CORRECT TEXT
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.

First you should change the router’s name to TUT
Create a NAT pool of global addresses to be allocated with their subnet mask.
Create a standard access control list that permits the addresses that are to be translated
Establish dynamic source translation, specifying the access list that was defined in the prior step
—–
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 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 TUT
Router(config)#hostname TUT
Create a NAT pool of global addresses to be allocated with their subnet mask.
TUT(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
TUT(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
TUT(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:
TUT(config)#interface fa0/0
TUT(config-if)#ip nat inside
TUT(config-if)#exit
TUT(config)#interface s0/0
TUT(config-if)#ip nat outside
TUT(config-if)#end
Finally, we should save all your work with the following command:
TUT#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
