NAT static conversion
I. Experimental environment and objectives
A switch, a router and three PCs are interconnected across the network and configured with static NAT translation, as shown in the following figure
II. Operation script
1. In switch SW
SW#conf t
SW (config) # no ip routing
SW (config) # int f1and0
SW (config-if) # speed 100
SW (config-if) # duplex full
two。 In router R1
R1#conf t
R1 (config) # int f0bin0
R1 (config-if) # ip add 192.168.10.1 255.255.255.0
R1 (config-if) # no shutdown
R1 (config-if) # speed 100
R1 (config-if) # duplex full
R1 (config-if) # int f0bin1
R1 (config-if) # ip add 10.0.0.1 255.255.255.0
R1 (config-if) # no shutdown
3. In VPCS
VPCS [1] > ip 192.168.10.2 192.168.10.1
VPCS [1] > 2
VPCS [2] > ip 192.168.10.3 192.168.10.1
VPCS [2] > 3
VPCS [3] > ip 10.0.0.10 10.0.0.1
VPCS [3] > 1
VPCS [1] > ping 10.0.0.10
VPCS [1] > 2
VPCS [2] > ping 10.0.0.10
4. In router R1
R1 (config-if) # exit
R1 (config) # ip nat inside source static 192.168.10.2 10.0.0.3
R1 (config) # ip nat inside source static 192.168.10.3 10.0.0.4
R1 (config) # int f0bin0
R1 (config-if) # ip nat inside
R1 (config-if) # int f0bin1
R1 (config-if) # ip nat outside
R1 (config-if) # end
R1#debug ip nat
5. In VPCS
VPCS [2] > 1
VPCS [1] > ping 10.0.0.10
VPCS [1] > 2
VPCS [2] > ping 10.0.0.10

4. Experimental results
The results show that the static NAT is configured successfully, as shown in the following figure
