Dynamic translation refers to the conversion of private IP addresses of internal networks to public IP addresses, IP address pairs are uncertain, but random, and all private IP addresses authorized to access the Internet can be randomly converted to any specified legal IP address. That is, dynamic translation is possible by specifying which internal addresses can be translated and which legal addresses are used as external addresses. Dynamic translation can use multiple legal external address sets.

The topology graph will be experimented with below

experimental goal

Address converted to segment 12.0.0.0 when PC1 PC2 accesses PC3

1: Set IP and Gateway for PC1, PC2 and PC3

2: Turn off router function of switch SW

Do duplex matching for interface f1/0

3: Configure router R1

Configure interface f0/1 duplex match Set IP and turn on

Configure interface f0/0 Set IP and turn on

Define access control lists to allow IP access to 192.168.10.0 segments

Define a pool of legitimate IP addresses 12.0.0.10-12.0.0.20

Translate local addresses in ACL1 to global addresses in the zkc address pool

Turn NAT on on port

end Exit to privileged mode Enable NAT detection debug ip nat

4: Using PC1 PC2 ping PC3

R1 is set to detect NAT and you can see details of address translation
