Hello guys,
I'm new in PF Firewall.
I have a FreeBSD medium instance on AWS EC2.
I have two interfaces (ifconfig):
ena0: flags=8863<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 9001
inet 172.31.74.65 netmask 0xfffff000 broadcast 172.31.79.255
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384
inet 127.0.0.1 netmask 0xff000000
In other words, a loopback address and private IP address. The public IP isn't show.
Who are ext_if and int_if?
int_if is "lo0" and ext_int is "ena0"?
Or int_if is "ena0" and ext_if doesn't exist?
Thanks
