Advanced users • Re: Moving Linux Kernel to 6.18

On debian, iptables is actually iptables-nft which provides a user-space compatibility shim that uses nftables from the kernel.

Code:

$ iptables -Viptables v1.8.11 (nf_tables)$ ls -al /usr/sbin/iptableslrwxrwxrwx 1 root root 26 Nov 20  2024 /usr/sbin/iptables -> /etc/alternatives/iptables$ ls -l /etc/alternatives/iptableslrwxrwxrwx 1 root root 22 Jan 27 11:40 /etc/alternatives/iptables -> /usr/sbin/iptables-nft

That sounds interesting! Will give it a go and report back.

Apologies for the delay in getting back. Been doing a lot of digging, but to no avail. My system does have the iptables stuff installed:which, if I understand what I've read here and elsewhere correctly, should provide what is needed. But it doesn't work. I'm getting to the stage where I think I'm going to have to rebuild the kernel from source - a very time consuming job on a Pi-400!
