Hi,
Use the following subnetting to cover your range:
192.168.1.151/32
192.168.1.152/29
192.168.1.160/28
192.168.1.176/28
192.168.1.192/29
HTH, please do rate if it does help,

Mohammed,
Your access list should work fine but can be shrunk by one more line like this.
192.168.1.151 0.0.0.0
192.168.1.152 0.0.0.7
192.168.1.160 0.0.0.31
192.168.1.192 0.0.0.7

Interesting. Can I ask how you guys worked out the IPs & wild card masks that would be needed?

Hi Will,
Here's a subnetting tutorial http://www.ralphb.net/IPSubnet/subnet.html
Here's a nice subnetting utility to confirm if your subnetting it right http://www.boson.com/FreeUtilities.html

The best IP Subnetting, Supernetting/CIDR and VLSM page I have ever encountered is on a 3Com Website (Sorry, Cisco).
Please make a look into it and I'm sure you will never have to struggle with the IPv4 Addressing issues.
