I have a RUT200 with two connections. Wired that goes to a fiber router and cellular as backup.
The problem I have is that when the fiber fails and goes to cellular, it doesn’t always switch back automatically
The fiber connection has a public IP when it works and when it fails, it gets 192.168.0.2 from the fiber router. When that happens, I need to go into the RUT200 and switch the fiber interface on and off, then it gets its public IP. I do have flush enabled on both connections.
Thank you for the update. Could you kindly provide a screenshot from the Network → Failover page? This will help to further investigate the issue and ensure everything is configured correctly.
