I have the next configuration in router R1
Router R1:
----------
inte fas0/1
ip address 172.20.10.202 255.255.255.248
int fas 0/0
ip address 172.17.240.1 255.255.255.0
ip route 0.0.0.0 0.0.0.0 fas0/1
----------------------------------
Router r1 connect with other router r2, i don't have the configuration of router r2.
I can do ping to r2 172.20.10.201 in router r2, since router r1, but pc in net 172.17.240.0/24 can't do ping to r2 172.20.10.201
The connection is:
pc-----fe0/0-r1-fe0/1------r2
I need to do any configuration additional in r1

No, you don't need any additional configuration on Router 1.
Router 1 has a default route towards R2. All packets from Router 1 will go to R2.
The problem is R2 does not have any routing information back to R1.
ip route 172.17.240.0 255.255.255.0 172.20.10.202 on R2 will fix the problem.

"I need to do any configuration additional in r1"
No, you need a route added to R2 for 172.17.240.0/24 pointing back to R1.
Or you could use NAT if you can't access R2 ie. On R1
int fa0/0
ip nat inside
int fa0/1
ip nat outside
access-list 101 permit ip 172.17.240.0 0.0.0.255 host 172.20.10.202
ip nat inside source list 101 interface fa0/1 overload
