[asterisk-users] Asterisk Behind Firewall

I have a /29 to use for the network.
My immediate go-to set-up will be to put the asterisk server on a public IP
off the /29 and harden the IPtables along with other monitoring scripts and
lock down methods. Then add the router on a different /29 IP and have all
the phones register through the router to the public asterisk server and
limit only registrations from that router's IP address.
I then would add the three trunks I need such as inbound/outbound,
international, and 911 to the asterisk box
However, I do think this is best practices. It is my understanding to move
the asterisk box behind a router/firewall and have the phones on the same
subnet of the asterisk box. Then the router/firewall will do the trunking
to the vendors.
I dont know which is best nor do I know the hardware for the
