+          * <code>
+IKE DH Group dh2
+IPSec gateway 192.108.116.206
+IPSec ID vpnrire
+IPSec secret rire
+Xauth username</code>
+          * Then run `sudo vpnc tb` to start the vpn
+        * On macos, Open up your System Preferences and select "Network". Click on the little + button at the bottom of the window to create a new connection.Pick "VPN" for the Interface and set the VPN type to "Cisco IPSec". It doesn't matter what you set as the service name. Click on "create". As Server address, input "192.108.116.206" and in the account name and passwords use your login and password for the school identification. As authentication settings, input the group name "vpnrire" and the shared secret is "rire".
