You have to be a bit more specific. For example is your Asterisk box
behind a router/nat? Or does your asterisk box have two NICs one for
the public and/or natted IP and one for the LAN? You need to specify
your exact setup.

It's probably not a bug. Maybe you are registering by name and the
name resolves to the public IP, and if you are in a DSL cable
connection you public IP will change and perhaps you don't even have a
public IP. Another possibility is that your ISP does not in fact give
you public IPs (like most in the USA) and you have your LAN in the
same network definition as theirs. I mean there are so many
possibilities but you need to specifiy the exact network setup (IPs,
masks, routing, etc.)
