NAT

Network Address Translation/Port Address Translation (NAT/PAT) gateway is designed for IP address simplification and conservation, as it enables private IP network that uses no registered IP addresses to connect to the Internet. NAT/PAT operates on a cable modem router, connecting to Internet, and translates the private (not globally unique) addresses in the internal network into legal addresses before packets are forwarded onto the Internet. As part of this functionality, NAT can be configured to advertise only one address for the entire network to the outside world. This provides additional security, effectively hiding the entire internal network from the world behind that address. NAT has the dual functionality of security and address conservation, and is typically implemented in remote access environments.

¾ip nat {enable/disable}

Enable/disable NAT/PAT gateway function

¾nat timer {tcp/udp/gre/icmp/dns} {1~86400 sec} Set aging time for different protocol session

One to one mapping

¾nat static ipmapping add { private ipaddress} { global ipaddress} Set NAT one to one mapping table

Example:

CM>nat static ipmapping add 64.168.39.3 192.168.100.4

Set global IP 64.168.39.3 to private IP 192.168.100.4

CM>show nat config
