- **网段映射：** 当多个设备不同的局域网使用相同的内网网段（如`192.168.1.0/24`）存在冲突时，网段映射可以让你继续顺利的使用点对网和网对网，例如配置`192.168.188.0/24->192.168.1.0/24`，就可以使用`192.168.188.2`访问`192.168.1.2`。
- **应用层NAT：** 内置了使用`WinDivert`实现的应用层NAT，即使在`win7/8，win server2008/2012`这样的老系统无法使用系统NAT时也可以顺利使用点对网和网对网。
- **应用层防火墙：** 内置了防火墙功能，应用于虚拟网卡、端口转发、socks5，可以精细控制客户端的访问权限，例如只允许A访问B的3389，其它客户端无法访问
- **远程唤醒：** 可以通过`WOL魔术包、USB COM继电器、USB HID继电器`远程唤醒局域网内的设备
##### 其它特性
- **UI管理：** 简洁明了的web管理页面

1. 一些累计更新
2. 重建权限存储，ulong改为BitArray，同组所有客户端需保持版本一致
3. 增加唤醒功能，支持WOL，COM继电器，HID继电器
