[转贴]非固定ip地址的ADSL访问路由器配置

yaaaa

这个配置比起原来的有固定ip地址的配置要难很多，要考虑到方方面面的东西，在这里，大家可以少走弯路了：\r\nvpdn enable\r\nno vpdn logging\r\n!\r\nvpdn-group pppoe\r\nrequest-dialin \r\nprotocol pppoe \r\n!\r\ninterface Ethernet0\r\nno shut\r\nip address <ip address>; <subnet mask>;\r\nip adjust-mss 1452\r\nip nat inside \r\nno ip directed-broadcast\r\n!\r\ninterface ATM0\r\nno shut\r\nno ip address\r\nno ip directed-broadcast\r\nno atm ilmi-keepalive\r\nbundle-enable\r\n!\r\ninterface ATM0.1 point-to-point\r\nno ip directed-broadcast\r\npvc <vpi/vci>;\r\npppoe-client dial-pool-number 1 \r\n!\r\n!\r\ninterface Dialer1\r\nip address negotiated\r\nmtu 1492\r\nip nat outside \r\nencapsulation ppp\r\ndialer pool 1\r\nppp chap hostname <username>;\r\nppp chap password <password>;\r\nppp pap sent-username <username>; password <password>;\r\n! \r\nip nat inside source list 1 interface Dialer1 overload \r\n!\r\nip classless \r\nip route 0.0.0.0 0.0.0.0 dialer1 \r\naccess-list 1 permit <ip address of ethernet0>; 0.0.255.255

用CISCO本身就是一个大弯路。\r\n\r\n在Linux上，缺省路由可以不是网关，而是一个网卡，比如：\r\nroute add default ppp0\r\n\r\n就可以让ppp0成为缺省路由，而不管它是静态IP还是动态IP。
