CS 320 – Network Addressing and Configuration

 

Assignment:  Using the Diagram provided or displayed on Professor Toffler’s web site (Assignment #2, Notes on TCP/IP Networking), specify the IP Address, Subnet Mask and Default Gateway for each PC and Server indicated in the network diagram. If the router is acting as a DHCP server, indicate a range of IP’s that the router will use for the PC’s in the LAN behind the router. Set up the Forwarding Table for each router, indicating the open ports and which IP address it will be pointing at. Use the materials as a reference for port numbers and other information.
