Hi all,
I want to transition the subnet IPs of my LAN from 192.168.1.0 to 192.168.2.0.
In preparation from this, I have assigned a secondary address in the 192.168.2.0 subnet to the bridge and I have manually assign an IP in the same subnet to a test machine.
To my surprise the test machine in the new subnet cannot access the Internet. I can ping the router on the secondary address though. It seems for some reason the router does not forward the traffic from this second subnet.
I can’t see what’s wrong in my config, could you help?
