1. Assign IP addresses and enable the interfaces as follows:
    

   Device	Interface	IP address	Mask
   ISP	S 0/0	100.10.10.2	255.255.0.0
   ISP	FaE 0/0	20.20.20.1	255.255.0.0
   Houston	S 0/1	100.10.10.1	255.255.0.0
   Houston	FaE 0/0	192.168.1.97	255.255.255.224
   Houston	FaE 0/1	192.168.1.33	255.255.255.224

2. Test connectivity between all devices. You should be able to ping from each end node to all other
   end nodes.
    
3. An extended access-list HFW1 has already been created on the Houston router. The goals of the
   access-list are to permit PC 3 to access Server 1 and to block all other hosts from accessing the
   servers on the SW3 LAN. Apply the access-list HFW1 to the Houston interface that will meet these
   requirements.
    
4. Test functionality of this ACL using a Simple PDU from PC 3 to Server 1 and from PC 4 to Server 1.
   The ping from PC 3 should succeed and the ping from PC 4 should fail.
    
5. Test ping from PC 3 and PC 4 to Server 2 and Server 3. These should fail as well.
