 What is the purpose of the Gateway interface?
-**Answer**:
+**Answer**: A gateway interface allows two or more computers to use the Internet at the same time. While doing so, only the gateway's IP address will be visible on the Internet. The rest of the computers will be “hidden” behind the gateway. This is called IP masquerading.
