非歧视性语言

此产品的文档集力求使用非歧视性语言。在本文档集中，非歧视性语言是指不隐含针对年龄、残障、性别、种族身份、族群身份、性取向、社会经济地位和交叉性的歧视的语言。由于产品软件的用户界面中使用的硬编码语言、基于 RFP 文档使用的语言或引用的第三方产品使用的语言，文档中可能无法确保完全使用非歧视性语言。深入了解思科如何使用包容性语言。

关于此翻译

思科采用人工翻译与机器翻译相结合的方式将此文档翻译成不同语言，希望全球的用户都能通过各自的语言得到支持性的内容。请注意：即使是最好的机器翻译，其准确度也不及专业翻译人员的水平。 Cisco Systems, Inc. 对于翻译的准确性不承担任何责任，并建议您总是参考英文原始文档（已提供链接）。

简介

本文档说明如何使用预共享密钥来构建 IPSec 隧道以加入两个专用网络：

思科 VPN 3000 集中器 (192.168.1.x) 内部的一个专用网络。
检查点 4.1 防火墙 (10.32.50.x) 内部的一个专用网络。

假设在此配置开始之前，流量从 VPN 集中器内和检查点内流向互联网（本文档中用 172.18.124.x 网络表示）。

先决条件

要求

本文档没有任何特定的要求。

使用的组件

本文档中的信息基于以下软件和硬件版本：

VPN 3000 集中器
VPN 3000 集中器软件 2.5.2.F 版本
检查点 4.1 防火墙

本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您使用的是真实网络，请确保您已经了解所有命令的潜在影响。

规则

有关文档规则的详细信息，请参阅 Cisco 技术提示规则。

配置VPN 3000集中器

完成以下步骤，以配置 VPN 3000 集中器。

选择Configuration > System > Tunneling Protocols > IPSec > IKE Proposals > Modify以创建名为“des-sha”的Internet密钥交换(IKE)提议，该提议采用安全散列算法(SHA)散列、数据加密标准(DES)和Diffie-Hellman组1。将Time Lifetime保留为默认86400秒。

注意：VPN集中器IKE生命周期的有效范围为60-2147483647秒。
选择 Configuration > System > Tunneling Protocols > IPSec > IKE Proposals。选择 "des-sha" 并点击 Activate 以激活 IKE 提议。
选择 Configuration > System > Tunneling Protocols > IPSec LAN-to-LAN > Add。

使用检查点地址作为对等体，设置名为 "to_checkpoint" 的 IPSec 隧道。对于预共享密钥，请输入实际密钥。在 Authentication 下，选择 ESP/SHA/HMAC-160，然后选择 DES-56 for Encryption。输入 IKE 提议（本例中为 "des-sha"）以及本地网络和远程网络。
选择 Configuration > Policy Management > Traffic Management > Security Associations > Modify。确认“完全向前保密”处于禁用状态，并将 IPsec 生命周期保留为默认值 28800 秒。

注意：VPN集中器IPsec生命周期的有效范围为60-2147483647秒。
保存配置。

配置检查点 4.1 防火墙

完成以下步骤，以配置检查点 4.1 防火墙。

由于不同的供应商设置的 IKE 和 IPSec 默认生命周期存在差异，因此请选择 Properties > Encryption 以将检查点生命周期设置为与 VPN 集中器默认值一致。

VPN 集中器的默认 IKE 生命周期为 86400 秒（=1440 分钟）。

VPN 集中器的默认 IPSec 生命周期为 28800 秒。
"选择Manage > Network objects > New (或 Edit) > Network，配置Checkpoint后的内部 (""cpinside"") 网络的对象。"这应与 VPN 集中器中的“远程网络”一致。
选择 Manage > Network objects > Edit 以编辑 VPN 集中器在其对等体参数中设置的网关（"RTPCPVPN" 检查点）终端的对象。

在 Location 下，请选择 Internal。对于“Type”，选择 Gateway。在 Modules Installed 下，选中 VPN-1 & FireWall-1 并选中Management Station。
选择 Manage > Network objects > New (or Edit) > Network 以配置 VPN 集中器后部的外部 ("inside_cisco") 网络的对象。这应与 VPN 集中器中的“本地”网络一致。
选择 Manage > Network objects > New > Workstation，为外部 ("cisco_endpoint") VPN 集中器网关添加对象。这是 VPN 集中器的“公用”接口。

在 Location 下，选择 External。对于“Type”，选择 Gateway。

注意：请勿选中VPN-1/FireWall-1复选框。
选择 Manage > Network objects > Edit 以编辑 Checkpoint 网关端点（称为“RTPCPVPN”）VPN 选项卡。在域下，请选择其他然后从下拉列表中选择Checkpoint网络(称“cpinside”)。在被定义的加密机制下，精选的IKE，然后点击编辑。
更改 DES 加密的 IKE 属性，使其与 VPN 集中器中的 DES-56 和加密算法一致。
将 IKE 属性更改为 SHA1 哈希，以便与 VPN 集中器中的 SHA/HMAC-160 算法一致。
1. 取消选定积极模式。
2. 选中 Supports Subnets。
3. 在“Authentication Method”下，选中 Pre-Shared Secret。这与 VPN 集中器身份验证模式（预共享密钥）一致。
点击 Edit Secrets，以将预共享密钥设置为与实际 VPN 集中器预共享密钥一致。

isakmp key key address address netmask netmask
选择 Manage > Network objects > Edit 以编辑“cisco_endpoint”VPN 选项卡。在“Domain”下，选择 Other，然后选择 Cisco 网络内部（称为“inside_cisco”）。在被定义的加密机制下，精选的IKE，然后点击编辑。
更改 DES 加密的 IKE 属性，使其与 VPN 集中器中的 DES-56、加密算法一致。
将 IKE 属性更改为 SHA1 哈希，以便与 VPN 集中器中的 SHA/HMAC-160 算法一致。

更改这些设置：
1. 取消选择积极模式。
2. 选中 Supports Subnets。
3. 在“Authentication Method”下，选中 Pre-Shared Secret。这与 VPN 集中器身份验证模式（预共享密钥）一致。
点击 Edit Secrets，以将预共享密钥设置为与实际 VPN 集中器预共享密钥一致。
在策略编辑器窗口，插入源和目的为“inside_cisco”和“cpinside”(双向)这一规则。设置 Service=Any、Action=Encrypt 和 Track=Long。
在Action的选项下，请点击绿色的加密图标并且选择Edit Properties配置加密策略。
选择 IKE，然后单击 Edit。
在 IKE Properties 窗口中，将以下属性更改为与 VPN 集中器 IPsec 转换一致。

下面请变换，选择加密+数据完整性(ESP)。“加密算法”应为 DES，“数据完整性”应为 SHA1，“允许的对等体网关”应为外部思科网关（称为 "cisco_endpoint"）。Click OK.
配置 Checkpoint 之后，在 Checkpoint 菜单上选择 Policy > Install，使所做的更改生效。

验证

当前没有可用于此配置的验证过程。

故障排除

本部分提供的信息可用于对配置进行故障排除。

网络汇总

当多个相邻网络内部在检查点的时加密域配置，设备也许自动地总结他们关于关注数据流的情况。如果 VPN 集中器未配置为匹配，则隧道可能会出现故障。例如，如果 10.0.0.0/24 和 10.0.1.0/24 的内部网络已配置为包含在隧道中，则它们可能将汇总到 10.0.0.0/23。

VPN 3000 集中器调试

可能的 VPN 集中器调试包括 IKE、IKEDBG、IKEDECODE、IPSEC、IPSECDBG、IPSECDECODE。此调试是通过 Configuration > System > Events > Classes 中进行设置。

您可以通过 Monitoring > Event log > Get Log 查看调试。

选择 Monitoring > Sessions 以监视 LAN 到 LAN 的隧道流量。

选择 Administration > Administer Sessions > LAN-to-LAN sessions > Actions - Logout 以清除隧道。

Checkpoint 4.1 防火墙Debug

注：这是Microsoft Windows NT安装。由于已在“Policy Editor”窗口中将“Tracking”设置为“Long”，因此拒绝的流量应 Log Viewer 中显示为红色。可通过以下命令获取更详细的调试：

C:\WINNT\FW1\4.1\fwstop
C:\WINNT\FW1\4.1\fw d -d

并且在另一个窗口：

C:\WINNT\FW1\4.1\fwstart

发出以下命令以清除 Checkpoint 上的 SA：

fw tab -t IKE_SA_table -x
fw tab -t ISAKMP_ESP_table -x
fw tab -t inbound_SPI -x
fw tab -t ISAKMP_AH_table -x

在Are you sure?提示符处回答yes。
