Simple question, but thus far my searches have been unable to yield a suitable answer:

Can I bridge my WiFi and Ethernet adapters, such that the device connected on the Ethernet port is visible to the network the WiFi adapter's on - i.e., traffic is passed through to/from the Ethernet port?

Note this is not 'Internet Sharing'.

802.11 doesn't permit multiple MAC addresses to come from a single endpoint. To do bridging, you have to use something like WDS. I'm not sure if a Mac has the ability to serve as a WDS peer and your AP/router has to support it.

The answer depends on your definition of "bridge." A lot of times people say "bridge" when what they really are talking about is an OSI Model Layer 3 router. In any case this article should get you pointed in the right direction. http://www.glassechidna.com.au/2009/projects/mac-os-x/xbridge/xbridge-network-bridging-in-os-x/
