About Network Address Translation ALG

The Oracle® Enterprise Session Border Controller supports Network Address and Port Translation (NAPT) and Trivial File Transfer Protocol (TFTP) functionality over media interfaces, collectively known as Network Address Translation (NAT) ALG. The NAT ALG feature is implemented as an extension of the static flow feature.

In some applications, the Oracle® Enterprise Session Border Controller acts as an intermediary device, positioned between endpoints located in an access network and application servers located in a backbone network. The Oracle® Enterprise Session Border Controller ’s NAT ALG feature enables these endpoints to use non-VoIP protocols, such as TFTP and HTTP, to access servers in a provider’s backbone network to obtain configuration information.

NAT ALG parameters support RTC and can be dynamically reconfigured. The active NAT ALG configuration can be replicated on the standby SD in an HA configuration.
