That depends on how you are using them. You can have two interfaces on the same subnet. That often happens when you have wired and wifi active at the same time.You must use different IP range for each ethernet ports, like 192.168.0.0/24 for port 1 and 192.168.0.1.0/24 for port 2
I agree but the given use case is not the same here :Code:
3. Now my Inbuilt Ethernet port is configured for the Server and USB to ethernet converter port is used connect he raspberry pi.
Which is still open to interpretation. And both interfaces could still be on the same physical and logical subnet.
We need to see the logical and physical network diagrams. I wonder which iof the following is closest to the OP's physical network:
Code:
server ---- pi ---- something elseorserver -- network switch | | |pi eth0 --- | | | |pi eth1 ------ | |something else --orserver -- network switch | |pi eth0 --- | |something else -- |Pi eth1 -Statistics: Posted by thagrol — Sat Jan 17, 2026 4:21 pm
