Hello I've downloaded the Look'n'Stop free trial today and I just would like to know if according my description of what I have done I have done OK until now. I am not only a Look'n'Stop newbie but also very far from being a tech/computer geek and also a quite new Firewall user. After the installation I rebooted my PC and clicked on the "Authorize" button of the window that appeared on the screen each time I opened a program. After having opened Firefox, Thunderbird , MSN Messenger and Skype I finally started Emule and clicked on the Look'n'Stop "Authorize" button for eMule and eMule opened and seems to work with no problems. So far so good... Is that OK and enough for Look'n'Stop to work properly ? Apart from clicking to authorize is there anything I should configured manually ? I visited the Look'n'Stop website and saw the "Import Internet filtering rules" page and decide to download the "rules" for eMule and Skype and of course I "imported these rules on the Look'n'Stop' through -> "Internet Filtering" -> Import rules from a file. On the "Import rules from a file" window I was asked to check one or or two or three (?) "rules" and I did not know which one to check ? 1. The TCP . eDonkey-Client (allows to download files from the PC of a EDonkey user- authorizes the ports 4661 and 4665) 2. TCP eDonkey- (allows Edonkey users to download files from your computer and opens the port 4661 to 4665 of your computer for upload.) 3. UDP Emule- List of servers (allows to contact Emule servers on port 4672 ) As I have already said, my knowledge of technical computer stuff is minimal and so I have not the smallest idea what the "ports" (?) are or of the meaning of there numbers nor which one ( maybe all of them ?) among these rules I should pick. Another question about the same subject : the first time I used Look'n'Stop I clicked on the "Authorize" button for eMule and then eMule opened and worked OK; how differently will Look'n'Stop work once I import these "rule for eMule" . What will be different or "better" or "more secure" than before importing these rules ? How will Skype/Look'n'Stop work differently than before I imported the rules for Skype ? What if don't "import" any pre- made rules and just "authorize" new program the first time I am asked? Last question: I am ready to pay $39 for Look'n'Stop after the 30 days trial period but there are also many Free Firewalls ( Outpost Free version , Kerio Free version etc...) that received excellent reviews from many sources; what does Look'n'Stop give that Outpost Free version or Kerio Free version don't or an other payed product like "Outpost Pro" payed version. Thank you in advance.
