         注意，這里直接測(cè)試與10.0.1.1之間的連通性，顯示不通。使用擴(kuò)展ping，指定了發(fā)送數(shù)據(jù)包的源地址是10.0.2.2后，實(shí)現(xiàn)了連通性。原因是，直接發(fā)送數(shù)據(jù)包到10.0.1.1時(shí)，數(shù)據(jù)包的源地址到10.0.1.1時(shí)，數(shù)據(jù)包的源地址為10.0.20.2，該地址不屬于NAT轉(zhuǎn)換的客戶端地址范圍。

步驟六.將內(nèi)網(wǎng)服務(wù)器10.0.3.3發(fā)布出去

         配置內(nèi)網(wǎng)服務(wù)器10.0.3.3的telnet服務(wù)，映射到地址10.0.10.20

[FW]nat server protocol tcp global10.0.10.20 telnet inside 10.0.3.3 telnet

 

         在R3上開啟Telnet功能，并在R1上測(cè)試，測(cè)試時(shí)需要注意，對(duì)外發(fā)布的地址為10.0.10.20，所以R1對(duì)10.0.3.3訪問時(shí)，訪問的目標(biāo)地址為10.0.10.20。
