TCP to use the TCP port number contained in an incoming packet as the forwardin
criterion. Selecting TCP requires that you specify a source port mask and/or a destination
port mask. The user may also identify which flag bits to filter. Flag bits are parts of a packet
that determine what to do with the packet. The user may filter packets by filtering certain flag
bits within the packets, by checking the boxes corresponding to the flag bits of the TCP field.
The user may choose between urg (urgent), ack (acknowledgement), psh (push), rst (reset),
