Hello, I think you are not using the mask correctly?
ACLs are using the mask in a different way: the "255" means strict compliance with the octet in the IP address, when "0" means ignore the corresponding octet.
In more technical way, for IP ACLs (from the ? help button in the IT GUI): When "IP Address" radio-button is selected, enter an IP address with relevant wild card mask to apply this criteria. Wild card mask determines which bits are used and which bits are ignored. A wild card mask of 0.0.0.0 indicates that none of bits are important. A wild card of 255.255.255.255 indicates that all of the bits are important.
