I'm now upgraded to 22.03 on an Archer C7 v2. Of course the system is crashed, the most settings is not working, i'm repair most of that. But...
I have 4 openvpn clients, and before the update worked perfectly. Now the clients connect and the hosts is reachable from openwrt. but not from the LAN. I deleted the interfaces, firewall rules, sections, recreate them, enabled the forwarding, but still no forwarding.
What is wrong?
After the upgrade, the wan interface's forwarding died too, But a full recreate the interfaces, and firewall sections, then is working. This on the openvpn interfaces is not a solution.
The nftables isn't working good, or somehow insulted by the iptables rules.
I'm not uderstand if the iptables changed to nftables (or any big change) the updater process why not archive original config file and put a working new? (or convert them a working one) i need after upgrade some config files remove by hand to working final result.
