Ethernet 0 is the External NAT Port, Ethernet 0.1 is the port to the NAT PassThru Range
(which is accessible from the rest of the Internet) and Ethernet 0.2 is the Internal NAT Port.
The IP protocol on the Bridge, Wan 0, and Wan 1 have been disabled in this example.
Note: Again, the NAT software is currently designed and has only been tested with one
External IP Port on a Router. In the latest releases of Compatible Systems device software
(versions 4.3 and later), the display in response to the show ip config will display which IP
interface has the variable NatMap enabled (NatMap = On). This can be seen in the above
display for Ethernet 0.
The configuration set up of each IP Ethernet Port is shown below with the corresponding
keywords from the [NAT Global] section. The "agreement" between the keywords of these
sections is also shown.
EXTERNAL NAT PORT, EXAMPLE 3
The configuration of the External NAT Port and its relation to the [NAT Global] section is
shown first.
