I was able to reduce that to just SSH by having my Wireguard host on a VPS and connecting out from home. Running SSH on 443 is a neat idea.
Running ssh on 443 doesn't do anything unfortunately. A proper port scan will still detect such a common protocol.
It's more about gaining access from inside a network that doesn't allow outbound on 22. For the web to work it would need 443 so connecting out on 443 might work
Sure, just don't mistake port switching for actual security.
I'm not missing any point. It should be clear to people who don't understand security that running a protocol on a different port doesn't mean shit for safety. "Because it doesn't get as much attention" wouldn't mean anything to any enterprise firewall the moment it's not an http header.
Absolutely. Though putting it on 443, which is regularly port scanned as well, is the opposite of security through obscurity.
Why not use Wireguard from your phones all the time, even at home? Just performance?
I don't know about your particular use case, but I've found that some apps experience problems when the IP address of a resource they're using changes out from under them. Like either they experience temporary connectivity issues during the transition or even just stop being able to reach the resource until restarted. However if your setup is working for you, that's great!
I'm confused why the IP address of a resource is changing for you when you're moving in/out of the wireguard tunnel? In my setup the LAN IP addresses always stay the same whether I'm on the local network or accessing remotely, It's just the route to them that changes (over a different ethernet adapter). Perhaps that's what you meant, or there's some crazy configs out there I'm unaware of.
I fully admit I may be doing this wrong. But in order to connect to a server over Wireguard I'm connecting to it over its Wireguard IP address. (And if I'm not connecting to it over Wireguard I don't connect to it over a Wireguard IP address.) It's relevant to note that I'm not using Wireguard as a traditional VPN where all traffic bound for the internet is tunneled over Wireguard. Instead, I'm using it strictly for point-to-point tunneling from a client to one of my servers. In other words, my default routes don't go to Wireguard. Maybe that's the difference here?
The app that comes to mind as having problems with changing IPs is the Home Assistant app. It would simply lose connectivity when the IP changed and never do another DNS lookup to connect again.. I always had to restart it. The "solution" for me was not to change IPs and just leave Wireguard on. It's cool that Ultrasonic handles it though.
Good idea!
