CS-5200
To set up Near-End NAT Traversal for IP Endpoints on a CS-5200 system:
1. Configure the firewall/NAT device for a static mapping. This associates a public IP
address with the Inter Tel CS-5200/5400/5600 native private address.
2. In the DB Programming IP Connections folder, program the NAT IP Address to be the
public address that was associated with the native private address in step 1.
3. In DB Programming, create an IP endpoint and specify the MAC address.
4. In the IP Settings folder for the newly created IP endpoint from the Internet, set the NAT
Address Type to
NAT, as shown in the example below.
5. Configure the IP endpoint (that is on the Internet) to communicate with the Mitel CS-
5200 (public) NAT address. You can do this through the IP endpoint setup sequence or
through the IP endpoint Web page. The address to use is the public address associated
with Mitel CS-5200 main IP address – regardless of whether the system is a Mitel CS-
5200 or a Mitel CS-5400.
IMPORTANT
Configure the firewall security settings for the newly mapped IP
address(es) as described in “Port Usage and Protocols” on page B-20.
Depending on how the particular firewall defaults its security, failure to
configure the security may result in no-audio conditions or security
vulnerabilities.
