Current Behavior

关联#594 ，在br-lan上的vlan-id为2的接口br-lan.2，lan_interface只绑定br-lan，wan_interface留空。当routing中将rfc1918 ip设置为must_direct，br-lan.2下局域网设备可以通过运行dae路由上的dns服务器正常工作，但直接使用公共dns则timeout。推测是vlan上的dns流量也被劫持到了dae0且没有得到正确处理。

Expected Behavior

vlan上的dns流量应遵守lan_interface绑定规则

Steps to Reproduce

添加vlan,分配防火墙

Environment

• Dae version (use dae --version): v0.7.0
• OS (e.g cat /etc/os-release): ImmortalWrt SNAPSHOT
• Kernel (e.g. uname -a): Linux ImmortalWrt 6.6.45
• Others:

Anything else?
