Wireguard VXLAN S2S VPN Single Gateway

[UserTom]

Hi,

VXLAN works great with Wireguard S2S, but I have one problem right now.
I have 2 identical gateway (Bridge) IPs on each router. The gateway is configured in Windows.

What is the best method to use a single gateway IP for clients?

Site 1 (BR 10.10.5.1) <--WG--> Site 2 (BR 10.10.5.1)
Windows clients GW: 10.10.5.1

When Site 1 goes down, the VM fails over to Site 2 with the same IP & gateway.
I think my current config may be causing problems. It is in fact a duplicate IP.
