Hi everyone, Currently I am trying to implement Ethernet ARP module using IXP1200 in my project. Besides implementing ARP module, my project will focus on detect and prevention of ARP cache poisoning. My idea of implementing detect and prevention for ARP poisoning is by setting up a checker for both downward and upward of ARP request. hope to get some advices and ideas from this forum... btw, just wanna know, which reference design in workbench developer would be best suit this project?.. thanks.. Thanks. ===== Best wishes, Kuay, Chong Lee _______________________________ Do you Yahoo!? Win 1 of 4,000 free domain names from Yahoo! Enter now. http://promotions.yahoo.com/goldrush
