As supplementary service features of AP160 dial-up gateway, this equipment
supports the Packet Filtering and Firewall function using Access List method.
Firewall function restricts the local network access from outside network using
source and destination IP address access list information at Network Layer(IP
Layer) and Transport Layer(TCP/UDP Layer).
Also, using DHCP(Dynamic Host Configuration Protocol), this equipment can
assign the IP address to network client automatically (DHCP server mode) and
can receive the dynamic IP address of itself from DHCP Server(DHCP client
mode). And AP160 dial-up VoIP gateway solves the IP address shortage
problem due to explosive increment of internet user using NAT(Network Address
Translation) protocol. The local IP address can be hidden from outside world
when NAT protocol is used in AP160 dial-up VoIP gateway. This means that
AP160 dial-up VoIP gateway can be used as a security function terminal
simultaneously.
