  • 利用群晖NAS开启VPN服务
    闲言少叙。 第一步：在群晖NAS中安装VPN server，配置下NAS用户的vpn连接权限。 第二步：打开VPN server，提供三种VPN方式，PPTP，openVPN和L2TP，其中第一种iphone不再支持，而第二种openVPN对很多手机支持性都不好，所以选择第三种L2TP。启用L2TP，动态域名等等默认即可，主要需要设置的是密钥部分，设置好保存时会提醒要打开1701，400和4500端口。这个如果NAS是直接静态IP地址的话打开对应端口即可，不过多半是经过路由器了所以需要在路由器上添加端口映射。 第三步，在路由器上添加端口映射，不同路由器设置方式大体一样，只略微不同，不再详述。需要注意的是端口映射类型为UDP，另外对于L2TP类型三个端口都要添加。 第四步，其实完成第三步之后基本上已经完成了，打开客户端如iphone手机配置vpn，填写类型L2TP，域名地址，输入自己在NAS上的账号密码，以及刚才设置的密钥。连接即可。
