Can I get some recommendations for a router/firewall friends?! - eviltoast

Hi, I’m currently running OPNSense on an HP T730 mini pc. It’s been working very well for a few years, but now I’m upgrading my internet to 2.5g symmetrical and also plan to do some more complex routing.

So I’m looking for any recs for a small (max 12" squared) mini-pc or similar device for use with OPNSense (or similar).

I have a 10gb SFP PCI card in my HP T730 so I’d like to keep 10gb SFP (my switch is also SFP based).

I want to toy with Wireguard, and also have VLANs. If that changes anything.
