THANK YOU! Now where do I put this FILE.conf? I would like for it to run everytime I turn on my computer.
I wrote "FILE" in caps trying to express that you can choose any name. Debian has /etc/nftables.conf and nft supports the "include" directive, see nft(8). So you may put your file to /etc or to create a dedicated directory, e.g. /etc/nftables.conf.d, for your settings and include your file from the main conf file, so it should be applied on each boot by nftables.service. You may put "table ip shared ..." content directly into /etc/nftables.conf as well, however I prefer to minimize changes in files provided by packages when it is possible to use additional ones.
Instead of installing dnsmasq you may specify a public dns server in your router settings (8.8.8.8, etc.). Or if you are sure that DNS configuration provided by the upstream router 192.168.0.1 is stable then you may use servers from DHCP lease. However having a local caching DNS server (dnsmasq or systemd-resolved) should not harm.
By the way, since you have dnsmasq running, you may enable its DHCP server (dhcp-range=192.168.231.5,192.168.231.254) and may switch mi router from static network configuration to DHCP.
As a final note, NetworkManager allows to create "shared" connections (ipv4.method). It starts dnsmasq and adds necessary firewall nat rules. I used it in both directions: with ethernet upstream connection to share wifi or to leverage 1G ethernet link to copy files between laptops while one of them has an active wifi connection.
