Protocol — Use this pull-down list to select the upper layer protocol that you want to apply to the access control filter. Each access control filter can apply to traffic for all protocols included in the TCP/IP suite, or just to traffic for a single protocol.

Permission — Use this pull-down list to set the permissions for the specified control filter. Options for this field include permit, deny, permit bi-directional, or deny bi-directional. Choosing permit allows the specified packets to be forwarded, while choosing deny blocks the specified packets. Choosing permit bi-directional or deny bi-directional will either permit or deny traffic to and from a specified source or destination.

Port — Enter the port number in this field to create an access control filter that applies only to traffic for a specific TCP or UDP service. Table 19 and Table 20 supply a list of the standardized TCP and UDP port numbers.
