关键命令: set peer {host-name [dynamic] ip-address} 说明: host-name 指定IPSec peer的DNS主机名称,如:myhost.example.com。 dynamic (可选参数) 指定 IPSec peer 的主机名在需要建立IPSec通道的时候才通过DNS服务器解释为IP地址。 ip-address 直接给出IPSec peer的IP地址(传统的配置方式)。 实际环境中局域网内应在一台机器上运行动态域名解释客户端程序,以将主机名nbo.3322.org注册到服务器,注册地址是路由器的外网端口地址。 version 12.3 ! hostname vpn-2 ! username mize password 0 http://mize.netbuddy.org no aaa new-model ip subnet-zero ! vpdn enable vpdn-group pppoe request-dialin protocol pppoe ! ip cef ip name-server 202.96.134.133 ! crypto isakmp policy 1 authentication pre-share group 2 crypto isakmp key cisco hostname nbo.3322.org ! crypto ipsec transform-set s2s esp-des esp-sha-hmac ! crypto map mymap 10 ipsec-isakmp set peer nbo.3322.org dynamic set transform-set s2s match address 110 ! interface FastEthernet0/0 no ip address pppoe enable pppoe-client dial-pool-number 1 ! interface dialer 1 ip address negotiated mtu 1492 encapsulation ppp ip nat outside dialer pool 1 ppp authentication pap callin ppp pap sent-username xxx password xxx crypto map mymap ! interface FastEthernet0/1 ip address 172.30.1.1 255.255.255.0 ip nat inside ! ip nat inside source route-map nonat interface dialer 1 overload ip classless ip route 0.0.0.0 0.0.0.0 dialer 1 ! access-list 110 permit ip 172.30.1.0 0.0.0.255 172.16.0.0 0.0.255.255 access-list 110 permit ip 172.16.0.0 0.0.255.255 172.30.1.0 0.0.0.255 access-list 120 deny ip 172.30.1.0 0.0.0.255 172.16.0.0 0.0.255.255 access-list 120 permit ip 172.30.1.0 0.0.0.255 any route-map nonat permit 10 match ip address 120 ! end |
