I'm working in a small company (7 employees) and we need a new router or firewall for both our office and our servers in a datacenter. We have a 1 Gbit/s synchronous internet connection on both sites. We currently have CISCO ISA 570 on both sites but those are not performing very good and they do random reboots.
Now we're looking for a new firewall or router. We don't need things like anti virus or web application firewall. So I'm wondering if we need a firewall anyway or if we can just buy two new routers. I'm thinking of a Ubiquiti EdgeRouter Pro vs. Sophos XG210. Since we would like to connect both sites via VPN, we would like to buy two devices, so the price does matter.
