Click OK Example 6.7. Using Private IP Addresses This scenario consists of two H.323 phones, each one connected behind the NetDefend Firewall on a network with private IP addresses. In order to place calls on these phones over the Internet, the following rules need to be added to the rule set in the firewall. Make sure there are no rules disallowing or allowing the same kind of ports/traffic before these rules. As we are using private IPs on the phones, incoming traffic need to be SATed as in the example below. The object ip-phone below should be the internal IP of the H.323 phone behind each firewall.
