24

ufw allow Deluge

ufw limit SSH

So I picked out

# ufw allow from 192.168.0.0/24

which I think should allow connections between computers within my LAN only. I'll now have to work out how to do this on the Windows computer.
