FSC Networking

  • Last updated on

The networking configuration for NextGen Secure Connectors (FSC) is configured either through the Secure Connector Editor (template, or directly for each device) or in Override mode in the web interface.

Automatically assigned FSC networks

The networks assigned to the LAN and Wi-Fi interfaces can be configured automatically by the Control Center or manually by the admin. In automatic mode, the Control Center will select the next free subnet in the FSC network and assign it to the LAN interface. The first IP address in the range is used as the management IP address, the second as the VIP address of the unit. The Wi-Fi interface also receives a free subnet from the FSC network.

FSC WAN connections

The FSC supports DHCP client, static IP addresses, and Wi-Fi client WAN connections. You can configure only one WAN connection per device.

For more information, see FSC WAN Connections.


The FSC1 includes Wi-Fi hardware. You can configure the FSC as an access point, or use Client mode to use the Wi-Fi as the WAN connection. Wi-Fi is supported for both 802.11b and 802.11g modes. In Access Point mode, the Control Center automatically assigns a network and starts the DHCP server. Devices connected to the access point do not use IP addresses from the FSC network. A SNAT access rule is needed to connect through the VPN tunnel or WAN interface.

For more information, see FSC Wi-Fi Access Point.

FSC routing

By default, the routing table allows the FSC to access the Internet and to communicate between Wi-Fi and the LAN, as long as these connections are also allowed by the on-device zone firewall. If you are using a static WAN connection, or require special routes, you can configure direct attached or gateway routes.

For more information, see FSC Routing.

FSC link selection

To use a backup connection when the primary Internet connection fails, you can configure a link selection policy. The Secure Connector probes the gateway or another explicit probing target and reroutes the traffic over the backup connection if the primary interface is down.

For more information, see FSC Link Selection.
