ok so for #1:
When I am installing I have 2 nics.
Now being that em0 will be my link to the cable modem and em1 will be my internal lan, wouldn't it make sense to have the friendly name be on the internal lan (em1) so they would be looking to that hostname?
This is the "symbolic" hostname for the interface not the system hostname. Which one should i pick to apply the symbolic. it allows me to choose em0 or em1.
Should i pick the egress or should i pick the lan facing nic? the egress will of course be the default route since it is forward facing the internet
