Bootstrapping in the same wifi network?

Hello,

I’m using the jsipfs and I tried to get a test net up, but bootstrapping doesn’t seem to work. I have 2 computer under the same wifi network. exchanged address like:

ipfs.bootstrap.add(/ip4/192.168.1.27/tcp/4002/ipfs/QmW16nMgkcJqeZNnaVa1k9DyYB7J8VwH1gxdYfiP8xp71p)

but the two computer didn’t seem to see each other. I have waited for quite long time, didn’t see the db.events.on(‘replicated’) (orbitdb) event fired.

What should I do?

Also the example https://github.com/orbitdb/orbit-db/blob/master/GUIDE.md#replicating-a-database doesn’t work for me either, because both orbitdb instances will need the port 4002, and I didn’t see an option to change the port?

Thanks.

(sorry, I asked on orbitdb forum first, no response. )
