Hello,

For your use case, I would recommend using iptables. You can insert custom iptables rules by navigating Network > Firewall > Custom rules.

There is a comprehensive guide about rules which should help you to come up with the required rules: https://www.howtogeek.com/177621/the-beginners-guide-to-iptables-the-linux-firewall/
