Configuring NAT/PAT Functions

Customer LAN
The SIA2410R is planned to be used as a CPE router for an internet service
over G.SHDSL. The end customer has a LAN structure and uses a private
Class C Network with the IP address range of 192.168.0.0 to 192.168.0.255.
For the Gateway router (SIA2410R) the IP address 192.168.0.100 is used.
The provider of the internet service assigns one public IP address to the end
customer, which is configured at the WAN interface of the Gateway router
(SIA2410R). With the following configuration each PC in the private network
of the end customer (192.168.0.0/24) has access to the internet. This is
achieved by translating/multiplexing the private IP address space to one
single IP address on the WAN interface (10.0.0.150).
To be sure of having the same starting point for configuring the router the
default configuration should be written to the flash memory of the SIA2410R
in advance.
>write config –default
>reboot flash
Afterwards the interfaces can be configured with its IP addresses
>interface lan ip 192.168.0.100 255.255.255.0
>interface wan ip 10.0.0.150 255.255.255.0
and port address translation may be set up by
>nat pool test 10.0.0.150 10.0.0.150
>nat portmap 192.168.0.1 192.168.0.254 test
>nat outside wan
Keeping local traffic local is ensured by disabling bridging on the LAN interface
>interface lan bridge disable
Save configuration
>write config
