Potreba za firewal?

Potreba za firewal.
Ovako na slackware 10.0 imam instaliran apache kao i mysql za projekte koje radim u localhostu ono za testiranje skripti i sl. I uglavnom na njima radim offline, rijetko online ali obadva servera su mi po defaultu pale tako da sam sve fino iskonfigurisao i rade vise nego ok. Prije određenog vremena sam onako iz dosada pregledao logove apache kad u access ima sta da i vidim:
-uglavnom mi javlja ovo

Uglavnom ima tu jos neki intresting stvari koje su zabiljezene, sredio sam .htaccess listu da nema niko pristup jedino ja u localhostu. Inace meni ovo ne smeta jel nema tu puno intresting stvari u localhostu, ali pitanje je kako nadu moj server iako na njemu onine nema nista.
Da li cu preko firewala srediti ovo, kontao sam da iptables nabacim ili nesto slicno da odradim.

Et imal neko neki savjet i malo explane ovog gore.
Poštovanje.

To su virusi (Nimda, Code Red i slično) ne obraćaj pažnju.

Ovo dvije stranice je nekakv mallo noviji bug u Apacheu 2.x cini mi se kad se Apache srusi na jako duge urlove… Ovo ti skripte rade, opale samo range IP adresa, pa se i tvoja potrefi…
