I upgraded my WRT1900ACS from 21.02 to 22.03.2. I can't see any firewall rules:
root@router:~# iptables-nft --list
# Warning: iptables-legacy tables present, use iptables-legacy to see them
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
root@router:~# iptables-legacy --list
-ash: iptables-legacy: not found
I have some custom rules but they are all in /etc/config/firewall, so I understand the syntax should carry over from fw3 to fw4 without change.
I don't understand why it's saying iptables-legacy is there when it isn't.
