My only complaint is that coming from a networking background, Ubiquity’s OS is awful and makes me want to gouge my eyeballs out. It’s not very granular in how you can configure certain filtering settings, dual wan setups are difficult to manually change over, and good luck looking at logs to troubleshoot any traffic flow issues (hint: you can’t).

For someone who just needs a firewall and a VPN endpoint, it’s great. If you need anything more than that, get opnsense/pfsense.
