Techie query?

This is on behalf of [livejournal.com profile] level_head, who cannot post it himself at the moment for reasons that should be obvious:

"I have a Netscreen 5XP. I'm getting barraged by someone attempting to add themselves as a user, literally more than one million times, using IPs from the outside, but would be within my subnet mask. The message that I get is "the user limit has been exceeded and (my subnet).xxx cannot be added". The "xxx" is being replaced with every possible entry in that subnet."

So, the request is: any ideas? Ideally, ways to make the attacker go AWAY. Any pain and suffering this might cause the attacker would be just fine, too.

My only guess would be that if it's a single IP address or a couple of them, to go into the device config and set up a filtering rule to simply ignore/drop any packets from those addresses. Probably under 'policies' or somesuch.
