Problem I am having is, ADSL modem/router can forward to pix on a port to port, meaning no range. ADSL is using NAT. Pix 515E is using NAT.
I trying to use a virual IP on the ADSL router will only let me chose IP address that the ADSL router ses incoming. I have SMTP/POP3/SIP working. The problem is RTP, call can establish but only one-way audio. Phone server is Trixbox. I might be trying the wrong kind of NAT statement on the PIX-515E. Thanks
