That's probably optional. But if
you have the router resources to do it.
every little bit helps. You
probably should filter and log it, to find out
why one of your hosts is
trying to send to a 1918 address outside your
site - if you're not using 1918
space, it shouldn't happen, and if you ARE
using it, the packet should have
ended up inside your net, not on your
border router.
Which is quite true, but there are a lot of
people out there still using hubs, which (along with improperly configured NATs)
probably explains the origins of a lot of this traffic. Which brings me to
my point - some of us are actually grateful for having our Private (pun
intended) packets filtered while we were setting up a
network.
