Hello.  My model wasn't in the drop down list.  I have the AC5400x router.  I would like to block a range of IP addresses that have been pounding at my firewall, owned by a Russian web company.  they are all incomming requests, going on 3 days now.  All from the same IP range.  They are being blocked, but the notification from my desktop firewall are driving me nuts.  I just want ot blcok the at the router.  Is this possible?
