Agreed. Since the OP was presented with conflicting info I simply provided a little "training" to let the OP know that I actually know WTF I'm talking about (sometimes) and that /29 will work. When all else fails, try it and see what happens! ----- Original Message ----- From: freeradius-users-bounces+ggatten=waddell.com@lists.freeradius.org <freeradius-users-bounces+ggatten=waddell.com@lists.freeradius.org> To: FreeRadius users mailing list <freeradius-users@lists.freeradius.org> Sent: Fri Aug 21 02:15:31 2009 Subject: Re: NAS IPs Gary Gatten wrote:

If I understand you correctly – I respectfully submit you are incorrect. When using VLSM / classless masks to define a NETWORK, you are correct (I haven’t checked the math – just assuming you are correct). However, when defining ACL type stuff, the proposed /29 would be perfectly OK. That said, I’m speaking strictly of my experience with routers, firewalls, etc. If FR supports this I can’t say for sure.

you can not to use /29 for 8 IPs because 3 bits have exactly 8 combination ,..x000 is the network and ...x111 is the difusion ,then really you have 6 IPs with /29, you need /28 16 combinations minus two,min 14 IPs for 8 numbers.

I think we should stop the TCPIP training. This is the freeradius list. The user wants to know if /29 can be used. The answer is yes. -- Johan Meiring Cape PC Services CC Tel: (021) 883-8271 Fax: (021) 886-7782 - List info/subscribe/unsubscribe?
