This package contains the Glacier2 router. A Glacier2 router allows you to securely route Ice communications across networks, such as the public Internet and a private network behind a firewall. With Glacier2, you only need to open one port in your firewall to make multiple back-end Ice servers reachable by remote Ice clients on the Internet.

Ice is a comprehensive RPC framework that helps you network your software with minimal effort. Ice takes care of all interactions with low-level network programming interfaces and allows you to focus your efforts on your application logic.
