I have a asa5510 with asa ver7.2. I would like to know if its possible to add a network group object specifying ip address range eg 192.168.0.1-192.168.0.100 instead of specify the entire subnet. I have explore the asdm and it seem the only way is to add the addresses 1 by 1 into the network group object. Is there a more efficient way? Pls advise. Thks in advance.
