My Look'n'Stop Ruleset

Here is the Look'n'Stop homepage

(The french version contains slightly more info, e.g. FAQ ;-)

Here you can even download the ruleset file. Note that I've changed all "My IP"s and MAC adresses to 0.0.0.0 resp. 00:00:00:00:00:00. Right now i've fixed a small problem in the Tracert rule: it was to filter on ICMP types all, 11 - now that's equal 11. Maybe i'll change some few things more - I'll tell you when. Ah yes, one more thing: in the downloadable .rls set, there is a loopback rule that up to now appears only in the table at the very bottom and not at all in the ruleset overview snapshot...

Note several things however:
  1. I have not added the "Termination Rules". They are the same as in the default ruleset.
  2. FTP is a tricky issue. Often - and especially if you're not using an FTP Client like CuteFTP, but rather your Browser's FTP or Getright, Go!Zilla, etc. - connections open up on totally arbitrary ports (in the range of local:1024-5000 however). I have not been able to cope with this up to now but rather am temporarily disabling TCP and General Termination Rules - very bad solution indeed...
  3. I have configured my IRC client to have its DCC Server listen on port 7700 and to use ports 7701-7800 for transfers.
  4. I have no idea what this hosts2-ns protocol is supposed to accomplish. It showed in my log when i wanted to download something from CNet...

There are infinitely more ressources at the Look'n'Stop Forum which is part of the Becky Users Forums.

There i found also the following rulesets:
