How to do this:
1) Log into the web management tool via port 5000 or 5001.
2) Go to Control Panel -> "Security" -> Select the "Firewall" Tab
3) Click Create. The "Create Firewall Rules" window will come up
4) Ports -> All
5) Source IP -> Subnet
6) IP Address: 18.0.0.0
7) Subnet Mask: 255.0.0.0
8) Action -> Allow
9) Click OK
10) Click on the "Save" button right under the tabs. If you forget to save like I often do, and try to leave the page, it will ask if you want to leave without saving. Click on no and make sure you save the setting.
You To confirm that the setting is saved, you should see a line with the new firewall setting allowing in all traffic from the MIT 18.0.0.0 IPv4 range and the save button should be no longer click-able.
Now that we’ve allowed anyone from MIT to access the server it is time to deny access to everyone else.
