Nftables usage
From wikinotes
Info
You can create tables/chains/rules on the commandline, but it's way more readable to write a file.
You can even split your rules withing multiple files and source them.nft list tables # list tables nft list table 'inet' 'my_table' # list chains in 'inet' table 'my_table' nft list ruleset # list all rules nft describe <expression> # get info about reqd types
Validating Rules
sudo nft -c -f /etc/nftables.conf
Clearing Rules
Clear all Rules.
Add this to the top of your nftables file to flush rules every time your file is loaded.nft flush rulesetnft flush table 'table_name' nft delete table 'table_name'
