Managing Interface ACL Rules
To manage interface ACL rules from the admin section, click on the Network Tab. Click on the node in the map that contains the interface whose ACL rules you wish to modify.
A dialog box that contains the node's informatin will appear. At the bottom of the dialog is a table of all the interfaces contained within the node. Click the "View ACLs" button in the last column of the table to open a dialog that contains the interface's ACL information.
From here you can follow the Using the Frontend-ACL documentation for information on how to add, edit, remove, and reorder ACL rules.
