Greetings,
    This is what happens when you get a Port Scan + D/DoS Attack on your system:::
(On default). CFP  automatically blocks the suspicious host for about 5 minutes and CPF will stay on an emergency mode(blocking all traffic) for 120 secounds, whilst your system in still under attack!
 A Good feature isn't it? Yeah!

Here're the bugs:
1- After the attacks /or/ After time expires
Quote
- After this attacks, CPF does NOT return back to a secure/normal mode(still hangs on the emergency mode indefinately regardless of what settings you have under the "Instrusion Detection" Tab

**Exit CPF and re-open does NOT solve this issue**

Solutions:
-  Under the Security Tab --> Network Monitor --> Turn Off
-  Adjust security Level --> Allow All
-  A Reboot
  This does not look suitable for people running CPF on a SEVER Box, isn't it?

2- Another bug which I've already reported back at the days(~8months ago -IIRC).
Quote
- Activity - Logs - Max Log Size:: Change it to 100MB and then click on the "Connection Tab && back to the Logs Tab" ---> Max Log Size goes back to 5MB

Solutions:
- None for now.
- Or manage a 50MB log size


Affected Versions: All CPF prior to current: 2.4.18.184

Thanks,
rki.
