Preamble So, why build a firewall with Proxmox as a hypervisor and not install bare-metal directly? Well, i ran OPNSense bare-metal for years on a Sophos XG105. It was stable and running fine. The Sophos also had an usb serial port, which was very useful for console access. Unfortunaly, the system began to show its age and performance was not sufficient anymore. When there was a lot of network traffic on other VLANs, I had intermittent packet loss and lag spikes in video and voice calls. I tried to spread out the VLANs on all interfaces, but it only helped marginal because the CPU was the limiting factor. Also the ports were only just 1000BASE-T, meh. ...

For testing purpose i have an old Fritz!Box 7360 flashed with OpenWRT. For $reasons I needed to reflash the original firmware. Unfortunaly the Recovery tool didn’t work with my model, because it used to be provider branded by EWE. There is a rebranded Version of the tool by EWE, but this didn’t work either. So i researched a little and it turns out you can flash the firmware manually via the ADAM bootloader, just like OpenWRT. ...

Recently I moved and need to rethink my rack and network solution. Previously my server and the main switch lived in my IKEA Oppli TV-Bench, which was already showing its age. I used a Mikrotik CSS326-24G-2S+RM which is a very capable switch for the price, but unfortunaly don’t have PoE (For 120€ also a little too much asked). (At the time) my only PoE device was my Ubiquiti Unifi AP AC Pro which I powered via the included injector. Not an ideal solution, but it worked. As my hardware only stayed in one room, this was enough. ...

About a year ago I replaced the horrible TN display of my boyfriend’s T430 with a Full-HD IPS and in the same move I replaced the LAN Ethernet USB Board due to a bent USB port. Because the laptop had to be completely disassembled anyway, I decided to give Coreboot a try. This blogpost serves as a memory support, if I should decide to flash another laptop. I’ve used a CH341A programmer. Unfortunately I did not take any pictures, but you should find some in the linked blogposts below. ...
