| [Kerio 4.x] Help with kerio
Whenever I have kerio running and I try to access a program from the quick launch menu or anywhere else, a little window pops up.
It's not from kerio it's from my system.
It says "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item."
How do I fix that? |

Cleveland, OH | Hi Mike,try disabling the system security module and see if that helps.If it does,in system security,settings check the automatically permit action. |

But, will that compromise my security at all?
Also, how do I configure kerio for ultimate security?
And how do I set it up for winmx? |

| Hi Mike,well I'm glad that disabling the security module worked.What you could do next is check in the system security and see if you allowed rundll32.exe to start,and if you allow it to launch other apps or you can always allow apps to start(automatically allow apps to start under settings in system security.:) |

My question is, how do I set it up for ultimate security?
Such as stealth and privacy and setting it up for winmx? |

| Hi Mike:I don't use winmx but from searching around I did find some rules,by setting your winmx rules to log you might be able to refine these:
winmx (out)TCP>any local port>remote ports-6699,7729-7735
winmx (in)UDP>any local port>remote port 6257
winmx (in)TCP>any local port>remote port 6699
winmx (out)TCP>any local port>remote ports:80-83,443,1080,3128,8080,8088,11523 |

| HI Mike,no need to feel sorry we all needed to start somewhere:)
The first thing is have you used a rule based firewall before?Rule based firewall are very good,giving you much control over ports,protocols,what app is allowed to connect to and how you allow it to do so.BUT it has to be configured correctly or it is just as bad as not having a firewall at all.
Now having said that if you are using your advanced packet filter rules,you must make sure you:right click on the Kerio icon in sys tray(by your clock) and go into configuration.Next goto Network Security>predefined and in the upper left hand side you will see the check box for the predefined rules,make sure the box is unchecked.Next go to the Applications tab and at the bottom right you will see the advanced packet filter tab,click on it and your now in Advanced Packet filter.If you click the add button(left hand side)you can now make your rule(s).I really suggest that you read the help manual that comes with Kerio,it will show you how to create the rules for Kerio.Also Blitzens rules for 2.1.5 can be used ,just make them in your advanced packet filter.You can also go to www.blarp.com to learn about rules also.
If this is to complicated (for the moment)you can use the simple filter rules(make sure the check box that you cleared has a check put back in it)and read,read,read the help files until it is easy for you(won't take that long once you start to experiment alittle).The simple rules are basically a permit,deny or ask and can be found in Network Security>Applications.Your predefined rules (one tab over)IGMP,Ping,Tracert and such are a allow or deny setup.
