【正文】 部和外部端口 ip nat {inside | outside}   如下圖所示,     路由器的Ethernet 0端口為inside端口,即此端口連接內(nèi)部網(wǎng)絡(luò),并且此端口所連接的網(wǎng)絡(luò)應(yīng)該被翻譯,Serial 0端口為outside端口,其擁有合法IP地址(由NIC或服務(wù)提供商所分配的合法的IP地址),,經(jīng)由Serial 0口訪問Internet。命令ip nat inside source list 2 pool c2501 overload中的參數(shù)overload,將允許多個(gè)內(nèi)部地址使用相同的全局地址(一個(gè)合法IP地址,它是由NIC或服務(wù)提供商所分配的地址)。命令ip nat pool c2501 netmask 。   設(shè)置如下:   ip nat pool c2501 netmask   interface Ethernet 0   ip address   ip nat inside   !   interface Serial 0   ip address   ip nat outside   !   ip route Serial 0   Accesslist 2 permIT   ! Dynamic NAT   !   ip nat inside source list 2 pool c2501 overload   line console 0   exectimeout 0 0   !   line vty 0 4 end技術(shù)二五、配置靜態(tài)路由   通過配置靜態(tài)路由,用戶可以人為地指定對(duì)某一網(wǎng)絡(luò)訪問時(shí)所要經(jīng)過的路徑,在網(wǎng)絡(luò)結(jié)構(gòu)比較簡(jiǎn)單,且一般到達(dá)某一網(wǎng)絡(luò)所經(jīng)過的路徑唯一的情況下采用靜態(tài)路由。   任務(wù) 命令   建立靜態(tài)路由 ip route prefix mask {address | interface} [distance] [tag tag] [permanent]   Prefix :所要到達(dá)的目的網(wǎng)絡(luò)   mask :子網(wǎng)掩碼   address :下一個(gè)跳的IP地址,即相鄰路由器的端口地址。   interface :本地網(wǎng)絡(luò)接口   distance :管理距離(可選)   tag tag :tag值(可選)   permanent :指定此路由即使該端口關(guān)掉也不被移掉。     ,。由于在Router1上端口Serial ,,所以不需要在Router1上添加靜態(tài)路由。   Router1:   ip route   Router3:   ip route   ip route   同時(shí)由于路由器Router3除了與路由器Router2相連外,不再與其他路由器相連,所以也可以為它賦予一條默認(rèn)路由以代替以上的二條靜態(tài)路由,   ip route   即只要沒有在路由表里找到去特定目的地址的路徑,。     一、HDLC   HDLC是CISCO路由器使用的缺省協(xié)議,一臺(tái)新路由器在未指定封裝協(xié)議時(shí)默認(rèn)使用HDLC封裝。   1. 有關(guān)命令   端口設(shè)置   任務(wù) 命令   設(shè)置HDLC封裝 encapsulation hdlc   設(shè)置DCE端線路速度 clockrate speed   復(fù)位一個(gè)硬件接口 clear interface serial unIT   顯示接口狀態(tài) show interfaces serial [unIT] 1   注:.
