Description	Changing the messages the FortiGate unit displays to users when accessing blocked web sites, email, FTP sessions or infected email attachments.
Components	All FortiGate units.
Steps or Commands	Error messages that appear in the browser when a user attempts to visit a blocked web site or site filtered by FortiGuard, are HTML messages displayed by the FortiGAte unit. These messages are not hard coded, and you can change them as required. To change a error message Go to Config> Replacement Messages. Select the blue arrow for the message category to expand the list. Select Edit for a message, and modify the contents as required. Select OK when done. Replacement messages can be text or HTML messages. You can add HTML code to HTML messages. Allowed Formats shows you which format to use in the replacement message. There is a maximum of 8192 characters for each replacement message. In addition, replacement messages can include replacement message tags. When users receive the replacement message, the replacement message tag is replaced with content relevant to the message. Replacement message tags lists the replacement message tags that you can add. For details on the message tags, see the FortiGate Administration Guide or the FortiGate Online Help.
