I. NAT/ALG Mode Normal Nat implements address translation by modifying the UDP or TCP packet header address information. However, for VoIP applications, address information must also be included in the TCP/UDP net load, ALG Mode means that the VoIP Terminal in the private network fills in the private network address in the Net Load. The address information is changed to the external address on the NAT when it passes through the nat. Recognition of voice and video protocols (
