Don't miss anything!

Build a new network topology as shown. Identify all addressing, netmask, routing tables, hostname, etc, issues. Use static routing.
Configure Host1, Host2, and Host3 to be in the DNS domain “4110.dnal.gatech.edu”. Use Host1 as a primary (master) server, and Host 2 as a slave server. Correctly configure resolv.conf for each host.
Use the programs written in lab 2 to calculate maximum sustained raw throughput, and net “data transfer rate” for the following cases. Tabulate your results and explain what is happening in each case. 1 UDP session across the RS-232 link 2 UDP sessions across the RS-232 link 1 TCP session across the RS-232 link 3 TCP sessions across the RS-232 link 2 UDP sessions and 2 TCP sessions across the RS-232 link
Create a firewall filtering configuration on router 2 to block inbound telnet sessions. Demonstrate that this works correctly (ie, Host2 can telnet to Host3, but Host1 cannot).
