cisco PIX防火墻怎么配置

  思科cisco依靠自身的技術(shù)和對(duì)網(wǎng)絡(luò)經(jīng)濟(jì)模式的深刻理解,使他成為了網(wǎng)絡(luò)應(yīng)用的成功實(shí)踐者之一,他制造的路由器也是全球頂尖的,那么你知道cisco PIX防火墻怎么配置嗎?下面是學(xué)習(xí)啦小編整理的一些關(guān)于cisco PIX防火墻怎么配置的相關(guān)資料,供你參考。

  cisco PIX防火墻配置的過(guò)程:

  PIX Version 6.3(1)

  interface ethernet0 auto 設(shè)定端口0 速率為自動(dòng)

  interface ethernet1 100full 設(shè)定端口1 速率為100兆全雙工

  interface ethernet2 auto 設(shè)定端口2 速率為自動(dòng)

  nameif ethernet0 outside security0 設(shè)

  定端口0 名稱為 outside 安全級(jí)別為0

  nameif ethernet1 inside security100 設(shè)定端口1 名稱為 inside 安全級(jí)別為100

  nameif ethernet2 dmz security50 設(shè)定端口2 名稱為 dmz 安全級(jí)別為50

  enable password Dv0yXUGPM3Xt7xVs encrypted 特權(quán)密碼

  passwd 2KFQnbNIdI.2KYOU encrypted 登陸密碼

  hostname hhyy 設(shè)定防火墻名稱

  fixup protocol ftp 21
