Awesome Miner requires a standard TCP/IP network connection in order to access the miners. If the miners are located on a remote site, the preferred solution is to setup a VPN network. Although it's possible to not use VPN and simply configure a router for port forwarding, it's not considered a good solution from a security point of view.
Another solution is to have Awesome Miner running on the remote site and access it via Remote Desktop. To get easy access to monitoring information at any time using any device, the Awesome Miner Cloud Services can be used, where Awesome Miner will be pushing monitoring statistics to the cloud.
