It should not make a difference as long as you do not use rules. I think in your situation, the router is asking the ARP request because an application/socket bound to the wrong address tries to contact a host in your upper network. Therefore the auto binding of the local address will not take place. Have a look at the "netstat -tupe" output, right after the arp request. You will see most likely a established TCP connection or UDP request. You can also tcpdump for them.
