华为USG系列IPSECVPN实施经验总结.docx

1、华为USG系列IPSECVPN实施经验总结一、网络环境介绍在清江酒店的USG防火墙调试IPSEC VPN的时候发现官方的配置手册有些问题，所以详细整理下实施过程出现的问题与解决方法。网络情况简介：清江酒店总部设在，等地有10个分支机构，只有总部可以确认为固定IP，分支机构无法确认，有的固定，有的用ADSL。本案例用2个分支介绍。了解了客户的根本网络状况后开始跟客户商量设计调试方案，选用IPSEC野蛮模式组网。在实施过程中发现以下问题：1、配置手册中IPSEC VPN配置实例不完善，NAT局部没有写要阻止VPN之间的数据访问做NAT转换，导致配置的时候不知道问题出在哪，在NAT中完善了转换策略后

2、，问题解决。2、因为野蛮模式配置是用ike local-name进展验证的，初步在IKE协商参数配置中参加了remote-name这项，配置完成后IPSEC VPN建立成功，分支和总部用网IP可以直接访问，第二天总部防火墙重启了一次后VPN怎么都建立不起来，打400后发现在IKE协商参数配置中使用了remote-name出现问题，导致VPN连接不上，去掉remote-name后问题解决。二、配置过程详细介绍下面详细介绍下配置过程，总部网用的172.16.1.0/24网段，其它分支采用192.168.X.X/24网段。防火墙的软件版本都是V100R005。一总部配置1、配置本地IKE本地用户名i

3、ke local-name qndc2、配置ACLacl number 3001 创建序号3001的高级访问控制列表rule 5 permit ip source 172.16.1.0 0.0.0.255 destination 192.168.1.0 0.0.0.255总部到分支1的网网段VPN触发策略rule 10 permit ip source 172.16.1.0 0.0.0.255 destination 192.168.2.0 0.0.0.255总部到分支2的网网段VPN触发策略3、配置IKE安全提议ike proposal 10 创建名称为10的IKE安全提议authentic

4、ation-algorithm md5 选择加密的算法为md54、配置IKE PEERike peer a 创建名称为a的IKE PEER exchange-mode aggressive 模式选择野蛮模式 pre-shared-key 123456 IKE协商的密钥为123456 ike-proposal 10 绑定IKE安全提议 undo version 2 选择V1的版本 local-id-type name 使用野蛮模式的IKE local-name验证 nat traversal 打开NAT穿越5、创建IPSEC安全提议ipsec proposal tran1 创建名称为tran1的

5、IPSEC安全提议 esp authentication-algorithm sha1 选择安全算法为哈希算法sha16、配置IPSEC安全策略模板ipsec policy-template map 1 创建名称为map的策略模板 security acl 3001 绑定触发ACL ike-peer a 选择前面创建的 ike-peer a proposal tran1 选择前面创建的IPSEC安全提议tran17、创建IPSEC安全策略ipsec policy map1 1 isakmp template map 创建名称为map1的IPSEC安全策略绑定map策略模板8、在外网接口上应用I

6、PSEC安全策略interface Ethernet0/0/0 ip address 119.97.240.106 255.255.255.248 ipsec policy map1 应用map1的IPSEC VPN策略9、配置目的地址为192.168.X.X/16网段不做NAT转换；这步不配的话网数据直接做NAT转换了，不会通过VPN隧道，那么前面的配置就白做了。nat-policy interzone trust untrust outbound 进入NAT配置视图 policy 1 策略1这是优先级，数字越小越优先 action no-nat 不做NAT转换 policy destina

12、要VPN主要配置都一样三配置总结总部和分之的配置区别在于，总部采用IPSEC安全策略模板绑定到外网接口，分之机构使用安全策略。完成所有配置后使用可以display ike sa、display ipsec sa 查看ike安全联盟状态和ipsec安全联盟状态；有这些信息就代表ipsec vpn连接成功。 三、详细配置文档现网成功稳定运行配置文档1、总部的配置文档#ike local-name qndc# firewall packet-filter default permit interzone local trust direction inbound firewall packet-fi
