Hi,

I think you need to create an manual binding on your router based on your clients IP address and MAC address.

Have a look through the following link which explains how to achieve this:

http://www.cisco.com/en/US/products/sw/iosswrel/ps1835/products_configuration_guide_chapter09186a00800ca75c.html

Plus you need to add the following command to stop your router from leasing out the IP address of your default-router and thus causing ip conficts

ip dhcp excluded-address 172.18.100.1

Good luck

Paddy
