# Firewall Configuration

## Active

This allows to globally enable or disable the firewall. If the firewall is switched off the 4G Access Cube is not protected against attacks from the Internet.

The web-based firewall configuration allows restricting only outgoing connections. For incoming connections a builtin rule set is used.

## Services

This allows restricting access to services in the Internet (outgoing). "Allow all outgoing connections" allows unrestricted connection to servers in the Internet. "Allow these outgoing connections" disables all outgoing connections except for those found in the list.

In this list, each line requires you to specify a Name for the service which can be freely chosen, a Type for the service's protocol (either TCP or UDP) and Port for the port or port range to be allowed.
