I-Passive ye-Passive iyimodi ekhethiwe ye- FTP yamakhasimende we- FTP ngemuva kwe-firewall futhi isetshenziswa kaningi kumakhasimende e-web based based FTP namakhompyutha axhuma kuseva ye-FTP ngaphakathi kwenethiwekhi yenkampani. I-PASV FTP ibuye iphephile nakakhulu kuneFTP esebenzayo ngoba iklayenti

Ngokuvamile, kuyiseva ye-FTP eqala izicelo zedatha, kodwa lolu hlobo lokusetha lungase lungasebenzi uma i-firewall iklayenti ivimbele ichweba ukuthi iseva lifuna ukuyisebenzisa. Kungenxa yalesi sizathu ukuthi imodi ye-PASV yenza i-FTP "i-firewall-friendly".
