Can't seem to test trigger alerts on the Intrusion Prevention. . . is it even working?

Hello all, 

We have a UTM 9 in the office and I was trying to test the Intrusion Prevention feature.

So under local networks I setup a host basically my computer. 

And on another computer I used a program called IDSWakeup to hit it with different kind of attack signatures. Test ran. 

But under live log I don't see anything in there. I set the attack pattern with no time limit . . .

Any ideas how to see this working?

Thanks

Andrew
