For this requirement you dont need to register.

If the host is fixed you don't need to register to make this work. If
you don't want to authenticate invites after a register you need the
insecure option in your peer config.

But the uac module was already suggested to handle authentication
requests and initiate registers.

I dont' understand why. Why not have asterisk register to kamailio? That
way you:
-keep kamailio config simple (enable NAT detection and registrar in the
 default/example config)
-don't have to worry about detecting the chaning ip adress
-don't have to any portforwarding tricks on the asterisk side
