I have an Ubuntu 18.04.6 home server, connected via wifi (wlp2s0) to the internet. It has ip 192.168.1.13 on the local home network.
I want to connect a wired ethernet camera, that has a fixed ip of 192.168.1.99 when connected to the router. Now, I'd like to connect this camera to the home server via LAN (enp0s25), assign the camera ip 192.168.1.99, and share this camera over the wifi.
The connection works when ethernet is disconnected. When I connect the ethernet cable (between server and camera), though, I think the computer tries to connect to the internet through eth and internet stops working.
Only selecting "Use this connection only for resource on this network" for eth as suggested here does not work.
I followed the instructions here, and it would not work: the server either sees the camera, or is visible through the network, but never both. Then I figured it might be a priority issue and lowered the priority of wlan as suggested here. However it's still not working as I'd like it to.
Any other ideas please? Many thanks for your help.
