If only one Public IP address is available, VXLAN can be configured through a VPN tunnel. In this case, an IPsec VPN will be used, where RUT1 acts as the VPN server and RUT2 as the client. The VPN creates remote tunnel endpoints, which can then be integrated into the VXLAN configuration to enable Layer 2 communication between the routers.

The configuration steps will be similar to those outlined in the [[#VXLAN over Wired WAN|VXLAN over Wired WAN]] section of this page, with the addition of IPsec configuration and adjustments in the '''Network > Devices''' settings, where the remote address of the created VXLAN interface will be updated to correspond to the VPN tunnel endpoint of the other router.
