Last time our experiment was to add a router on the outside.

And this time we add routers to the intranet to do NAT forwarding.

The specific configuration is as follows:

Set the IP according to the above topology map

The Router6 f0/0 interface IP is 192.168.1.254

The following is the configuration information for ROUTER6

router>en

router#config

Configuring from terminal, memory, or network [terminal]?

Enter configuration commands, one per line. End with cntl/z.

Router (config) # inF0/1

Router (config-if) #no sh

Router (config-if) #

%link-5-changed:interface FASTETHERNET0/1, CHANGED state-to-up

%lineproto-5-updown:line protocol on Interface FASTETHERNET0/1, changed

Router (config-if) #Exit

Router (config) # inf0/0

Router (config-if) #no sh

Router (config-if) #

%link-5-changed:interface fastethernet0/0, CHANGED state-to-up

Router (config-if) #IP add 44.44.44.1 255.255.255.0

Router (config-if) #Exit

Router (config) # inF0/1

Router (config-if) #IP add 192.168.1.254 255.255.255.0

Router (config) #IP route 0.0.0.0 0.0.0.0 f0/0

Router (config) #end

Here is the information for the ROUTER7 configuration
