uTP on IPv4

[cpacia]

Don't know if this is a problem with my machine, but I can't seem to get it to listen on external uTP IPv4. /ip4/73.89.130.237/udp/4001/utp is never listed in the swarm addrs.

Config:
"Swarm": [
"/ip4/0.0.0.0/tcp/4001",
"/ip6/::/tcp/4001",
"/ip4/0.0.0.0/udp/4001/utp",
"/ip6/::/udp/4001/utp"
]

Addrs:
Swarm listening on /ip4/127.0.0.1/tcp/4001
Swarm listening on /ip4/127.0.0.1/udp/4001/utp
Swarm listening on /ip4/192.168.0.11/tcp/4001

interesting... good catch. This might be part of an underlying NAT issue.

encountering the similar problems building a private network using .ipfs/swarm.key

tried with the same swarm config; but not even seeing IPv6 UTP:

also tried with the following, without TCP; not sure if it is due to my network settings:

Config:
"Swarm": [
"/ip4/0.0.0.0/udp/4001/utp",
"/ip6/::/udp/4001/utp"
]

We don't currently support /utp anymore, you'll have to remove it from your config.

@lgierth any protocal based udp will be not supported anymore in future?

[Stebalien]

We're actively working on adding support for QUIC: https://github.com/libp2p/go-libp2p-quic-transport

@Stebalien get it, Good job
