Firewall Issues

The problem:
Some military installations and corporate networks have tight network restrictions which do not allow access to proxy servers, such as the one UMUC employs to give remote users access to library resources.


Is my access restricted by a firewall - how can I tell?

Please try the following:

  1. First, check your browser.
    Run the Browser Quick Check and verify that your browser has cookies, Javascript and SSL enabled.
  2. Then try our proxy server.
    1. Click this TEST LOGIN link. (Enter your MyUMUC credentials, if prompted.)
    2. Do you then get taken to a page which says "Congratulations"? If so, then your access is OK.
    3. If you get a blank page and do not see the Congratulations message, there may be a firewall blocking your access.
  3. Try another browser on your computer.
    For example, if you are using Internet Explorer, try Firefox or Chrome. Does the same thing happen?
  4. If possible, try another computer on the same network.
    Does that computer also have the same issue?
  5. Still unable to get in?
    If you cannot log into our proxy server, you may have restricted access.


Yes, my access appears to be restricted. What are my other options?

  1. Do you have access to a computer or a network someplace else?
    Can you get in from home or from off-base?
  2. Do you have wireless access?
    If you have a wireless device, can you access UMUC Library databases from it? You might try a hotspot connection (if available) or connect through your wireless carrier.
  3. If at a military installation:
    • Are there any less restricted areas around?
      Depending on the location, some areas of the base – library or recreation areas - may not be as tightly locked down.
    • Does the installation have a library?
      If so, check with the base librarian to see what kinds of resources s/he may know about.
  4. Contact the IT staff and ask them to allow firewall access to UMUC's EZproxy server.
    • Ask if they can add a rule to the firewall allowing access to ezproxy.umuc.edu (54.84.104.155) on ports 80 and 443. They may consider it.
    • If you are at a military installation, you can also contact a UMUC representative at your location and ask them for assistance with this. See Asia Locations and Europe Locations for contact information.
  5. Try free search services.
    Sometimes services, such as the following, will link to free versions of articles.
  6. Found an article you need, but cannot access it?
    Let us know what article you need and that you are at a location with restricted access. We will try to find a copy and e-mail it to you.
