Step1: The first step is to define the addresses that will need to be NAT’d. This is done using a standard access-list:
Example: access-list 199 permit ip any any
Step2:Now that you have defined the addresses that are allowed to use the NAT address, you will enable the actual NAT:
Example: ip nat inside source list 199 interface fa0/4 overload
ip route 0.0.0.0 0.0.0.0 xx
is there something in particular you want to know?
Static routes, in your case the default route, can be configured to point to a numerical next hop (IP address), an exit-interface, or -like your example shows- both:
The ip route 0.0.0.0 0.0.0.0 xx is a command that is statically assigned. This is called a default network because the all-zeros syntax means to catch all routes. The ip route command is not automatically carried in routing updates like the ip default-network command is in some routing protocols. You must redistribute the static command into a routing protocol for it to be carried.
Your default route points to 188.8.131.52 and other default route points to fa0/4 interface.

this commands : To enable Cisco Discovery Protocol (CDP) on an interface, use the cdp enable interface configuration command. To disable CDP on an interface, use the no form of this command.

The need was to reach an host inside a LAN through a VPN connection managed by the LAN gateway (Cisco 1921).
The LAN gateway performs NAT and there was a dedicate nat rule for the host i wanted to reach through VPN.
