set the mask for the speciﬁed destination IP address, place the cursor in the Dest Mask ﬁeld and

type the mask.

Protocol — Use this pull-down list on the Modify Firewall Entry window 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 on the Modify Firewall Entry window 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 7 and Table 8 supply a list of the standardized

TCP and UDP port numbers.
