NG will let you do this -- Niels -----Original Message----- From: [email protected] [mailto:[email protected]]On Behalf Of Cepeda, Josh Sent: 17. september 2001 16:00 To: '[email protected]'; [email protected] Subject: RE: [FW1] IP address overlaps mask. Yeah I think firewall one sucks in that respect. You can only specify ip ranges when using NAT. -----Original Message----- From: [email protected] [mailto:[email protected]] Sent: Thursday, September 13, 2001 1:51 PM To: [email protected] Subject: RE: [FW1] IP address overlaps mask. I did not see that until all of you who replied to this message told me why I got the message. I guess I had to split the network object into several objects: .4.1.0 255.255.255.0 .4.2.0 255.255.255.0 xxx.4.3.0 255.255.255.0 xxx.4.4.0 255.255.252.0 xxx.4.8.0 255.255.248.0 It would have made things a lot easier if I could have used an address range in a rule (Source=Address-range). But it seems like that isn't possible, for some reason I can't understand. --- Jørn Yngve Dahl-Stamnes EDB Teamco, Trondheim [email protected] > -----Original Message----- > From: Good, Donald [mailto:[email protected]] > Sent: 13. september 2001 18:41 > To: '[email protected]'; > [email protected] > Subject: 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).
