Hi,
On my home computer i am running full node, farmer, harvester and wallet trough the Chia GUI.
In my home router i have forward ports 8444 to 8448 to this computer.
I have not disabled upnp in the config file.
Q1: When i have only one computer running chia at home, do i need to disable upnp in the config file here?
In som other location (different ISP line and different router) i have mulitple harvester running where i have setup my full node IP in the config file in harvester → host field. I have also preformed the \ca setup according to the wiki. On these machines i have installed the Chia GUI, but i only run chia start harvester on them.
Now this network have one main router which forward all traffic from ports 8444 to 8448 to a second router where all these harvester are connected to.
Q2: Do i need to configure anything in the second router for all the harvesters to work properly?
Q3: Do i need to disable upnp in the config file for each of these harvesters?
Q4: In the logs of my only harvester machines i see lines like this and would like to fully understand what they mean?

Q5: Based on these logs, is my setup working and farming correctly?
Sure would appreciate som input here 
Note: In the future i do plan to move my full node and all harvester to the same location and on the same network. But currently that is not an option.
