Overview
Overview
The service controller provides many configurable security features, including firewall,
authentication, and VPN (virtual private network).
This chapter describes how to use the firewall and manage security certificates.
Authentication options, previously on the Security menu are now found on the
Authentication menu. See Chapter 6: Authentication services, and Chapter 7: User
authentication.
VPN options, previously on the Security menu are now found on the VPN menu. See
Chapter 12: Working with VPNs.
For information on extending WPA termination from the AP to the service controller, see
Terminate WPA at the service controller on page 2-14.
Firewall
To safeguard your network from intruders, the service controller features a customizable
stateful firewall. The firewall operates on the traffic streaming through the Internet port. It
can be used to control both incoming and outgoing data.
A number of predefined firewall rules let you achieve the security level you need without
going to the trouble of designing your own rules. However, you can create a completely
custom set of firewall rules to suit your particular networking requirements, if necessary.
If the service controller is connected to a wired LAN, the firewall protects the wired LAN as
well.
