In my company there is a Cisco 3600 router that has a FastEthernet address of 201.1.110.22/30. My beloved boss gave me the task of changing the CIDR mask from /30 to /29 to create a block of 5 Public IP's. Me, who have no routing experience.


The other part of the task is to:

1 - Assign xxx.x.xx.50 as the Public IP to which all internal IP addresses will be NATed to


2 - Assign xxx.x.xxx.51 as the Public IP for remote management access.


Now, from picking up the CCNA books and notes and watever help i can get i can telnet into the router...get into the interface that has the /30 mask.


It is here that i am stuck and ask for assistance.please.

for the mask change just change it from 201.1.110.22 255.255.255.252 to a mask of 255.255.255.248 . This should be done to whatever is attached to the other of that link also .
