Why do you need both addresses to be the same?  Why not reserve two consecutive IP addresses in the DHCP server?

 

I have various programs running that control the device via json-commands. Having 2 addresses means that every program has to try 2 json-commands for every action. That would be quite some reprogramming.

Yes, trying to assign the same static address to 2 MAC's already failed. That's why I thought of 2 static addresses routing one to the other but it may be a wild thought.

... to be more specific:

Normally, static routing is used on a network plane. In my case:

Network destination = 192.168.2.0

Subnet Mask = 255.255.255.0

Gateway = 0.0.0.0

Interface = lan

 

I was thinking whether this could also work for an IP-address, not a network plane. Something like:

Network destination = my device's WiFi-port static address = 192.168.2.191

Subnet Mask = ??, probably 255.255.255.255 ?

Gateway = my device's RJ45-port static address = 192.168.2.192

Interface = ?? 

 

Obviously I can try that myself but I thought this could be an issue known to the community and I found it an interesting subject worth debating.

 

By the way: I can easily solve the problem by disconnecting the RJ45-cables, thus forcing the devices to use WiFi on known static addresses. But I live in a heavily loaded WiFi-area and tend to use cabling where possible.

Great idea, hadn't thought of that.
