IMPORTANT: This section replaces the information contained in KB73701 - FAQs for Web Gateway 7.x licensing.

Where can I see how many users are currently connected to MWG? 
There is no counter and no way to determine the number of users who are currently connected to the MWG.
Does MWG deny any new connections if the number of connections is over the maximum allowed by our license?
In MWG 7.x, there is no denial of new connections. Even if you go over your limit, filtering and browsing will continue as normal.

Can I use the same license file on multiple MWG Appliances?
Yes. You can import the same license file to multiple MWG Appliances.

What happens when my license expires?
The answer depends on your license type. There are two different types of licenses:
  • Purchased - After your license expires, you will not be able to download any new updates for the filtering engines, but you will still be able to use the rule engine and filter traffic. MWG will still serve requests.
  • Evaluation - After your license expires, your updates will not download and filtering will not work. You cannot use the engines within MWG and it will not serve requests. 

Where can I download my license file?
To download a license file, log on to https://contentsecurity.mcafee.com/, and click the Licenses tab to see your available licenses. If you do not have a logon account, call or email McAfee Customer Service, and they can create one for you. You can contact Customer Service as follows:

How do I renew my license?
Contact your sales representative. Alternatively, you can call or email Customer Services and they can provide you with the details.

How do I obtain the trial or evaluation license?
You can complete the form at: https://www.mcafee.com/enterprise/en-us/downloads/trials.html for a trial license.
The request is sent to the McAfee licensing team. They will send you a trial license, valid for 30 days.

How do I get access to the content security portal?
Send an email to Licensing@mcafee.com with your valid MWG grant number, first and last name of the contact person, and the official email ID.

What are the MWG default logon credentials?
For the GUI manager:
  • User name: admin
  • Password: webgateway
For Root (SSH): There is no default password. The password must be set during installation.

What SSH commands can I use to obtain the Serial Number and MAC address?
Use the following commands to obtain the Serial Number and MAC address of remote Appliances using SSH:
  • Serial Number:  cat /etc/mwg/serial
  • MAC address: ifconfig -a | grep HWaddr

Can I downgrade MWG to a previous software version?
Downgrade is not supported. But, it is possible to reimage the appliance with your previous version and import a backup.

Can I reimage my MWG 5500 appliance to run Email Gateway?
Appliances cannot be reimaged for any use other than for what they were originally purchased for. Although the hardware is the same for the MWG and Email Gateway Intel®-based 5500 appliances, the BIOS and licensing are different, so this operation is not supported.

Why am I unable to play videos from vimeo.com? I have added the site to the URL whitelist, global whitelist, and certificate whitelist, but am still unable to play videos.
Make sure that you have Streaming Detection enabled before the call to antivirus.

You must have the rule Skip on streaming media that uses the StreamDetector.IsStream property. If not, import a fresh Gateway Antimalware ruleset from the rule library. This ruleset contains the required rule.

Why do some report entries for blocked sites show an average browsing time as longer than a minute when the correct browsing time on a blocked site must be zero?
Browse time is tracked only by user and IP address, and not by site. What you are seeing is a side effect of how data is stored in the database. 

Is it possible to add comments to an external list text file? For example, when setting up an IP list, I want to add comments for my team members to indicate the correct syntax for the list. 
For plain text files, you can use regex statements to identify which lines are imported. For example, if you want to treat any line that starts with the '#' character as a comment, you must use a regex statement such as ^[^#].*, so only strings that do not start with '#' are included in the list.
