You guys have a cool terse way of discussing interesting things. :) I was
thinking that source routed packets was the answer to my question, and I
was also believing that they could be stopped. Do I need to care about
source routed packets if my upstream provider has everything configured
as they should? If I am using for example Linux, would it be enough to
configure the linux kernel to drop source routed packets? To configure the
linux firewall to ignore localnet packets from the external link?
Many questions.. I'll accept an RTFM answer if someone also tells me WTFM
is. :)
