One of the most important features in eBox is its firewall module. You can access it through Firewall . There you can make packet filtering (Section 5.3) or port redirection (Section 5.2).

The firewall has different behavior with external or internal network interfaces.

The internal interfaces are connected to local networks. They had not restrictions as the external interfaces have.

The external interfaces are connected to external networks and eBox only allows redirections from them.
