    I have wuite a big issue unable to resolve it.
    I have a SIP PBOX and it works wonderful behind
    any kind of NAT using STUN but it won;t work behind
    my home ADSL cisco NAT.
    I think in some way the Cisco nat implementation break stun
    so I might try to upgrade the IOS.
    But here I wanted to ask what I can do to forward
    external connections from my WAN ADSL interface
    to my internal network so that connection to
    UDP ports 5060 to 5070 are forwarded to my Voip pbox
    which ahs address
    I tryed unsuccesfully with nat outside.
    anyone has some hint for this issue ?
