    I have a Quintum A400 sitting behind a LINUX (Firewall/NAT) on a 10.200.x.x ip address.

    I can direct connect to a A200 with and external IP address, after the call is setup the A200 is replying to the Internal IP address of the A400 and not the address of the LINUX (FIREWALL/NAT).

    From reading Quintum Documentation, the A400 is take care of the addressing in the H323 frames, and the NAT would cover the IP address header.

    I was wondering if anyone has seen this before and would you know of any possible fixes for it.



    Its expected…since 323 imbeds the media in the H245 or H225 fast start mechanisms which are in the body of the message. You will need a firewall that has h323 support that will swap inside and outside addresses. Only fix i know is to get a firewall that does support it.


    do you know of any firewalls that do do this, and can this be done
    via linux.
