So current setup being the Cloud Gateway Ultra, 2 cisco switches, and the flex switch.
Setup is running very well for what I'm doing with it for now, and is a big improvement from the previous iteration. It's not running all the automation and networking stuff I want to add, but that's down the line a tick yet.
Aside from equipment, the biggest change I've made with the new, transition phase, setup is having moved from self-hosted DNS, over to using NextDNS. I have a profile setup for my private, IoT, and guest networks, and am running the cli version directly on the router. All requests go through it, and it's been excellent. I have it tweaked to about where I want it, and have only had to add maybe half a dozen urls to the allow list. It does add a tick bit of latency when it's has to fetch a non-cached domain, but it's not bad. Just barely enough to notice, and it's not distracting.
Second biggest change was separate guest network. Previously I just put company on my IoT network, but this works out better, and allows for a separate DNS profile from IoT that has different settings and block lists in use.
I've also picked up a mini pc (geekom, 1T, 32G, Ryzen 7) about a month ago, that I'm messing with as a desktop for a bit. It will end up being one of my container servers in the long run. Not sure how I'm going to use it specifically, but either as part of a k8 cluster or a proxmox box with a few specific network containers, then a few n100's for home lab stuff and local development.
Right now I have a small windows 11 partition, since it came with it (although I reinstalled from scratch), and Kubuntu on the main partition. Haven't used the windows partition really, but have it just in case. I will dump that partition before long, and once I have a container environment setup, I might think about setting it back up for browser testing. Other than that, no real use for windows. It's pretty easy on power, which is nice, and seems to be holding together well. I do have an external fan (USB, AC Infinity) blowing air directly into the bottom to help in case of any heat issues.
Fun little gadget so far.
