Both work.
If you have enough IP addresses to dedicate one to your Asterisk server, that removes one node in the path from the world. You will need a firewall on the Asterisk server to protect it from outside meddling. If you can put the Asterisk server on the same network as the SIP devices (using a second NIC) that should help performance.

Is the SIP network on the same network as your internet/data LAN?

I was wondering if anyone can give me any pointers or insights of whether or not to have an asterisk server behind a firewall.

I have always ran Asterisk on a public IP but was wondering if I should move it to a local IP behind a firewall.

I am looking to set up a location with 300 SIP phones.

Normally, I would put the Asterisk server on one public IP and let the SIP phones get DHCP from a router on a different IP and they would register to the Public Asterisk server from that IP address.

Should I move the asterisk server behind the same router?

If so, how should the server be set up and what is the best router/firewall hardware to accomplish this environment?

Thanks,
