To no one's surprise, the slop machine can't help but spit slop, so I have exhausted my knowledge of networking and I hope I can find some help here. I have a proxy container in a container network let's call it for example's sake: 10.0.0.2, it has a gateway at 10.0.0.1. My host is connected to the LAN, let's say for example's sake as 192.168.0.2 and gateway at 192.168.0.1, and I need to reach a service at 192.168.0.3. Because it's relevant later, it's a Fedora 44 server with a standard firewalld setup. In order to isolate where the issue lies, I checked all the connections along the way, container can reach gateway and host can reach container, host can reach the LAN service and the only "broken" connection I can see is the container directly to the LAN service. Thus I conclude the issue is within the host, somewhere between the container and the LAN, within the host configuration, and not somewhere on my LAN.…
