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 either permits or denies 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 9 and Table 10 supply a list of the standardized
TCP and UDP port numbers.
