How to create a Tendermint local network with same ip

How to set the config.toml file when establish a local Tendermint network with the same ip address. Do I need to set both 'seeds' and 'persistent_peers' for each node?

(other settings are same with node1)

    }
}

I tried many ways. Sometimes I can get nodes run, but transactions cannot be correctly committed.

These are all my settings for creating two validator nodes locally with the same ip address. I got the errors of "duplicate peer" and "Connect to self".

Do I need to set both 'seeds' and 'persistent_peers' for each node?

no, use persistent_peers

Dialed peer with unknown ID - unable to authenticate

please prepend IP:Port pairs with respective node IDs. https://tendermint.readthedocs.io/projects/tools/en/develop/using-tendermint.html#peers. You can use tendermint show_node_id to get node id. Or better, use tendermint testnet command to create a local testnet.
