However, I'm not sure how the echo server example is supposed to be configured - does it take *any* incoming echo request on the interface and reflect it back, or is this restricted to some subset of "for-us" packets (i.e., sent to "locally configured address")? Also, does the sender need a statically configured arp entry so that the echo request gets delivered? --Sowmini
