The inside computer should be able to ping the outside host(PC3)
And the ICMP packet should be visible in the translationa table:
MyR1#<input>show ip nat statistics</input>
Total translations: 0 (0 static, 0 dynamic, 0 extended)
Outside Interfaces: FastEthernet0/0
Inside Interfaces: FastEthernet0/1
Hits: 30 Misses: 37
Expired translations: 8
Dynamic mappings:
-- Inside Source

pool My-Pool: netmask 255.255.255.240
start 193.80.112.40 end 193.80.112.45
