In my company there is a Cisco 3600 router that has a FastEthernet address of 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 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.
