i need n open a range of ports for my asterisk work and my no-ip(free dns), but I have the following problem.
If you use the following "ip nat inside source static 10.0.0.2 interface dialer0" asterisk works but my not-ip updated my ip private
If you use the following
"ip nat ins source list 1 int dialer0 "
my no-ip update my ip publi but asterisk not work
