5.6NAT Config
Network Address Translation allows an IP-based network to manage its public (Internet) addresses separately from its private (intranet) addresses. With NAT, each private IP address can be translated to a different public address, or multiple private addresses can be aliases to a single public one. To accomplish this, NAT software snoops both incoming and outgoing packets on the network. It modifies the source or destination address in the IP header to reflect the mapping between internal and external addressing for that network.
NAT functionality appears on Compex SGX3226 with low-level access to packets at the network boundary. Several variations on NAT have also been implemented to provide additional support for application-level protocols.
