Easy way to verify this is throw the -e flag into tcpdump - it'll print the
MAC addresses of the tx/rx ethernet interfaces... If the "to" addr isn't
the one of your ethernet card (or more to the point, it IS the one of the
ethernet card that you originally obtained a working lease from), that
pretty much proves that's the problem.
Now if I could just figure out why one of my DSL providers keeps getting the
MAC address for the >inside< ethernet card of my firewall for some (not all)
IPs...
