Linux friends - I have a networking question. Can I give my server two network connections but only allow Internet access from one of them? All my IoT stuff is on a segregated 2.4GHz WiFi network. My server is on a segregated Ethernet. I want my server to talk to devices on WiFi. My router doesn't let me punch a hole between them. If I stick a WiFi dongle in the server, how would I tell it "talk to the WiFi LAN but don't use WiFi for Internet access"? Ubuntu, if that makes a difference.
