Updated on November 24, 2014

Configure a VPN Connection

Complete the following steps to create the VPN connection:

  1. In the System Tray, click the network icon and click Open Network and Sharing Center.
  2. To create the VPN, click Set up a new connection or network.
  3. Select Connect to a workplace and click Next.
  4. Click Use my Internet connection (VPN).
  5. Enter and select settings as necessary, then click Next.
  6. Enter and select settings as necessary, then click Connect.
  7. Click Close.
  8. To edit the VPN connection properties, in the Network and Sharing Center, click Change adapter settings.
  9. Right-click the VPN connection and select Properties.
  10. Select the Security tab.
  11. Select the Type of VPN or Authentication as required.
  12. Click OK

Exploring VLANs

In step 2, you ping each of the other workstations connected to the switch. This test should succeed because all workstations are members of the same VLAN.

In step 9, a ping from Wrk1 to all other workstations fails because the port connecting Wrk1 to the switch is now in a different VLAN. Hosts can only communicate with other hosts that are connected to switch ports that are assigned to the same VLAN.

In step 12, a ping to Wrk3 succeeds because the switch port connecting that device is now associated with VLAN 12. Members of the same VLAN can communicate with each other.

Install Network Security Appliance

To complete this lab:

  • Select the IPS with Application Level Gateway Firewall security appliance.
    • The Intrusion Protection System (IPS) can terminate security breaches. An IDS also monitors, logs, and detects security breaches but takes no action to stop or prevent the attack.
    • The application level gateway firewall is capable of filtering based on information contained within the data portion of a packet.
  • In the Networking Closet:
    • Connect the security appliance to the rack below the UPS.
    • Provide power to the security appliance through an outlet on the UPS's BANK 1 (Critical Load) area.
    • Toggle the security appliance's power switch to power on the device.
  • Confirm that the computer in the Networking Closet (named Server) has a successful connection to the Internet.

Complete the following steps:

  1. To connect the security appliance to the rack, expand the Security Appliances category on the Shelf.
  2. Drag the security appliance to the rack slot below the UPS.
  3. To provide power to the security appliance, change to the back view of the rack.
  4. Expand the Cables category on the Shelf, and select the AC Power cable.
  5. In the Selected Component window, drag the Female connector to the port on the security appliance.
  6. In the Selected Component window, drag the Male connector to an outlet on the UPS's BANK 1 (Critical Load) area.
  7. To turn on the security appliance, toggle the security appliance's power switch.
  8. To connect the local area network to the security appliance, select and drag the Cat5e cable from the Router's FE0/1 port to the X0 (LAN) port on the security appliance.
  9. To connect the existing router (and its connection to the ISP) to the security appliance, select the Cat5e cable on the Shelf.
  10. In the Selected Component window, drag the one connector to the Router's FE0/1 port.
  11. In the Selected Component window, drag the other connector to the X1 (WAN) port on the security appliance.
  12. To confirm that the computer in the Networking Closet (named Server) has a successful connection to the Internet, click on the Windows icon on the monitor.
  13. Click on the network icon in the Task Bar and select Open Network and Sharing Center. The diagram should indicate an active connection to the CorpNet network and the Internet.

  1. To connect the cable modem/router to the rack, expand the Routers category on the Shelf.
  2. Drag the device to a rack slot below the UPS.
  3. To provide power to the device, change to the back view of the rack.
  4. Expand the Cables category on the Shelf, and select the AC Power cable.
  5. In the Selected Component window, drag the Female connector to the port on the device.
  6. In the Selected Component window, drag the Male connector to an outlet on the UPS's BANK 1 (Critical Load) area.
  7. To turn on the cable modem/router, toggle the power switch to the on (I) position.
  8. To connect the cable modem/router to the wall plate and ISP, select the RG-6 coaxial cable on the Shelf.
  9. In the Selected Component window, drag a connector to the coaxial connection on the cable modem/router.
  10. In the Selected Component window, drag the other connector to the coaxial connection on the wall plate.
  11. To connect the cable modem/router to the security appliance, select the Cat5e cable on the Shelf.
  12. In the Selected Component window, drag one connector to the cable modem/router's LAN port.
  13. In the Selected Component window, drag the other connector to the X2 (WAN) port on the security appliance.
  14. To simulate the loss of service from one of the ISPs, remove the DSL phone cable from the wall plate.
  15. To confirm that the computer in the Networking Closet (named Server) still has a connection to the Internet, click the Windows icon on the monitor.
