Linux ping problem

Pozdravljeni!

Imam sledeč problem. Kr naenkrat je debiane nekaj zmešalo in ne gre več pingat Pa sploh nisem bil prijavlen v roota, ampak v usera. Napiše mi to:

PING www.amis.net (212.18.32.18) 56(84) bytes of data.

Ta linux deluje kot gateway, iz windows mašine pa pinga normalno. Pingat pa tudi gre windows mašino BP, samo navzven v internet ne gre pingat.Ma kdo kako idejo, kaj se je zgodilo? Nobenih sistemskih nastavitev nisem spreminjal in internet dela na linuxu, samo pingat ne gre

Probal sem že /etc/init.d/networking restart pa ni pomagalo.

P.S. Ipje sem tam pobrisal.

Hja maček dela svoje... Po pomoti sem zbrisal vrstico v rules od shorewalla

Zaklenite.
