Pat is not working on my asa

Question

Hi there. 
I just trying to do PAT with gns3. but not working and i don't have any idea.
(Cisco Adaptive Security Appliance Software Version 8.4(2))
and also i figure out that there are some changes in nat configuration. i did but didn't work. 
I cannot ping from my host 192.168.100.116 to 1.1.12.1 ~ 1.1.12.2, 8.8.8.8 
i turn debug in R1 and i can see the icmp. 
R1#
*Mar  1 01:31:28.091: ICMP: echo reply sent, src 1.1.12.1, dst 10.10.10.1
R1#
*Mar  1 01:31:32.739: ICMP: echo reply sent, src 1.1.12.1, dst 10.10.10.1
R1#
And also can see xlate on ASA
ASA-1# sh xlate
1 in use, 9 most used
Flags: D - DNS, i - dynamic, r - portmap, s - static, I - identity, T - twice
ICMP PAT from inside:192.168.100.116/1 to outside:10.10.10.1/6370 flags ri idle 0:00:04 timeout 0:00:30

This is my topology.

just reload... .. i'm still stuck in the ping. 
changed topology more simple. but still not working. 
Here is all what i did. 
[ASA]
access-list ICMP extended permit icmp any any echo-reply
access-list ICMP extended permit icmp any any time-exceeded
access-group ICMP in interface outside
interface GigabitEthernet0
 description To_UP
 nameif outside
 security-level 0
 ip address 10.10.10.2 255.255.255.0

 nameif inside
 security-level 100
 ip address 10.10.20.1 255.255.255.0

ip route 10.10.20.0 255.255.255.0 10.10.10.2 (I don't think i need this)

 ip address 10.10.20.2 255.255.255.0
ip route 10.10.10.0 255.255.255.0 10.10.20.1 (same as well)
