You can view information about the status of interfaces by navigating to Status | Interfaces. Information about all interfaces is available here, including the following:

• The device name of the interface (for example, fxp0, em1, and so on)
• Interface status (Up or Down)
• The MAC address of the interface
• IP address, subnet mask, and gateway (for WAN-type interfaces)
• The number of packets that have passed (in and out), that have been blocked (in and out)
• The number of errors and collisions

If an interface has been configured to receive its IP address via DHCP (this is likely true for all WAN-type interfaces on your system), you can renew the DHCP lease via this page.
