IP wizard does not support DHCP - enabled networks

Hi,

I am trying to configure Load Generators with multiple IPs using IP wizard and I am getting message "The IP wizard doesn't support DHCP enabled network cards". Do I need to get the static IPs for these generators? and what else do I need to take care of in order to set up IP Spoofing? And also when I look at the supported protocols for IP Spoofing I don't see WEB(Click and Script) but see Web(HTTP/HTML). Does this support Click and Script as well?

Thanks in advance!!
