The router finds the hardware (or MAC) address by broadcasting a request
to the network. It basicly asks "Does anybody here know what the MAC
address is for the interface <ip-address>." and someone will respond with
it.
As for your routing problem ... do you have a "real" IP address assigned
to that laptop? If you are using something like 192.168.x.x it is not
going to work. Also, you need to use an IP address that is part of the
network that the router is set up to route for. If you try to give it
just any IP address, maybe one you have been given by an ISP for a
dedicated dialup, the router will most likely ignore it because it is
outside the range of the network that it routes data for.
