Problem: How do you configure a Cisco 2509 to
accommodate a dynamic IP from an
ADSL modem?
----------------------------------------------------------
Requirements
I am trying to accomplish the above as a lab exercise.
I have been unsuccessful and would appreciate advice.
I want to:
A.) Have the 2509 obtain and store the changing dynamic
IP from the ADSL modem.
B.) Route between the 2509 and 2620 via a serial link
C.) Have the 2620 setup as NAT router for the local
LAN of 240 users.
----------------------------------------------------------
Goal
Trying to use the above equipment to simulate the process
of a Cisco 675, Cayman 3220 or similar SOHO router.
----------------------------------------------------------
Constraints
Cannot purchase routers listed in above goal.
----------------------------------------------------------
Questions
1.) Can this be done? I am unable to find anything
on CCO that gives a sample config of this type.
Ref:

2.) Can this be done with one router? Appears no
but the dumb question is the one that you
done ask.
3.) Is there a better way to do this?
---------------------------------------------------------
Thank you for your help.
