BFW 3.x reduces 3G speed 10x [INACTIVE]

[Iuo]

Hi
I have a problem with a 3G connection speed with Huawei E272 USB modem.

If I connect directly to my computers it works ok and speedtest gives me download speed 5,5 Mbit/sec
But if I connect through BWF 3.246 the speed reduces 10 times and the download speed is only 0,5 Mbit/sec
