思科路由器拨号上网配置教程思科路由器拨号上网配置教程图中路由器R1为出口路由器通过拨号连接外网，下面简单了解下如何通过它让客户端获取到ip地址并且能上外网：首先用超终端或CRT进入思科路由器配置模式，然后进行配置ipdhcpexcluded-address192.168.10.6192.168.10.254(dhcp中被保留不被下放的ip地址)ipdhcppoolabc(dhcp池的名字起为abc这个可以随意填写)network192.168.10.0255.255.255.0(dhcp下放的网段为192.1.10.x)default-router192.168.10.254(网关的设置)dns-server218.30.19.4061.134.1.4(dns的设置)vpdnenable(启用vpdn服务)interfaceDialer1(创建虚拟拨号接口1)ipaddressnegotiated(ip地址自动协商)ipmtu1492(因为ppp占8个字节所以为1492)ipnatoutside(启用nat转换服务并设置为外部接口)encapsulationppp(封装ppp协议)dialerpool1(为拨号池1)pppauthenticationpapcallin(设置ppp的'认证方式)pppchaphostnamexxxxx(宽带账号)pppchappassworda123456(宽带密码)ppppapsent-usernamexxxxxpassword123456interfaceFastEthernet0/0noipaddressduplexautospeedautopppoe-clientdial-pool-number1(将该端口加入到拨号池1中)InterfaceFastEthernet0/1ipaddress192.168.10.254255.255.255.0ipnatinside(启用nat服务并为内部接口)iproute0.0.0.00.0.0.0Dialer1(设置默认路由让走拨号端出去)ipnatinsidesourcelist1interfaceDialer1overload(使用nat转换将acl1中的地址用dialer1获取的公网地址转换)access-list1permit192.168.10.00.0.0.255(允许上网的网段)
