In your SIP configs specify that the extensions are natted:
nat=yes
externhost=<External IP address>
localnet=<Local IP subnet>/<local subnet mask>
These are global settings.
It might also be helpful to set canreinvite=no for each extension.
There are probably firewall tricks you can do as well, but its early and
I'm a couple cups of coffee shy.

Thanks for the answer, will try that, but keep in mind that my server
don't have an static public address, i use a dynamic DNS to resolve my
sip domain.
Thanks a lot
