I recently installed buster on a Pi 3 Model B. Trying to setup a von (using
pivpn) I realised that
iptables is not working.
I've learned that there's
legacy mode and
nft. Here's part of the output from
hostctl and what I get when I run either version. I've tried updating and upgrading with apt.
Operating System: Raspbian GNU/Linux 10 (buster) Kernel: Linux 4.19.93-v7+ # iptables-nft iptables/1.8.2 Failed to initialize nft: Protocol not supported # iptables-legacy -L iptables v1.8.2 (legacy): can't initialize iptables table `filter': Table does not exist (do you need to insmod?) # iptables-legacy -m comment iptables v1.8.2 (legacy): Couldn't load match `comment':No such file or directory
I find it hard to believe that I am the only one experiencing this, but I really don't see anything helpful on the web (there are a couple of posts but no solutions). I was going to try to downgrade
iptables, but from what I see there isn't an older version packaged for buster to do that.
