I have two RV016 that works very well with a VPN connection . Two both routers have two WAN Internet connections (each one). The problem is when WAN1 fails (because the Internet fails) tunnel goes down, and the only way to fix this is if I change the WAN1 cable by the WAN2. Load balancing makes it perfectly, but I need when WAN1 fails WAN2 continue providing the service. Thank you.
