I would rather just get a $100 brocade off eBay. Ubiquiti edge routers (at least four years ago) were nice but good god: don’t let them lose power. Fortunately, the router runs off a thumb drive, but when you are trying to fix a network that is in production and the FNG figures he can just power cycle it like Comcast taught him with his router at home… fml. Especially on a WAN (like ISP), it is a fucking nightmare. I have found Sophos and Netgate to be good solutions for small businesses, except setting VLANs on Netgate is a pain, but so is setting a VPN on Sophos. And Sophos is also a licensing bitch.
