You'll need to do an HQoS shaper on the inside fastethernet interface in order to shape remote traffic so that they fall back. You're giving 50 percent priority to a 4.6Mbps link, on a 100Mbps interface or have you configured the correct bandwidth statement on it. I've found using HQoS tends to fix things to a point.
