- **destination port (TCP or UDP header, transport layer)** - the destination port number indicates a port that the packet is sent to. Each service on the destination host listens to a port. Some well-known ports that might be filtered are 20/TCP and 21/TCP - ftp connection/data, 23/TCP - telnet, 80/TCP - http, and 53/TCP - DNS zone transfers.
- **connection status (TCP header, transport layer)** - the connection status tells whether the packet is the first packet of the network session. The ACK bit in the TCP header is set to “false” or 0 if this is the first packet in the session. It is simple to disallow a host from establishing a connection by rejecting or discarding any packets which have the ACK bit set to "false" or 0.
