Is it true that this port need? and log file

If you are behind a NAT, you should enable TCP port forwarding on your router. Forward port 9998 to the host running P2Pool.

Is it true that this port need forward port 9998? or need port - 8999?

If node raised within the local network for example: IP of 192.168.1.2 and external router IP example: 195.1.1.1 and port forwarding from the external IP 195.1.1.1 on the local node and has a connection with a local network (192.168.1.* addresses ASIC) and external (ASIC IP no local net) in the logs (data/dash/log) is an error a new job is not correctly displayed the address of the working (New work for worker )

The question is how to make the work and visibility in the log file and local and external workers work correctly, when there is a connection both on the local network (the internal farm) and the external worker. If to specify --external-ip external ip that in a log - one worker internal or external (New work for worker.....)
How to configure correctly in this task? and see the full correct log?
Thanks, have a good day.
