I can also say that IPFire, even though logically I am still on the Green Network, I am not fully in Green or my entry upstream wouldn’t be black in the color scheme. Since my logical network on Wifi is upstream from my switch, I assume something may be getting blocked on its way back to its origin, but I had thought requested traffic from point A to B, if it makes it, would be stateful on the way back. The Options in the IPFire firewall can be confusing. I have been about 8 straight hours with hands on keyboard, ssh, and pondering wth may be going on with this. I can say I have a ton of traffic crossing that segment successfully, but apparently I am missing something basic here. I then jump to SSH on PiHole at 172.x.x.165 and I can see the traffic arriving…however the return traffic never crosses IPFire on the way back across the network segment. I run tcpdump -XXnni any on the IPFire SSH and I can see inbound traffic heading to the PiHole. ![]() When I jump on any other computer in my logical 10.x.x.0/24 network segment, I can’t hit it with SSH, ICMP, HTTP or anything else successfully. Fully functional might I add… except for 1 thing. I can get to PiHole from any computer in the 172.x.x.0/24 network, at its Web UI and it loads, browses and acts absolutely normal.
