I have several issues with my PAT config. On the attached image of the topology:
1. Only hosts on network 10.0.1.0 / 25 can ping interface 128.10.10.2 / 24 (PAT is successful for this network)
2. Network 10.0.10.0 / 25 (VLAN) can ping 128.10.10.1 / 24, but cannot ping 128.10.10.2 / 24
3. The rest of the networks, whenever i ping 128.10.10.1 / 24 , it says destination host unreachable.
Here are the configurations i used in this topology.
R1(config)#int fa1/0
R1(config-if)ip nat inside
R1(config)#int s0/0/0
R1(config-if)#ip nat outside
R1(config-if)#exit

I also tried configuring the other interfaces in the router as IP NAT INSIDE but still the same result (this is just me experimenting).
What have I done wrong?
