Source network

Select this option to specify that the filter checks the network from which the packet is coming. You must also specify an IPv6 network address and prefix length.

Destination network

Select this option to specify that the filter checks the network to which the packet is sent. You must also specify an IPv6 network address and prefix length.

IPv6 address

Type the IPv6 address of the network from which the packet was sent or to which the packet is going.

Prefix length

Type the prefix length. The prefix is the part of the IPv6 address that indicates the bits that specify the network identifier.

Protocol

Lists the available protocol types upon which you can base a filter. The default is Any protocol. If you select Other, you must type a protocol identifier in Protocol number.

Source port

For TCP, TCP (established), and UDP protocols, type the port number specified by the source to be used by the filter. Some applications use well-known ports to send and receive packets. You can set a filter for one of these ports if you know which numbers the application uses for the protocol specified in Protocol. For example, you can try to block FTP traffic or allow only PPTP traffic.

Destination port

For TCP, TCP (established), and UDP protocols, type the port number used by the destination for the packet.

ICMP type

For the ICMP protocol, type the ICMP type number.

ICMP code

For the ICMP protocol, type the ICMP code number.

Protocol number

For the Other protocol, type the IP protocol number.
