Example 6.5. H.323 with private IP addresses
In this scenario a H.323 phone is connected to the D-Link Firewall on a network with private IP addresses. To
make it possible to place a call from this phone to another H.323 phone on the Internet, and to allow H.323
phones on the Internet to call this phone, we need to configure rules. The following rules need to be added to the
rule-set, 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 phone 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.
