Bind specified IP for port 26656

[DaveWK]

Currently when the node runs, port 26656 is bound to 0.0.0.0:26656 -- in some instances such as with NAT or with multiple NICs, this will over-expose traffic to un-intended IP's.

Example: Public IP: 1.1.1.1 Public NIC: 192.168.1.2 Private NIC: 192.168.5.2

I want to be able to specify 192.168.1.2:26656 as the "listener" address so that there is no traffic sent/received on 192.168.5.2:26656, which would be the case if the app is listening on 0.0.0.0:26656

This functionality exists (thanks Fraccaman!) -- in the config.toml there is a parameter called p2p_address which can be adjusted from 0.0.0.0:26656 to the desired value. I would suggest adding a section to the docs for the config.toml params to avoid confusion

After getting it up and running, I noticed that the listen_address being advertised by tendermint was my private IP. I had to change the tendermint config toml from: external_address = "" to: external_address = "tcp://<Public IP Goes here>:26656"

Sorry, this was assigned to the wrong person, I will update the docs promptly. Sorry for the wait @DaveWK
