This very smart network guy at my work and I were talking about this: I'm using our company's wireless network, and trying to access our company site, specifically a link within our company webpage. The link won't work. But on our ethernet it will work. He says that it is impossible to "come back in the way you go out" due to loopback. Impossible?
I know a little about Spanning tree protocol. Is this what he's referring to? And is there really no way around that?
