Change default LAN interface

[fenichelar]

I currently have 4 interfaces on 3 ports:

WLAN: port 1
HOME: port 2 VLAN
GUEST: port 2 VLAN
LAN: port 3

I don't use LAN, I want to delete it. The prevent lockout rule is assigned to it though. Pfsense also defaults to use the LAN interface for config in a number of other places. If I delete LAN and rename HOME to LAN will this be treated like the current LAN interface is treated? If not, is there a way to change what Pfsense uses as the default internal interface? Thanks.
