    Hi there

    I have an elastix box behind a router (first NAT) and behind a dsl modem (second NAT) then goes to the internet.

    When I want to do a remote registration of extensions, the sip extension can register but there is no audio. The dsl modem is generating a private IP address to the router, and I configured everything as always. The public IP address is being NATTED to the router, I opened (forward) all the ports in the DSL modem to the public IP address, but how do I forward all the ports in the router to the private IP address that generates the DSL modem? There is an IP passthrough function in the DSL modem, that when I activate it, it blocks me everything.

    Maybe all of this is confusing, but if anybody gives me highlights, I can solve this issue.

    Waiting for your comments

    I have always had to have Verizon walk me through bridging their device and allow the static passthru.
