Have a look at Click's FAQ http://www.read.cs.ucla.edu/click/faq , there's
an item that explains how to search the Click mailing list.
" Use Google search with the site:amsterdam.lcs.mit.edu tag."

I cant comment on the fakeip-router.click as I have never used it.

Click's kernel mode queue element can only handle a maximum of around 32k
packets due to the kernel's kmalloc limit. I posted a BufferQueue element
the other week that overcomes this by using vmalloc instead. I successfully
run a 500k queue in kernel mode. Let me know and I'll mail it off the list
to you.

2. I created a configuration for a router using the make-ip-conf.pl. I need
