To specify a source, select the second choice and type a MAC address in valid MAC
address format (six hexadecimal character pairs).
Port

IP
Address/
Address
Prefix
Enter a source IP address in dotted decimal notation.
Specify the address prefix by entering the number of ones in the subnet mask.
A subnet mask can be represented by a 32 bit binary notation. For example, the subnet
mask “255.255.255.0” can be represented as “11111111.11111111.11111111.00000000”,
and counting up the number of ones in this case results in 24.
Socket

Note: You must select either UDP or TCP in the IP Protocol field before
you configure the socket numbers.
Select Any to apply the rule to all TCP/UDP protocol port numbers or select the second
option and enter a TCP/UDP protocol port number.
