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.

NAT Details Screen

The NAT Details screen (Figure 4.54) lets the user configure the NAT global

parameters described below.
