Even if you block the traffic on your router/firewall, your WAN activity light will still blink because the packets are still coming across the wire. If you see a lot of WAN activity AND a lot of LAN activity, then you have something to worry about because that means the packets are getting through. WAN activity is normal - you just don't want to see that traffic on the other side of the router/firewall.
