do you have a firewall port pointing back to your asterisk server for your iax2 port? or is blanket set as the dmz? have you ran a traffic dump yet to see if the client is passing packets to the router? (could be router is not allowing iax2 back in)

    Hey Henry, can you pop us an ascii picture of your network and
    example of your profile your using..
    Have you done a query on the inside lan to see if the returned
    address of the fqdn is that of your asterisk server?

        Hi all, I am going on vacation in a couple of weeks and so I
        have set up a
        Zoiper softphone on my Laptop so I can
        make international calls to Canada via my Asterisk box.
        Actually since I downloaded the Zoiper I set up both an IAX
        and SIP
        softphone using two different extensions 203/204
        I noticed that while the SIP phone works with my external
        domain name (on
        the same LAN) my IAX connection will only works if I
        use my local server's IPaddress. i.e. doesn't recognize the
        domain name. I'm
        sure that if I use the IAX connection outside of the LAN
        using the domain name it will work but why doesn't it work
        from the LAN
        side?
