Objective

A firewall is a security system which monitors and controls the flow of incoming and outgoing traffic to the network using configured security rules. The firewall serves as a barrier between a trusted, secure internal network and external untrusted networks.

The objective of this document is to show you how to configure firewall basic settings on the RV110W.

Note: For advanced configuration settings (such as enabling or disabling specific services in the firewall), refer to Firewall Service Management on RV110W.

Applicable Devices

• RV110W

Step 12. In the IPv6 Multicast Passthrough:(IGMP Proxy) field, check the Enable check box to enable multicast passthrough for IPv6.

Note: You may only enable this option if the device is configured to operate in an IPv6 mode on the Networking > IP Mode page.

Step 13. In the UPnP field, check the Enable check box to enable Universal Plug and Play (UPnP) which allows automatic discovery of devices that can connect to the router.

Note: If you choose not to enable UPnP, skip to Step 16.

Step 14. In the Allow User to Configure field, check the Enable check box to allow users to set port-mapping rules o.
