Setting up dynamic/port Mapping
Step1:
Creating a global IP address pool:
It is possible to set up multiple pools, but the overlapping of the
range of IP addresses for each pool is not allowed.
Command
nat pool
<poolname> <global-startip> <global-endip>
Parameters
<poolname>
name of IP pool
<global-startip>
first global IP address
<global-endip>
last global IP address
Step2:
Mapping between local IP addresses and the global IP address pool
Command
nat
map|portmap <local-startip> <local-endip> <poolname>
Parameters
map
set up a dynamic mapping
portmap
set up a port mapping
<global-startip>
first global IP address
<global-endip>
last global IP address
<poolname>
Name of IP pool to be mapped
Step3:
Activating translation to the specified interface. the interface will be
subject to translation:
Command
nat outside
<ifname>
Parameters <ifname>
Interface
name
Configuration example
(conf)# nat pool test 168.126.188.101 168.126.188.110
creates a global IP address pool called test. The range of
the pool is from 168.126.188.101 to 168.126.188.110.
(conf)# nat pool test2 168.126.188.111 168.126.188.111
creates a global IP address pool called test2. The range of
the pool is from 168.126.188.111 to 168.126.188.111.
(conf)# nat map 192.168.1.1 192.168.1.254 test
establishes dynamic mapping between local network
