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?
