PIX防火墻配置實(shí)例

1、如下圖所示：這是一家小型公司，為了公司不被攻擊，則買了一臺(tái)放火墻。(PIX802.bin) 要求：1、 內(nèi)網(wǎng)通信無(wú)阻。2、 在放火墻處做NAT轉(zhuǎn)換。4、 在做一些安全上的配置，此配置不列出，參考cisco 安全技術(shù)（教科書(shū)）第八章內(nèi)容。5、 保存配置。R1(config)#do show runBuilding configuration.Current configuration : 975 bytes!version 12.4service timestamps debug datetime msecservice timestamps log datetime msecno servic
