This section provides scenario information that may help you in completing the
NAT Translation Rule windows, and other information that explains why NAT
rules created using the CLI may not be editable in Cisco SDM.
Static Address Translation Scenarios
The following scenarios show you how you can use the static address translation
rules.
Scenario 1
You need to map an IP address for a single host to a public address. The address
of the host is 10.12.12.3. The public address is 172.17.4.8.
The following table shows how the fields in the Add Address Translation Rule
window would be used.
Result
The source address 10.12.12.3 is translated to the address 172.17.4.8 in packets
leaving the router. If this is the only NAT rule for this network, 10.12.12.3 is the
only address on the network that gets translated.
