Could you give us more information? Toolbox, code and other details.
I use NARVAL toolbox for sending route request and route reply, but when I need to drop packets in case of malicious node I couldn't find any functionality that would support this in wired/wireless network.
Sorry but we do not have a solution for your query. You could mail \t\t\t\t\firstname.lastname@example.org or mail the toolbox author.
