Hello, OpenWRT noob here. I have been trying to install OpenWRT on my old HP Prodesk 400 G3 mini. This will be a overkill router but i want to be able to run openVPN with high speeds. At first i was thinking abour running it a a "router on a stick". But i'm not shure if this will affect the speed of the internet because of sharing a single ethernet port.
Do you have a recommended setup solution?
I'm thinking about installing a secondary Ethernet port via the mini pcie.
Anybody got any experience with this and recommended model?
My main question i have is about the installation on a uefi system. The guide(https://openwrt.org/docs/guide-developer/uefi-bootable-image)is not not very noob friendly. I tried using a live usb and by using wget (latest stable Generic-ext4-combined-efi image) and dd i installed it on my nvme m.2. When i try to boot i get an error saying "Selected boot image did not authenticate", so i tried clearing the secure boot keys and that did not fix it. Then i tried disabling secure boot and i'm able to boot into openwrt.
Do someone have an easier guide to get uefi/secure boot to work or a workaround? So many questions...
Thanks in advance!
