Then what do you need proxy-arp for? Without it, your cablemodem will only
see the routers MAC address.

Bridging is the similar to routing, only on layer 2, i.e. ethernet. A switch
is nothing else.

Proxy-arp does do something similar to bridging. Probably not the same, but
I am not exactly sure about it. Is anyone?
