Blocking ICMP on Plusnet Firewall

[#1]

Hi Folks,
Can the Plusnet broadband firewall be set to block ICMP? I'm getting ragged off by repeated distributed / coordinated ICMP activity against my static IP. It would be great to stop the activity before it reaches the target.

If you have a PN Technicolor router, it ignores them by default.  Otherwise if some is trying to hack/crash your router, log it and report it to PN/Police
