Will any of these work for you? 1. Simon Horne's softphone with built-in NAT traversal. http://www.pacphone.com/ 2. On the NAT, forward TCP port 1720 to your endpoint. 3. Put another GK on the private LAN. If not, please specify your requirements. Softphones? ATAs? Hardphones? Do you have administrative control of the NAT(s)? How many endpoints behind a given NAT? Approximate size of system? --Stewart ________________________________________ From: JM Hyppolite [mailto:jm.hyppolite@xxxxxxxxxxxx] Sent: Friday, March 31, 2006 7:45 AM To: openh323gk-users@xxxxxxxxxxxxxxxxxxxxx Subject: Gatekeeper interworking with Nated endpoints Hi, It?s possible to make calls from nated endpoints to endpoints with public IP addresses. But how can I get endpoints with public IP addresses to call endpoints behind a NAT box?
