Issue Description

There are multiple network segments on the AR1200S. How do I configure these network segments to use different fixed public IP addresses to access the Internet?

Handling Process

There are two internal network segments: 192.168.1.0/24 and 172.16.1.0/24, which need to use the fixed public IP address 12.1.1.4 and 12.1.1.11, respectively, to access the Internet.

acl number 3331 (Create an ACL to match the internal network segment 172.16.1.0/24.)

 rule 5 permit ip source 172.16.1.0 0.0.0.255

acl number 3333 (Create an ACL to match the internal network segment 192.168.1.0/24.)

 rule 5 permit ip source 192.168.1.0 0.0.0.255

#

nat address-group 3 12.1.1.4 12.1.1.4

nat address-group 7 12.1.1.11 12.1.1.11

#

interface GigabitEthernet0/0/0

ip address 1.1.1.1 255.255.255.0

#

interface GigabitEthernet0/0/1

ip address 12.1.1.2 255.255.255.0

 nat outbound 3333 address-group 3 (Configure a fixed internal network segment to use a fixed public IP address to access the Internet.)

 nat outbound 3331 address-group 7

 nat outbound 3335 (Configure other internal network segments to use the IP address of the local interface to access the Internet.)
