RIP problem

Hi guys,
I have a network like this.

in R1 default gateway 30.42.0.1 and it has scr nat to 30.42.0.2 it has some dst nat based on my requirement.
in R3 default gateway 40.42.0.1 and it has scr nat to 40.42.0.2 it has some dst nat based on my requirement.
In R2 default gateway 10.42.0.1 it has scr nat to 10.42.0.2.
I wrote a static route in all the routers I need to use RIP.
I make an instance of RIP and add all interfaces to it interface -template for all routers. It didn’t work? Does it have any trick?
please help me?
Thanks so much.

No point even trying to guess what’s wrong without seeing the configuration of each RIP router.

it has some dst nat based on my requirement

Can you elaborate a little bit?
