Dynamic NAT

In this setup we need some more public ip addresses so we are going to change the /30 network on the outside to a /28. This will allow us to have 12 translatable addresses.

1. Delete all NAT configuration
2. Change the outside subnet from /30 to /28
3. Configure NAT
   1. Configure inside interface
   2. Configure outside interface
   3. Configure ACL (ip access-list 1 permit 10.0.0.0 0.0.255.255)
   4. Configure a NAT pool(Including the addresses 193.80.112.40 - 45)
   5. Configure dynamic NAT

Configuration examples can be found here.

Static NAT

In this setup we will add a static NAT to the previous configuration

1. Configure static NAT statement, translating the public address of 193.80.112.35 to 10.0.100.100
