Remember 'binary' - and .234 isn't binary. :) 20 (hosts) isn't, either. It'd be either 16 or 32. Which would be 255.255.255.240 or 255.255.255.224, respectively. -----Original Message----- From: windows2000-bounce@xxxxxxxxxxxxx [mailto:windows2000-bounce@xxxxxxxxxxxxx] On Behalf Of Ray at home Sent: Tuesday, March 23, 2004 07:05 PM To: windows2000@xxxxxxxxxxxxx Subject: [windows2000] Specify a range of IPs Hi list, I have to modify some IPSec rules to allow some communications for a range of IPs. I can do this by specifying an IP and a subnet that would equivalate to that range. I'm no subnetter, and I'm not sure how to do this. So, if this is the scenario: Allow connections for IPs xxx.xxx.xxx.0-20 For the IP and subnet mask, would I use: Xxx.xxx.xxx.0 and 255.255.255.234? Or am I just not getting it?
