Here is my pfsense IPv4 outing table (netatst -r):
Destination Gateway Flags Netif Expire
default 192.168.4.1 UGS em0
127.0.0.1 link#4 UH lo0
192.168.1.0/24 link#2 U em1
192.168.1.1 link#2 UHS lo0
192.168.4.0/22 link#1 U em0
192.168.4.1 08:00:27:fa:40:cf UHS em0
192.168.4.48 link#1 UHS lo0
How do I interpret the link#X vs the interface? The IP of pfsense is 192.168.1.1 (LAN) and 192.168.4.48 (WAN). Is the link a “lower level” concept than the interface? Why can the same link have different interfaces depending on the destination?
