BB005x Installation and Configuration Guide The type of NAT supported by BB005x is often called NAPT (Network Address Port Translation) because it maps public addresses to address/port combinations on the private network. NAT also brings inherent firewall capabilities to the router since it will not allow any inbound packets that were not the result of initial requests from hosts on the private network.
BB005x Installation and Configuration Guide Enabling NAT between interfaces allows configuration of global addresses or configuration of reserved mapping. Configuring NAT Global Addresses Configuring a global address pool enables the user to define a pool of public network addresses that NAT can use when translating requests originating from private addresses behind NAT. To configure global addresses, NAT must be configured first. 1.

BB005x Installation and Configuration Guide translates the IP header but not the payload, IP packets may appear to contain errors and can be discarded at their arrival at destination. Firewall triggers are one possible solution. A trigger allows an application to automatically open or close a secondary port when required and, at the same time, it can search packets for the embedded IP address so NAT can translate that properly. ► To configure a trigger: 1.
