KVM auto iptables rules

[kalpana]

Hello

I have virtual machines running on Ubuntu 22.04. I suddenly saw the default iptables rules arrive this morning. These rules cut off all internet access.


How can I turn off these firewall rules? I don't know why it came on automatically. I'm not running anything like Hooks. I already have my own iptables rules. I have more NAT rules. I don't have any filter rules.


How can I prevent firewall rules from coming automatically?

Thanks.
