Source
IP Enter a source IP address in dotted decimal notation.
Address/
Specify the address prefix by entering the number of ones in the subnet mask.
Address
Prefix
A subnet mask can be represented in a 32-bit 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.
Destination
IP Enter a destination IP address in dotted decimal notation.
Address/
Specify the address prefix by entering the number of ones in the subnet mask.
Address
Prefix
