udp2raw is a tunnel which Turns UDP Traffic into FakeTCP/ICMP Traffic by using Raw Socket, helps you Bypass UDP FireWalls(or Unstable UDP Environment).
Some ISPs are not friendly to UDP traffic, especially when I play game streaming over ZeroTier, like this :
udp2raw can Send/Receive UDP Packets with ICMP/FakeTCP/UDP headers that can help you bypass UDP blocking, UDP QOS or improper UDP NAT behavior on some ISPs. And the document said
NAT Support All of the 3 modes(FakeTCP/UDP/ICMP) work in NAT environments.
So is it possible that make end-to-end traffic over udp2raw?
On the other hand, UDPSpeeder also can improves the Network Quality but in another way. if can use both udp2raw and UDPspeeder that will be great !
