Intrustion Prevention

Hey Ladies and Gents.

I am having a little problem with my symantec endpoint protection 12.1..

Symantec is blocking port scanning, i have tried to exclude an ip address from the Intrustion Preventiopn policy..

Unfortunatly symantec keep blocking the portscan after i have excluded it.. I also tried turning off the Intrusion Prevention Policy.. But it still doesn't work..

The firewall policy is not enabled..

Any tips will be really appreciated :)

Thanks

Shane
