I tried just using WIreguard and I struggled with with setup. When it fails to connect it’s really hard to figure out what the issue is (port forwarding on one of the routers? firewall on the server? something else?). WIth my netbird setup I’m also relying on DNS, groups and exit node setup. I think it’s just easier with a clear dashboard like the commercial tool have. Netbird is also free and I’m planning on selfhosting netmaker.
