Command Usage

•All new rules are appended to the end of the list.

•Address bitmasks are similar to a subnet mask, containing four integers from 0 to 255, each separated by a period. The binary mask uses 1 bits to indicate “match” and 0 bits to indicate “ignore.” The bitmask is bitwise ANDed with the specified source IP address, and then compared

25.Includes TCP, UDP or other protocol types.
