New to me that. Seems to be Ubuntu specific. Log and Stop Input chain 
apparently. See http://ubuntuforums.org/showthread.php?t=1197562

However, there is no mention of LSI in 
https://help.ubuntu.com/community/Firestarter nor did a search on 
http://www.google.com/custom?domains=www.fs-security.com&q=LSI&sa=Search&sitesearch=www.fs-security.com&client=pub-5302358671463440&forid=1&channel=&ie=ISO-8859-1&oe=ISO-8859-1&safe=active&cof=GALT:%23727272;GL:1;DIV:%23336699;VLC:727272;AH:center;BGC:FFFFFF;LBGC:CCCCCC;ALC:4B78AB;LC:4B78AB;T:000000;GFNT:233C55;GIMP:233C55;LH:43;LW:290;L:http://www.fs-security.com/pics/fs-logo2.jpg;S:http://www.fs-security.com/;FORID:1&hl=en

bring anything up.

However, the page on Firestarter was not too encouraging but I do not 
want to diss the hard work put into making what might well become a very 
good firewalling tool with a gui. It is up to you to decide whether you 
want to keep it on and decipher it/bug developers to make it work for 
you or to disable it and use UFW or build your own rules. I have no idea 
how linuxforum connections have triggered an alert/event to land in the 
LSI chain.
