Abstract :
Today Internet is very prosperous. Network firewalls have become basic network security equipments. Not only enterprises will set up firewall system, most of SOHOs and individual users also set up a firewall as a standard device. Because public IP is not sufficient in the IPv4-based environment, so most of networks are using NAT (Network Address Translation) mechanism to translation their private IP. Thus NAT also increases the complexity of VoIP (Voice over IP) through a firewall environment. In order to allow VoIP network environment in normal operation in a firewall environment, IETF and the VoIP industry propose a lot of solution. This article is going to present some common frameworks for analysis VoIP operation and looking forward to provide VoIP normally working in a firewall network environment.
