I'm not familiar with that router firmware but there should be an option in the firewall settings to block ICMP requests. I'm pretty sure my last Netcomm ADSL/Router had that option.

You could block ICMP via UFW but, that will not stop your router responding to the requests, only the Lucid system. And unless you're running a DMZ directly to said box for some reason, that won't achieve what you want.

As a side note, you may want to see if there is a firmware update available.
