A network associate is configuring a router for the weaver company to provide internet access. The
ISP has provided the company six public IP addresses of 198.18.184.105 198.18.184.110. The
company has 14 hosts that need to access the internet simultaneously. The hosts in the company
LAN have been assigned private space addresses in the range of 192.168.100.17 – 192.168.100.30.
Answer: See the explanation
Explanation:
The
company has 14
hosts that need to
access the internet
simultaneously but
we just have 6 public IP addresses from 198.18.184.105 to 198.18.184.110/29.
Therefore we have to use NAT overload (or PAT)
Double click on the Weaver router to open it
Router>enable
Router#configure terminal
First you should change the router’s name to Weaver
Router(config)#hostname WeaverCreate a NAT pool of global addresses to be allocated with their netmask.
Weaver(config)#ip nat pool mypool 198.18.184.105 198.18.184.110 netmask
255.255.255.248
Create a standard access control list that permits the addresses that are to be
translated
Weaver(config)#access-list 1 permit 192.168.100.16 0.0.0.15
Establish dynamic source translation, specifying the access list that was defined
in the prior step
Weaver(config)#ip nat inside source list 1 pool mypool overload
This command translates all source addresses that pass access list 1, which
means a source address from 192.168.100.17 to 192.168.100.30, into an
address from the pool named mypool (the pool contains addresses from
198.18.184.105 to 198.18.184.110)
Overload keyword allows to map multiple IP addresses to a single registered IP
address (many-to-one) by using different ports
The question said that appropriate interfaces have been configured for NAT
inside and NAT outside statements.
This is how to configure the NAT inside and NAT outside, just for your
understanding:
Weaver(config)#interface fa0/0
Weaver(config-if)#ip nat inside
Weaver(config-if)#exit
Weaver(config)#interface s0/0
Weaver(config-if)#ip nat outside
Weaver(config-if)#end
Finally, we should save all your work with the following command:
Weaver#copy running-config startup-config
Check your configuration by going to “Host for testing” and type:
C :\>ping 192.0.2.114
The ping should work well and you will be replied from 192.0.2.114
