这必须，需要改设置的，要改啥 dhcp options 的
我十年前干过，折腾完了索然无味，不知道现在有没有更新了
dhcp-option-force=125,00:00:00:00:10:02:06:48:47:57:2d:43:54:0a:02:20:00:0b:02:00:55
#This is used to convey the broadcast address, shall suppress it, otherwise the iptv will use this address as its ip address
dhcp-option=28
#Used to convey the domain name
#dhcp-option=15
这个里面有详细说明
