Network Address Translation
eNAT is an implementation of rfc1631 and its enhancements. It is specially designed and optimized for embedded gateway devices running real-time operating systems. Multiple hosts in the private TCP/IP network may access the Internet simultaneously using eNAT. It has the ability to restrict Internet access to select hosts in the private network providing better control and define access policies. It supports all TCP and UDP based protocols, which require a single logical connection for their operations like Telnet, SMTP (e-mail), HTTP etc. More complex protocols like FTP, IRC, Real Audio/Video are supported using Application Level Gateways (ALGs). eNAT operates on a router, usually connecting two networks together, and translates the private (globally non-unique) addresses in the internal network into legal addresses before packets are forwarded to another network. As part of this functionality, eNAT has the flexibility to configure and broadcast a single address for the entire network.
