Not exactly as data usually relays, but use a VPN if you are worried. Tbh people that raise this point are you not worried about other apps too? and already use a VPN?
Also are you not concerned ips are not being logged at the network level up stream from signal because that is literally what the NSA does
I'm sorry I thought hole punching bypasses VPN but apparently it doesn't.
You can use split tunneling if you want anything to bypass a vpn
Hole punching is for opening ports thru nat and firewalls
I can't completely visualize how it works with a VPN in the middle, or whether the VPN provider needs to (not) do anything to allow it to work. i just need to try it out.
The VPN just relays all your traffic including keet, keet is designed so you don't need to do anything for it to work, if you did it would be too difficult for people to adopt
Keet has a process of hole punching to make connections which is the key to its success and why they named the company holepunch
This is a great video on the tech and hole punching https://www.youtube.com/watch?v=QWWHKLyCFTU
There is connections that are more compatible with keet and they show as green in the keet profile page, there is yellow connections which require other peers to help but obviously still work
