Unless you need to share/provide services for a public, then you shouldn't be setting up reverse proxies or cloudflare tunnels in my opinion. All you need is WireGuard for you and the handful of users that might be using it.
I have two ports open for:
-
WireGuard
-
SSH Tunnel
Both of these services will only accept key based authentication.
WireGuard is the main way that my wife and me access the services away from home. When our phones disconnect from our home's SSID, Tasker automatically connects to the WireGuard tunnel so we never lose access to services.
The SSH tunnel is just a fallback in case I get behind a firewall that might be doing DPI and blocking VPN traffic. The SSH tunnel operates on 443 to hopefully appear to be SSL traffic and allowed through. I've used it a very limited amount of times to get out from strict corporate firewalls.
