Wireguard Issue with multi WAN

[hamidsattarrana]

Hello there!
I hope you guys are well.

I have a requirement in which I have to configure wireguard tunnel with headoffice and I have to send all traffic including internet traffic to headoffice via wireguard tunnel.
Also I have to configure failover of this wireguard tunnel between 2 Internet connections.

I have configured pfsense as a wireguard client and wireguard server on headoffice.

Issue is that I have lots of deny traffic in logs. And sometime it works and some it does not.
Most of the time it happens when ISP goes down and tunnel shift to another?

I have read some documentation that wireguard is experimental and under development?

Do you guys have any solution?

My requirement is 2 tunnel with 2 ISPs. 1 tunnel will go to Newyork another one will go to London.
And in my local site I want load balance between those tunnel. And if 1 ISP goes down I want to shift all traffic to the backup ISP.

Thanks.
