 ### 更多玩法
 
 1. 和远程桌面(如mstsc)搭配，超低延迟的体验
 2. 安装samba服务，共享磁盘
 3. 搭配公网服务器nginx反向代理，在公网访问本地文件

 - NAT穿透

 ### Todo
 - 支持安卓
 - 数据加密
 
+### 常见问题
+#### 问题1: 设置网络地址失败
+##### 可能原因:
+switch默认使用10.26.0.0/24网段，和本地网络适配器的ip冲突
+##### 解决方法:
+1. 方法一：找到冲突的IP，将其改成别的
+2. 方法二：自建服务器，指定其他不会冲突的网段
+3. 方法三：增加参数--device-id，设置不同的id会让switch-server分配不同的IP，从而绕开有冲突的IP
