Product Information The Internet transport protocol, IPv4, does not provide enough unique addresses for all the new hosts on the Internet. A solution to this problem is to convert private internal addresses to an official IP address before the IP packets cross the border to the Internet. This translation is possible since the number of hosts that communicate over the Internet at a given time is considerably lower than the total number of hosts "potentially" connected. Using NAT saves a lot of address space, since the NAT router dynamically assigns the official address to the currently communicating host. Among the various ways to use a NAT router (static NAT, dynamic NAT, etc.), NexGenNAT provides what is often referred to as "IP masquerading" and also known as Network Address Port Translation (NAPT), together with basic NAT. NAPT enables "n to 1"-NAT translations, meaning that a single IP address, valid on the Internet, can be used by several hosts on some private network behind NAT. Basic NAT, on the other hand, can be used if a pool of valid external IP addresses is available (i.e. more than one), enabling "n to m"-NAT translations. Please check the supported architectures. More features can be viewed following this link. Some technical papers can be downloaded here. Documentation Programming and porting manuals are included and an implementation guide is available on request. A test suite to stress your port is supplied.
