TCP Host Access Details

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.
