    Hi again.

    Im having a little problem with a VoIP based application.

    Here is the thing.

    I have a zeroshell machine with an ethernet and a wireless card working in AP mode.

    The DHCP of the AP gives addresses, and the ethernet card have the IP.

    Now this is the problem: I have a server that runs an aplication over the 5060 port (voip) . His IP is and is perfectly viewed by all the wireless clients and the LAN users ( and networks) but at the moment of making a call, either client and server cant hear anything from each other.

    This happens only when the server works in a diferent segment that the clients. If i connect the server to the wireless network, along with the clients, the application works perfectly fine.

    I tried with port forwarding and iptables but nothing seem to work.

    Hope you can help.

    Best regards.



    did u allocate some rtp ports i usuall use 10000-21000 udp

    with sip 5060 is good for the call the ring but the actuall call conversation is done through rtp ports


    yeah, but its not an asterisk machine. in fact its not even e Linux machine, its a software used for language laboratories that send the audio via the 5060 port.

    The manufacturer says that the only required port is the 5060.
