Best way to block a host attempting multiple url's on the WAF?

Louis-M

We have a host that is fairly persistent in trying various URL's on our WAF. Obviously not getting through but should we just leave it at that?

Or should we attempt to block or blackhole if even possible at all???

    Louis, as #2 in Rulz indicates, the solution is a blackhole DNAT.

    Hi Bob,

    I was looking at that and was going to give it a shot.

    Rule #2 is extremely important but I think it can get lost in the way it is presented in the rulz doc. I think it would be better if it was presented number wise eg 1. 2. 3. each on a different line

    It's probably the biggest gotcha out the lot when it comes to the FW and the proxy as the forum is littered with posts about traffic getting through/not being blocked when in fact its a mis-configuration issue due to not taking into account rule 2
