Temporarily disable nftables firewall

Question

How to temporarily disable the nftables firewall?

Answer

To save the current rule set and disable all rules using nftables, you can follow these steps:

1. Save the current rule set to a file:

   # nft list ruleset > /path/to/your/backup/file.nft

   This will save the current rule set to a file in the NFT syntax format.

2. Flush all rules:

   # nft flush ruleset

   This will remove all rules from the rule set.

3. Verify that there are no rules:

   # nft list ruleset

   This should return an empty rule set.

To restore the previously saved rule set, you can use the nft -f command, like this:

# nft -f /path/to/your/backup/file.nft
