Run a "debug ip nat" on R8 and try pinging R1 from Cat2 again (here is what
mine looks like which is working)
R8#deb ip nat
IP NAT debugging is on

Workbook 1 - LAB 17 Task 17.2
Ping to 200.0.0.1 on CAT2 is not working. NAT is working on R8 for some reason,
anyone can tell why
Enabling NAT on R8 :
interface FastEthernet0/0
ip address 100.100.200.8 255.255.255.0
ip nat enable
duplex auto
speed auto
end
!
interface Serial0/0/0
bandwidth 128
ip address 150.100.78.8 255.255.255.0
ip nat enable
no fair-queue
end
ip nat pool AMER 150.100.78.10 150.100.78.254 prefix-length 24
ip nat inside source list 10 pool AMER
R8(config)#do show ip route | i 200.0.0.1
O 200.0.0.1 [110/1565] via 150.100.78.7, 00:28:30, Serial0/0/0
FOR NAT VARIFICATION :
