Cisco 1600 routing problem

[Mohamadi ZONGO <mzongo at zcp.bf>]

Hi,

I am seting up a router (ROUTER1, see picture below) to go to the internet 
via ROUTER2
For security raison, i change public adresses to private one.
All thing seem  ok if i am connected on  ROUTER1.
I can do a ping on 192.168.0.2 , and idem for  ping www.yahoo.fr
The problem is when i want to do a ping from a computer on LAN1, taking 
ROUTER1 as gateway .
# ping 172.16.0.254  OK
# ping   192.168.0.2  OK
# ping 192.168.0.1 is not OK (entry point of the second router)
# traceroute 192.168.0.1
traceroute to 192.168.0.1 (192.168.0.1 ), 30 hops max, 38 byte packets
  1  fw  (|172.16.0.254)  4.098 ms *  2.046 ms
  2 *
  3 * etc ....

I gather a lot of docs on the net, and all thing seem Ok to me, but i am
sure i am doing something wrong.
Please help.
