[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] RE: [FW1] IP address overlaps mask.
If you look at a network mask in binary, it must always be a series of 1's (the network part) on the left and the remaining bits on the right are 0's (the host part). In your example, 255.255.248.0 is0.00000000 When you look at the network number (IP address) of the subnet you are defining in binary, it can have 1's and 0's where the network mask has 1's, but where the network mask has 0's, the IP address must also all be 0's. In your case, .4.1.0 is xxxxx.0 and this shows that the 1 in xxx.4.1.0 is out of place. You might be wanting xxx.4.8.0 which is xxxxxxxx.0, but there many other possibilities, too. -----Original Message----- From: [email protected] [mailto:[email protected]] Sent: Wednesday, September 12, 2001 6:24 AM To: [email protected] Subject: [FW1] IP address overlaps mask. When trying to define a network in FW-1 4.0, i got a warning: Warning: IP address overlaps mask. I can't figure out why. Am I overlooking somthing here. The network object looks like this: Name: Some_network IP Address: xxx.4.1.0 Net Mask: 255.255.248.0 --- Jørn Yngve Dahl-Stamnes EDB Teamco, Trondheim [email protected] ============================================================================ ==== To unsubscribe from this mailing list, please see the instructions at http://www.checkpoint.com/services/mailing.html ============================================================================ ==== ================================================================================ To unsubscribe from this mailing list, please see the instructions at http://www.checkpoint.com/services/mailing.html ================================================================================
