DHT discovery is only finding bootstrap nodes NOT other nodes

[elielnfinic]

Hello everyone,

I am currently testing the DHT discovery example file. I created a simple bootstrap node.
When launching 4 instances of 1-dht.js file, they are able to make connection to the bootstrap node only, they can't connect to other nodes.

Do you think this behavior is okay?

Here is my bootstrap node code :

import { createLibp2p } from 'libp2p'
import { tcp } from '@libp2p/tcp'
import { noise } from '@chainsafe/libp2p-noise'
import { kadDHT } from '@libp2p/kad-dht'
import { identify } from '@libp2p/identify'
import { yamux } from '@chainsafe/libp2p-yamux'

const node = await createLibp2p({
    addresses: {
        listen: [
            '/ip4/0.0.0.0/tcp/2000',
            '/ip4/0.0.0.0/tcp/2001/ws'
        ]
    },
    transports: [
        tcp()
    ],
    streamMuxers: [
        yamux()
    ],
    connectionEncrypters: [
        noise()
    ],
    services: {
        identify: identify(),
        dht: kadDHT({
            kBucketSize: 20,
            clientMode: false           // Whether to run the WAN DHT in client or server mode (default: client mode)
        })
    }
})

node.start();


console.log('PeerID: ', node.peerId.toString())
  console.log('Multiaddrs: ', node.getMultiaddrs())

Thank you.
