I am trying to create my own bootstrap node(https://github.com/BenDerPan/simple-bootstrap-node/blob/master/main.go) and make changes with this example(https://github.com/libp2p/go-libp2p-examples/tree/master/chat-with-rendezvous)
It works fine if I run bootstrap node in local network but if I run bootstrap node in different network I am getting a I/O timeout error
Note :I added libp2p.NATPortMap to the new constructor in both programs
