Because you don't control the actual endpoint connecting you to the Internet, you can't effectively traffic shape.
After re-reading my post I realized that I misspoke. The dsl gateway is in the comm room and I do have access to it. Would prefer to have the pfSense server in my office but if I can't have it here, I can put it in the actual comm room. I have full control to the end point, the server location was just a preference. The gateway, on the other hand, can not be moved from the comm room.
Is it possible to shape traffic when the gateway provides the switch & wireless? I guess the problem is, it would look something like this:
Scenario 1: Internet > Gateway > pfSense
When it should probably look something like this:
Scenario 2: Internet > dslModem > pfsense > switch & wireless access point
Is the first scenario possible, or is only the second going to cut it? If only the second will cut it, I think we can use the gateway as a dsl modem by turning off the wireless.
