如果他们的 IP 必须与他们的桌面相同，那么正确执行此操作的唯一方法是让他们通过 VPN 将 RDP 连接到他们的桌面上。

或者修复有这个荒谬要求的软件

您可以使用 openvpn 轻松完成此操作。除了他们网站上的非常好的文档之外，互联网上还有很多示例。请注意，您需要设置一个 tap 隧道才能将它与您的 lan 桥接，而不是一个 tun 隧道，它是路由的。 http://openvpn.net/index.php/open-source/documentation/howto.html#examples 如果您需要更多帮助而不是联系我，我可以与您分享我的工作配置。

不能解决您的直接问题，但鉴于您的标题，LISP 绝对允许用户在各种“区域”中拥有一个 IP 地址，尽管它对于工作/家庭使用来说可能仍然有点复杂。

What is LISP?

LISP is a network architecture and set of protocols that implements a new semantic for IP addressing. LISP creates two namespaces
and uses two IP addresses: Endpoint Idenfitiers (EIDs), which are assigned to end-hosts, and Routing Locators (RLOCs), which are 
assigned to devices (primarily routers) that make up the global routing system. Performing this separation offers several advantages,
including:
- Improved routing system scalability by using topologically-aggregated RLOCs
- Provider-independence for devices numbered out of the EID space (IP portability)
- Low-OPEX multi-homing of end-sites with improved traffic engineering
- IPv6 transition functionality
- IP mobility (EIDs can move without changing - only the RLOC changes!)
LISP is a simple, incremental, network-based implementation that is deployed primarily in network edge devices. 
It requires no changes to host stacks, DNS, or local network infrastructure, and little to no major changes to 
existing network infrastructures.
