Bootstrap libp2p DHT using my own node: failed to find any peer in table

Hi guys,

I am trying to deploy a private DHT using libp2p independently from ipfs. Souce code of the node is available at https://github.com/lrahmani/snipet-routed-host-bootstrap. I wrote it by piecing together different snippets from libp2p official examples (mostly routed echo).

The issue I am facing is that I cannot find peers using the dht other than the one I bootstraped from. This doesn't happen when I use ipfs public DHT.

Setup when bootstrapping using ipfs public DHT node

• first, get the code

  git clone https://github.com/lrahmani/snipet-routed-host-bootstrap.git && cd snipet-routed-host-bootstrap
  

• then, build it

  go build
  

• run the node with an ipfs public node as bootstrap

  ./node -l 9000 -b /ip4/104.131.131.82/tcp/4001/ipfs/QmaCpDMGvV2BGHeYERUEnRQAwe3N8SzbUtfsmvsqQLuvuJ
