The institution of slavery persisted for a long time in a number of colonies and dependencies. It was particularly widespread in Portugalâs African colonies as part of the plantation economy and as a household institution.
Network Address Translation (NAT) is an IETF standard that enables a local area network (LAN) to use one set of IP addresses for internal traffic and a second set of addresses for external traffic. All necessary IP address translations occur where the LAN interfaces with the broader Internet. NAT converts the packet headers (and in some cases the port numbers in the headers) for incoming and outgoing traffic and keeps track of each session.
The NAT Virtual Interface (NVI) feature removes the requirement to configure an interface as either NAT inside or NAT outside. An interface can be configured to use or not use NAT. The NVI feature allows NAT traffic flows on the virtual interface, eliminating the need to specify inside and outside domains. When a domain is specified, the translation rules are applied either before or after the route decisions depending on the traffic flow from inside to outside or outside to inside.
