ISDN訪問首都在線 263網(wǎng)實(shí)例 : 本地局部網(wǎng)地址為 ,屬于保留地址，通過 NAT 地址翻譯功能，局域網(wǎng)用戶可以通過 ISDN上 263 網(wǎng)訪問 Inter。 263 的 ISDN 電話號碼為 2633，用戶為 263，口令為 263，所涉及的命令如下表： 任務(wù) 命令 指定接口通過 PPP/IPCP 地址協(xié)商獲得 IP地址 ip address negotiated 指定內(nèi)部和外部端口 ip nat {inside | outside} 使用 ppp/pap 作認(rèn)證 ppp authentication pap callin 指定接口屬于撥號組 1 dialergroup 1 定義撥號組 1允許所有 IP協(xié)議 dialerlist 1 protocol ip permit 設(shè)定撥號，號碼為 2633 dialer string 2633 設(shè)定登錄 263的用戶名和口令 ppp pap sentusername 263 password 263 設(shè)定默認(rèn)路由 ip route bri 0 設(shè)定符 合訪問列表 2的所有源地址被翻譯為 bri 0所擁有的地址 ip nat inside source list 2 interface bri 0 overload 設(shè)定訪問列表 2，允許所有協(xié)議 accesslist 2 permit any 具體配置如下： hostname Cisco2503 ! isdn switchtype basic3 ! ip subzero 26 no ip domainlookup ip routing ! interface Ether 0 ip address ip nat inside no shutdown ! interface Serial 0 shutdown no description no ip address ! interface Serial 1 shutdown no description no ip address ! interface bri 0 ip address negotiated ip nat outside encapsulation ppp ppp authentication pap callin ppp multilink dialergroup 1 dialer holdqueue 10 dialer string 2633 dialer idletimeout 120 ppp pap sentusername 263 password 263 no cdp enable no ip splithorizon no shutdown ! ip classless ! !
