Chat example

[yale8848]

I see chat example have 2 limit:

1.Both have private IP address (same network).
2.At least one of them has a public IP address.

Can you give some example with how 2 client chat both have private IP address (different network,has no public IP).
thanks very much.

You'd have to enable NAT port mapping and discovery. Take a look at how the libp2p Host is constructed in #278.

As Stebalien said NAT port mapping and discovery would be required for different networks. I am trying to include it in the chat example. Will update you if it works.

@upperwal ok, thanks very much

Please update the example, or add a new one 🙏 I don't understand what you mean in these comments. A complete functioning chat-example would help a lot with understanding how to connect peers behind NAT.

@Arxcis thanks, i will try the example.

As of v0.16.0, libp2p support hole punching, which should help with connectivity for nodes behind a NAT.
