Although it is technically possible for a client machine to obtain a license from a remote license server across a wide area network (WAN), this is not a supported mode of operation for ARM development tools and we strongly discourage you from attempting to do it. When setting up your licensing system, you should ensure that client machines have access to local license servers (i.e., across your site's local area network (LAN)).

If you do attempt to use a WAN server, the additional network delays connecting to the server will dramatically increase the time taken by the ARM build tools to build your code. In many cases builds may actually fail if the time delays caused are too great. The high license traffic caused  will also greatly increase the traffic on your WAN, which could lead to more general problems on your network.
