Network Address Translation (NAT)
NAT is a method of connecting multiple computers to the Internet (or any
other IP network) using one IP address. This lets users cost-effectively and
efficiently connect their networks to the Internet.
Whether on a global or local port, NAT provides translation only upon receipt
of a packet, which NAT will translate, not translate, or filter, depending on
the user-specified parameters (further described below). If the decision is
made to “translate,” the packet will be modified internally, and eventually
sent on to the IP Gateway to be processed. If the decision is made not to
“translate,” the packet will not be modified in any way. If the decision is
made to “filter,” the packet will be discarded without any further action
required.
NOTICE: You must Save and Restart for any changes in NAT configuration
parameters to take effect.
