The answer is NO. While defining access-lists you have to use wildcards, meaning that the range you are using must be blocks in 2^n (2 powered by n). Wildcards difine the important and non-important bits is the IP address. They use the same method and algorithm subnet masks use but in a reverse manner. In a subnet mask you define the important bits ( the bits which you want to exactly the same the IP address) with ONES, and the non-important bits with ZEROs. In wildcards, you define the important bits with zeros, and the non-important bits with ones. For the same reson you cannot have a network address with 37 hosts, you cannot define a access-list with a wildcard to include 37 contigous addresses. Here is an example: if you want to define an access-list for 11001101.01011101.1110001010.11010111 and you want all the bits to be same but the last 3 bits your mask will be: 00000000.00000000.00000000.00000111 (0.0.0.7) Hope this helps, Hamid
