I have a problem, this system is so fierce that it does not allow me acces to even my own website...anybody can help? I need access to any site I deem necessary!
Generally speaking, you can access any site on the internet through the web proxy. This depends entirely on the filter configuration being deployed though. My recommendation is to contact the support team that works with your account with a full description of the problem, including screencaptures of any errors, details of how you are deploying the proxy (whether you are using a Direct Proxy, WDS Connector, or McAfee Client Proxy), and as much other information as you can provide.
