1. Lab name: NAT configures private network to access public network

2. Experimental purpose: access by routers of different networks

3, Experimental Topology:

4. Configuration steps:

R3:

R3 (config) # INTerface GI0/0

R3 (config-if) # ip address 192.168.10.254 255.255.255.0

R3 (config-if) # no shutdown

R3 (config) # interface gi0/1

R3 (config-if) # ip address 100.1.254 255.255.255.0

R3 (config-if) # no shutdown

R3 (config) # route rip

R3 (config-router) # version 2

R3 (config-router) # no auto-summary

R3 (config-router) # network 192.168.10.0

R3 (config-router) # network 100.1.1.0

R3 (config) # ip route 0.0.0.0 0.0.0.0 100.1.1.254

R3 (config) # ip nat inside source static 192.168.10.1 100.1.1.254

R4:

R4 (config) # interface gi0/1

R4 (config-if) # ip address 100.1.254 255.255.255.0

R4 (config-if) # no shutdown

R4 (config-if) # interface gi0/0

R4 (config-if) # ip address 200.1.1.1 255.255.255.0

R4 (config-if) # no shutdown

R4 (config) # route rip

R4 (config-router) # version 2

R4 (config-router) # no auto-summary

R4 (config-router) # network 100.1.1.0

R4 (config-router) # network 200.1.1.0

R4 (config-router) # passive-interface gi0/1

R4 (config-router) # exit

R5:

R5 (config) # interface gi0/1

R5 (config-if) # ip address 200.1.1.254 255.255.255.0

R5 (config-if) # no shutdown

R5 (config) # route rip

R5 (config-router) # version 2

R5 (config-router) # no auto-summary

R5 (config-router) # network 200.1.1.0

5. Verification and testing:

6. Configuration ideas:

(1) configure PC IP address, private network router gateway, relay IP address, external network gateway address

(2) configure rip in public network

(3) configure the next hop in the private network
