The machine is a single laptop running Mint. All the docker containers are being served from this machine, and during this testing I was trying to access them all from that same machine. I observed the containers were up and running properly with docker stats cmd and I saw they were accessible over the original IP when using the ISP WiFi.
The access points are TP Link Deco, it’s 3 units, the first of which is connected via ethernet to my ISP provided router (Virgin Media Superhub). I believe they are WiFi meshing. I can’t tell too much more about how they work ‘under the hood’ as the setup was very… ‘consumer friendly’ and didn’t cover much technical detail
When I connect to this network and run ifconfig it looks like the IP changes in the last few digits. I thought if I used that IP with appropriate ports I might be able to view my servers, but that was not the case.
