How it work through NATs?
- snvzz 6y agoIt implements hole punching.
- zajio1am 6y agoHole punching works for firewalls, but is unreliable for NATs. Note that most home routers are Linux based, and Linux uses symmetric NAT, where hole punching does not generally work reliably.
- snvzz 6y agoIt also implements relays, if both sides can't be reached. And it works with TCP, if it can't be made to work with UDP. And it supports ipv6. You're pretty much covered.
- namibj 6y agoIPv6 fixes that for those cases where you have too much NAT on both ends.
