OpenWrt系统wan和iptv通过vlan拔号失败，大神看看是什么问题

micr***

最近研究OpenWrt系统Wan和Iptv融合，OpenWrt拓扑图如下：


拔号成功如下图：




iKuai拓扑图如下：



以上配置中，设置光猫为桥接，OpenWrt的eth1接光猫的WAN口，eth2接光猫的Itv口，均能正常拔号并获取IP地址，设置好Udpxy代理后即可在内网中融合，上网与观看IPTV互不影响。
目前遇到的问题是，我想像iKuai系统一样把eth2网卡去掉，直接通过eth1网卡设置2个VLAN来进行PPPOE拔号，但遇到的问题是设置好以后只能有一条拔号成功，另一条无法拔号，但通过iKuai设置VLAN却可以正常拔号上网，说明光猫设置没有问题，是OpenWrt设置中可能存在不对的地方，特前来请教大神们分析一下OpenWrt下通过VLAN失败的原因。

以下是通过VLAN设置拔号图：


WAN连接上的情况：


IPTV连接上的情况：


WAN连接上，IPTV不能同时拔号的OpenWrt日志：


请大神们给分析一下，是什么原因不能像iKuai一样同时拔号？
纯粹就是技术交流！想弄清楚是什么原因。

日志截图全一点，首先拨wan的然后拨iptv的，再把日志截图出来wan和iptv的日志都要。你这个图里面提示的是eth1.3168已存在，应该是wan拨号占用了然后iptv拨号也要用这个所以拨号失败了。应该是vlan的原因系统没有正常生成出拨号对应的vlan所以两个拨号的都会使用同一个，然后先拨号的用了后拨号的就没有用的了所以就失败了。当然你这个日志没有截图全我也只是根据现有的推的。

先拔WAN,成功后再拔IPTV的完整LOG,
我阅读了一下，应该是这一句错误的原因：

终于解决了！
需要修改 /etc/config/network 文件，在里面增加一行 option macaddr 'XX:XX:XX' 来指定MAC地址即可！
