Understanding the CBC VPN

The VPN (Virtual Private Network) allows users to remotely connect to the CBC Network Subnets and behave as if they are physically connected to our local network.

The campus divides neworks into "subnets" and these are then assigned to builings. The subnets within CBC all have open port communication to each other and allow users to freely access local resources. This is why people physically connected on site can access our shares and server applications without any additional security.

Network traffic is securied by a MPLS (Multi-Protocol Label Switching) Firewall. Instead of each building having it's own firewall, all of the buildings are bundled behind one firewall. This allows us to communiate internally without having to "punch holes" in firewalls between the subnets.

When a user connects to the VPN they effectively bypass that firewall and connect directly to a subnet that is located within our MPLS Firewall. This allows them to freely communicate with departmental resources again.
 
 
 
There are a couple things to note when using the CBC VPN. Your local IP address will change and you are for all intent and purpsoes connected to the University of Arizona network at that point. Any online activity done while connected to the VPN will show as if it initiated from campus network. An example would be if someone was torrenting or illegally downloading copyrighted material while connected to the VPN, it would log as a campus entity violating copyright laws.

 

Connecting to the CBC VPN

 

To install the Cisco VPN Client you can visit vpn.arizona.edu in any web browser. You will be greated with a NetID+ login. Log in via whatever NetID+ method you have set up and it will start the Java automatic installer.
Click Continue past the alert.

When the Java automatic installer will start and fail. It always fails. I am not sure why UITS even set it up. After it fails click on the link AnyConnect VPN and it will start the process of downloading the client to your local machine. Launch the downloaded installer and click through the install menu.

  1. Next
  2. I accept the terms and agreements
  3. Install
  4. Finish
Now that the VPN Client is installed on your machine you must connect. Before you can connect to the CBC VPN you must successfully connect to the default UA SSL VPN at least one. It should be listed in the VPN chioce by default. Again connect with the NetID+ method you have set up.
Once connected you will see the lock icon with a green check. This lets you know that you have successfully connected to the UA SSL VPN. Your system will now be able to connect to department specific VPN's. Disconnect the VPN and return to the connection screen.
You must manually enter the VPN location of the CBC VPN in the connection text area. The listing is vpn.arizona.edu/chemistry. Once you have that manually entered, click connect and go through the collection process.
After you have successfully connected to the CBC VPN it will cashe it's local identification and you will now see it appear as Chemistry SSL VPN. It should be the default chioce when laucnhing the Cicso VPN client. 

Please contact CBC IT if you have any problems.
