Asterisk & IPTABLES

These are the issues:

  - Port forwarding for SIP ports (both TCP & UDP)

  - Port forwarding for RTP ports (UDP)

  - Pass public IP address to asterisk

For other purposes, it seems best to do a whole range port forwarding
on the router.  So what is necessary first is an understanding of how
snat works.
