There are several traffic processes that NIS blocks by default. I have cobbled together a .jpg file of what they look like within my Settings/Firewall/Traffic Rules tab, below. I would like to be able to look up exactly what each one of these traffic processes are and what they entail, so I can understand which processes should continue to be blocked, and which I can let through if I choose.
Anyone who has an idea of this, please let me know. I appreciate your help. Thanks.
