HI @andrew06074, welcome to the Streamlit community!
I’m slightly confused about your approach here. If you add two NICs, wouldn’t that create two separate networks?
If you want to run two different apps on different ports, you should be able to do it on the same network, by passing the port as a command-line parameter:
