5. router (config) # ip access-list extended cisco creates a named access control list named cisco
Vi. Static address translation
1. Configure the IP address of the external Port
Router (config) # interface s0
Router (config-if) # ip address 61.159.62.129 255.255.255.255.248
2. Configure the IP address of the internal port
Router (config) # interface e0
Router (config-if) # ip address 192.168.100.1 255.255.0
3. Static address translation
Router (config) # ip nat inside source static 192.168.100.2 61.159.62.130
4. Enable NAT on internal and external ports
Router (config) # interafce s0
Router (config-if) # ip nat outside
Router (config) # interafce e0
Router (config-if) # ip nat inside
VII. Dynamic NAT configuration
1. Configure the IP address of the external Port
Router (config) # interface s0
Router (config-if) # ip address 61.159.62.129 255.255.255.255.248
2. Configure the IP address of the internal port
Router (config) # interface e0
Router (config-if) # ip address 192.168.100.1 255.255.0
3. Define the internal network to allow access to the external network
Router (config) # access-list 1 permit 192.168.100.0 0.0.255
4. Define a valid IP address pool
Router (config) # ip nat pool chen 61.159.62.129 61.159.62.190 netmask 255.255.255.248
5. Network Address Translation
Router (config) # ip nat inside source list 1 pool chen
6. Enable NAT on internal and external ports
Router (config) # interafce s0
Router (config-if) # ip nat outside
Router (config) # interafce e0
Router (config-if) # ip nat inside
8. PAT Configuration
1. Configure the IP address of the external Port
Router (config) # interface s0
Router (config-if) # ip address 61.159.62.129 255.255.255.255.248
2. Configure the IP address of the internal port
Router (config) # interface e0
Router (config-if) # ip address 192.168.100.1 255.255.0
3. Define the internal network to allow access to the external network
Router (config) # access-list 1 permit 192.168.100.0 0.0.255
4. Define a valid IP address pool
Router (config) # ip nat pool chen 61.159.62.129 61.159.62.190 netmask 255.255.255.248
5. Implement conversion of Reusable IP addresses
Router (config) # ip nat inside source list 1 pool chen overload
6. Enable NAT on internal and external ports
Router (config) # interafce s0
Router (config-if) # ip nat outside
Router (config) # interafce e0
Router (config-if) # ip nat inside
