Dynamic NAT
The topology diagram is as follows:
Experimental procedure
1. Set up layer 3 switch sw
Sw#conf t Enter configuration commands, one per line. End with CNTL/Z.sw (config) # no ip routing sw (config) #
2. Set up routing R1
R1#conf t Enter configuration commands, one per line. End with CNTL/Z.R1 (config) # int f 0/1R1 (config-if) # ip add 192.168.20.1 255.255.255.0 / / only set the IP address and subnet mask R1 (config-if) # no shut * Mar 1 0000 0/1R1 54.063:% LINK-3-UPDOWN: Interface FastEthernet0/1, changed state to up*Mar 1 0015 063:% LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1 Changed state to upR1 (config-if) # int f 0/0R1 (config-if) # ip add 192.168.100.1 255.255.255.0 / / only set the IP address and subnet mask R1 (config-if) # no shut R1 (config-if) # ex * Mar: 08.423:% LINK-3-UPDOWN: Interface FastEthernet0/0, changed state to up*Mar 100: 01VR 09.423:% LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0 Changed state to upR1 (config) #
3. Set up three PCs
PC1
PC1 > PC1 > ip 192.168.20.20 192.168.20.1Checking for duplicate address...PC1: 192.168.20.20 255.255.255.0 gateway 192.168.20.1PC1 >
PC2
PC2 > PC2 > ip 192.168.20.30 192.168.20.1 Checking for duplicate address...PC1: 192.168.20.30 255.255.255.0 gateway 192.168.20.1PC2 >
PC3
PC3 > PC3 > ip 192.168.100.10 192.168.100.1Checking for duplicate address...PC1: 192.168.100.10 255.255.255.0 gateway 192.168.100.1PC3 > Note: network-wide interconnection can be achieved theoretically, as shown in the following figure. If you cannot connect, please check the command yourself.
In order to meet the requirements of the experiment, we will formally set up the dynamic NAT.
R1
R1 (config) # R1 (config) # ip access-list standard zhy / / set the named access control list R1 (config-std-nacl) # permit 192.168.20.0 0.0.255 R1 (config) # ip nat pool test 12.0.10 12.0.20 netmask 255.255.255.0 / set up the public network address pool R1 (config) # * Mar 1 00:09 : 46.123:% LINEPROTO-5-UPDOWN: Line protocol on Interface NVI0 Changed state to upR1 (config) # ip nat inside source list zhy pool test / / implement network address translation R1 (config) # int f 0/1R1 (config-if) # ip nat inside / / enable internal NATR1 (config-if) # int f 0/0R1 (config-if) # ip nat outside / / enable external NATR1 (config-if) # ex verification result
The above is the address translation of dynamic NAT, which does not need to be specified manually. It automatically translates addresses within the range.
