![]() ![]() The CLI to configuration for the above translation is as follows This is the simplest form of NAT, where in each inside address is statically translated to an outside address (and vice versa). Any note or doc on NAT is sure to refer to them Static NAT The address is allocated from a globally routable address or network space. Outside global address-The IP address assigned to a host on the outside network by the host owner.Not necessarily a legitimate address, it is allocated from an address space routable on the inside. Outside local address-The IP address of an outside host as it appears to the inside network.Inside global address-A routable IP address assigned by the NIC or service provider that represents one or more inside local IP addresses to the outside world.Typically, the address is from a private address space. Inside local address-The IP address assigned to a host on the inside network. ![]() This glossary is fundamental to understand and describe NAT In other words, NAT makes non-routable addresses routableįigure 2 Shows the topology referenced in the illustrations that follow. Note: It may help to think of NAT as an aid to route IP packets into and out of networks using private address space. NAT is bidirectional- If A gets translated to B on the inside interface, B arriving at outside interface will get translated to A!.Typically, NAT configurations change only the IP address of inside hosts.appear like) a single public IP address, to access the Internet. Enables multiple hosts in a private subnet to share (i.e.NAT basically replaces the IP address within packets with a different IP address.Furthermore, the scope is limited to components that make up the MS-Voice technology. Rather, this document aims to provide a comprehensive review of NAT as it is used in Cisco’s VoIP networks. ![]() The purpose of this document is not to review NAT. Network Address Translation is a commonly used technique to translate IP addresses on packets that flow between networks using different address spaces. If your network is live, make sure that you understand the potential impact of any command. All of the devices used in this document started with a cleared (default) configuration.
