Scenarios
The following scenarios and questions are designed to draw together the content of the chapter
and exercise your understanding of the concepts. There is not necessarily a right answer to each
scenario. The thought process and practice in manipulating each of the concepts is the goal of
this section.
Scenario 11-1
Your company, a medium-sized law firm, has been dialing up from individual PCs to receive
information from a data warehouse service.
It has recently been decided to network the PCs, which are running Windows 98 or 95, to gain
access to the data through the Internet. You have contacted a local ISP and will maintain a leased
line to their POP. You have approximately 15 lawyers and 20 support staff members with which
to deal. Internet usage will be tolerated only for the lawyers on staff and certain research assistants.
The ISP has given you a single IP address--187.202.4.6. Based on this information, answer or
complete the following questions and tasks.
1
What router would you select for the office?
2
What would be your IP address scheme?
3
Create the NAT configuration that would be used for this connection.
4
Describe your solution to the Internet access policy that is described for the lawyers and
office staff.
Scenario 11-2
Your company has merged with a smaller entity. You will provide their Internet access over a
newly installed T1 facility. Their IP address scheme uses three private Class C addresses--
192.168.11.0/24, 192.168.22.0/24, and 192.168.33.0/24. You are currently using the 10.0.0.0
network.
The newer, smaller company currently has no Internet access. Your provider has given you a
CIDR block of 103.112.8.24/29. You are currently using 103.112.8.25--103.112.8.29 for
addresses on your DMZ. You have been using 103.112.8.30 for your 10.0.0.0 NAT translation.
Based on this information, answer or complete the following questions and tasks.
1
What can you do to enable translation of the new company's address space?
2
Create the NAT configuration that would be used for this connection.
3
What recommendation would you have for the consolidation of address space?
