NAT enables Intranet access to the Internet

 

1. Use static nat

Let r3 ping r2.

 

First, set it on r3 to simulate r3 as a PC.

 

 

 

Ip route 0.0.0.0 0.0.0.0 192.168.13.1

Then, Set

 

 

 

Int e0/1

Ip nat inside

Exit

 

Int e0/0

Ip nat outside

Exit

 

Ip nat inside source static 192.168.13.3 202.66.84.2

2. Use Dynamic NAT

 

Steps:

 

A. Create an external address pool

 

B. Create an internal access list

 

C. Conversion

 

First, simulate R3 and R4 to become a pc.

 

R3

 

!

Ip route 0.0.0.0 0.0.0.0 192.168.13.1

!

 

 

R4

 

!

Ip route 0.0.0.0 0.0.0.0 192.168.14.1

!

 

 

Then on R1

 

 

 

Ip nat pool SHANGWANG 202.66.84.3 202.66.84.10 netmask 255.255.255.0

 

Ip access-list standard BenDi

Permit 192.168.0.0 0.0.255.255

 

!

Ip nat outside

Ip nat inside source list BenDi pool SHANGWANG
