Why does it have to be out-of-band? Seems complicated!

I'm a bit confused on this one. The entrepreneurial structure doesn't seem quite right, but I'm not sure if the matrix or divisional would be better. Guess I'll have to think it through carefully.

Okay, I think I know the answer here. The key is to configure a precise filter to allow only HTTP traffic between the EPG client and EPG server.

For these kinds of questions, I always try to think about what a real professional would do. Starting with general information and moving to specifics makes the most sense to me.
