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. When
certain types of access or protocols need to be allowed to pass through a NAT
interface, certain techniques and features such as port triggers, ALGs or UPnP
are often used to allow this access. In the BB005x, NAT is always associated
with a pair of security interfaces.
Configuring NAT: ►
Enable security and add the two different security interfaces between which you
wish to enable NAT (see previous section)
When you have created more than one security interface, the NAT column
informs you that you can enable NAT between the two interfaces. For example,
if you create an external interface and internal interface, the table will look as
follows:
The NAT column informs you that you can enable NAT to the internal
interfaces.
To enable NAT between the external interface and the internal interface, click
on Enable NAT to enable NAT to the internal interfaces. The Security page is
refreshed and NAT is enabled.
To disable NAT: ►
Click on Disable NAT to internal interfaces.
