What is PureOS Byzantium's default firewall and rules?

PureOS (L5’s operating system, which is based on Debian where they used to use iptables, but now) uses nftables.

As for the defaults, I’m not sure, as I don’t have them left anymore (all kinds of edits over the years). Check to see yours with sudo nft list tables and then sudo nft list table <name of table, like ip nat>.
