Passive ftp kuralı hakkında



  • Arkadaslar selam;

    bazı ftp adreslerine baglanmaya calisildiginda ( 20 veya 21 portlarını kullanmayan ftp sunucuları) bağlantı problemi yaşıyorum.

    mesela ben 80 443  portları ftp portları  mail portları gibi belli portlara izin veriyorum ve kalanını engelliyorum.

    ama ftp portu olması gereken ftp hizmeti veren bazı adresler dynamic şekilde değişken portlardan hizmet veriyorlar ve bende bu portlar yasaklı oldugundan sıkıntı çıkıyor.

    örnek loglarım aşağıdadır. bu konuda çözüm yöntemi ne olabilir.
