2 questions I didn't fully understand
$fwcmd add allow all from any to any via lo0
- When I did a verbose I was surprised to see all the
intercomunications. I couldn't find any information to what it is? I have
never seen this rule.
$fwcmd add divert natd all from any to any via $<external interface>
- Divert all packets through natd.
- After some testing it seemed to me that it had to be at the beginning
of my rules. But it says all packets, isn't a ftp a packet, therefore it
would be forwarded. I think I have it down but I just want to be clear.
