For S2S connections with an active-active mode VPN gateway, ensure tunnels are established to each gateway VM instance. If you establish a tunnel to only one gateway VM instance, the connection will go down during maintenance. If your VPN device doesn't support this setup, configure your gateway for active-standby mode instead.
