nftables alternative for iptables -F

Question

Simply, is there any quick alternative of iptables -F command (that just "deletes everything") for nftables?

Such thing wouldn't have much theoretical purposes, but it's usually a lifesaver for administration of bad/gone-wrong setups.

Answer 1

I believe you are looking for nft flush commmand. The syntax is:

$ nft flush table <name>

You can also flush chain:

$ nft flush chain <table> <name>

Alternatively you can always use nft delete rule command to delete any rules that you have just applied.

Answer 2

To flush the entire ruleset, including all tables and chains in one go.

$ nft flush ruleset
