In "pass-by" deployment mode, WFilter can only block TCP traffic. To block UDP traffic, you also need to block certain UDP ports in your router or firewall.
For example: Tecent QQ works on udp port 8000 by default, it also can use tcp ports 80 or 443 to connect when this udp port is not available. So for completely blocking of tencent QQ, you also need to block udp port 8000 in your router/firewall.
