Hi, I have two separate local networks which I want to connect together redundantly with a wired WAN and WWAN. On the network with the RUT241 I have setup the wired WAN port with the ip range 10.0.15.124/24, and the WWAN client as 10.0.15.125/24. Ideally, I would like to have the same IP address regardless of the interface, but I don’t know if this is possible. Whenever I send packets to, for example, 10.0.15.x I have been able to control which interface packets are sent on using the metric on the WAN page, but when I try to use the failover mechanism It doesnt seem to effect where the packets are going. What i’m wondering right now is if two WAN with the same subnet is is causing this problem? Is this setup possible to implement?
Hello,
It won’t be possible to assign the same static IP address to two different WAN interfaces (wired and wireless WAN), as that would cause an IP conflict.
Could you clarify what you’re trying to achieve? From your description, it seems like you want to control which WAN interface the traffic is routed through. If that’s the case, you can achieve this by configuring Failover/Load Balancing Rules rather than assigning the same IP to both interfaces.
The Failover feature is designed for fast redundancy – when the primary WAN source (in your case, wired WAN) goes down, the secondary WAN (WWAN) takes over. If this is your intended setup, then failover between two WAN interfaces with IPs from the same subnet is indeed possible.
Let me know if you need further guidance or have additional questions.
Best regards,
