I have 2 links, one main, and one backup LTE link and persistent openvpn connection.

When main link goes down, opnsense switches to LTE, VPN reconnecting and all works fine, but on main link recover i have openvpn connect over LTE link. So, then question is, how to drop vpn links, and all other links on LTE interface when main link goes up.

Did anyone tried this board with 20.1? http://www.banana-pi.org/r2.html

The patch worked for me and I know now why the connection dropped every time.

I had "Firewall: Settings: Advanced: Dynamic state reset" active (Reset all states when a dynamic IP address changes.This option flushes the entire state table on IPv4 address changes in dynamic setups to e.g. allow VoIP servers to re-register.)
But the IP didn't change, so this trigger shouldn't have been triggered.

I have tried this patch. But without success, i have incoming connection block, not just drop, after every "IP change".

Finally... Fresh 18.7.10 setup, restore configs from backup, and i have working router...

I think you are onto something here.
Upon renewing the WAN IP, connections get dropped, and VPN as well as dpinger and sometimes NTP die :-/

It's strange, for example i have static IP from my ISP, but! It should be requested over DHCP, and it works fine over the year on 18.* series.

I'll try to check newwanip script today evening...

After 10-20 minutes of uptime all incoming connections are blocked!

So, OpenVPN tunnels are dropped too, it was fine on 18.7.10 is it possible to downgrade may be?

19.1 seems to be very unstable
