Review on 🔒 Enhanced Network Security: ZyXEL Next Generation VPN Firewall with 1 WAN, 1 SFP, 4 LAN/DMZ Gigabit Ports [USG20-VPN] by Thomas Silva

I love ZyXEL firewalls, over the years I have installed literally hundreds of these devices at different companies, all different models and they are very stable and reliable. I even had a few lightning strikes and kept running. They'll last forever or until you decide to upgrade to a faster newer model. Keep in mind that these are very powerful professional grade firewalls that can frustrate the average consumer with minimal computer networking knowledge/training. If you know how to program business-class firewalls from SonicWall, Cisco ASA, Fortigate, etc., you won't have a problem.
