A few weeks ago Rayfish was released and only worked on PCs. But today I checked and noticed V2 was out. I updated my V1 on my PC and then installed it on my phone.
I had to restart the network on my PC to refresh the VPN networks I had already created. I setup a searcXNG on my PC just to try some sort of server. Next I created a firewall rule for that port on the rayfish network and another rule for the network on my Linux firewall. On rayfish I created a network and an invite code for my phone. On the phone I entered the invite code and was immediately connected. I could then ping from my phone to my PC and viseversa.
Finally I searched for the PCs rayfish IP and just connected to it on my browser on the phone. That worked and I was happy. But then I turned off my WiFi on my phone and clicked refresh… A few seconds later the phone re-connected and I got to my searcXNG!
My outside IP is not fixed and I rely on Cloudflare. But none of my services are actually public and are not planned to be public. So now with rayfish I get a permanent IP for free regardless of what my actual IP is. The possibilities are endless… Big big!
This is very cool! Yeah it’s AI developed, but this is AI for us. It’s clear and well defined for me, AI working for us is small potatoes vs AI the evil resource sucker spy tool. So let’s take advantage. Specifically this project is great and solves my privacy issues with Cloudflare.
Bug Maybe I’m putting it too simply. Any thoughts on this?
So what, this is just yet another app that makes a VPN connection to your home network, but AI-coded instead? Why not use one of the non-AI made solutions?
Because this one has no central server.
Neither has a wireguard tunnel into your home network, you host the WG server on your own computer (or router even, that’s what I do) and just point your clients to that using either static IP if you have it or a DDNS service like the cloudflare you’re using if you have a dynamic IP.
I guess I’m wrong. Wireguard can be p2p and that’s exactly how most users use it so it’s super easy to setup that way.
Anyway, this ray fish thing is just impressive that’s all.
This is flatly incorrect
WireGuard still needs a central server that you don’t control.
No, it really doesn’t
Lolwhat, no it doesn’t…? Did an AI tell you that?
You spin up a Wireguard server yourself (or use the one in many routers), point clients to that and be happy. The only “other” server in that chain might be a (Dyn)DNS resolver, and you could even self-host that one (and therefore also omit Cloudflare).
Oh so it doesn’t do dynamic changes in IP like rayfish does within a few seconds?
That’s not rayfish handling that but the cloudflare DDNS you’re using that handles that. So yes, self hosted WG server handles that just as fast.
If you’re talking client-side, it will reconnect as fast as whatever internet connection you’re switching between allows it. For me it’s something like 3-5 seconds from disconnect to reconnect.
No, actually rayfish creates a tunnel network such that cloudflare is not needed for self-hosted things like immich or navidrome. You can connect to those by the IP overlay from rayfish or its hostname also created by rayfish. If your phone or home IP change, the actual overlay IPs stay the same. The two devices reconnect otheir own. So truly Cloudflare can go pound sand and report the 30,000 hits it protected me from AI. Ofcourse I guess I could use their DNS to keep a searchable FQN AA record.
