5.router (config) #ip Access-list extended Cisco to create 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 61.159.62.129 255.255.255.248

2. Configure the IP address of the internal port

Router (config) #interface E0

Router (config-if) #ip address 192.168.100.1 255.255.255.0

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 61.159.62.129 255.255.255.248

2. Configure the IP address of the internal port

Router (config) #interface E0

Router (config-if) #ip address 192.168.100.1 255.255.255.0

3. Define internal network allow access to external network

Router (config) #access-list 1 Permit 192.168.100.0 0.0.0.255

4. Define a legitimate IP address pool

Router (config) #ip Nat pool Chen 61.159.62.129 61.159.62.190 netmask 255.255.255.248

5. Implement 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

VIII. Configuration of Pat

1. Configure the IP address of the external port

Router (config) #interface S0

Router (config-if) #ip address 61.159.62.129 255.255.255.248

2. Configure the IP address of the internal port

Router (config) #interface E0

Router (config-if) #ip address 192.168.100.1 255.255.255.0

3. Define internal network allow access to external network

Router (config) #access-list 1 Permit 192.168.100.0 0.0.0.255

4. Define a legitimate IP address pool

Router (config) #ip Nat pool Chen 61.159.62.129 61.159.62.190 netmask 255.255.255.248

5. Implement multiplexing IP address translation

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
