 I've been testing this NETGATE 4100 now for about two weeks. It's currently running Sericata, PF Blocker, OpenVPN, and WireGuard, but still the memory usage is only about 48%, granted there's only a couple clients behind it. One of the things we do in testing is running a series of data tests over the VPN so we can see how it loads up the processor and how the system handles it if there's any disconnects, drops, or if it just keeps on working, and so far it's been going great and kept on working. Here's a look at all the Sericata alerts because I have not spent any time tuning it and a default install Sericata is going to get a lot of alerts when you're doing things like speed tests over VPN. To give you an idea, I've so far run about 40 gigs of data over the VPN to make sure we're testing it thoroughly. My next test will be with WireGuard and once that's done I'll get the full video posted and the review done. Let me know if you have any questions or comments, leave them down below.
