特定的通信方之间在IP层通过加密与数据源验证等方式，来保证数据报在网络上传输时的私有性、完整性、真实性和防重放。
IPsec通过AH（Authentication Header，认证头）和ESP（Encapsulating Security Payload，封装安全载荷）这两个安全协议来实现上述目标，并且还可以通过IKE（Internet Key Exchange，因特网密钥交换协议）为IPsec提供自动协商交换密钥、建立和维护安全联盟的服务，以简化IPsec 的使用和管理。

SecPath高端防火墙二三层转发典型配置指
SecPath高端防火墙二三层转发配置举例关键词：二三层转发、PAT、私有地址、公有地址、地址池摘要：本文简单描述了高端多核防火墙二三层转发模块相关业务的特点，详细描述了二三层转发测试的基本方法和详细步骤，给出二三层转发基本的配置案例。
缩略语：目录1 介绍 (1)1.1 普通二三层转发的工作机制 (1)1.2 INLINE转发的工作机制 (1)1.3 跨VLAN二层转发的工作机制 (1)2 特性使用指南 (2)2.1 使用场合 (2)2.2 配置指南 (2)2.3 注意事项 (3)3 支持的设备和版本 (3)3.1 设备版本 (3)3.2 支持的设备 (3)4 配置举例 (4)4.1 组网需求 (4)4.2 设备基本配置 (5)4.3 二三层转发业务典型配置举例 (5)5 相关资料 (26)5.1 相关协议和标准 (26)5.2 其它相关资料 (26)1 介绍二三层混合转发包括了普通二三层转发、INLINE转发和跨VLAN二层转发。
1.1 普通二三层转发的工作机制如果设备接收到的报文目的MAC地址匹配三层VLAN接口的MAC，则通过设备的VLAN接口进行三层转发；否则通过设备的二层以太网接口进行二层转发。
普通的二三层转发是设备默认启用的特性，不需要配置。
1.2 INLINE转发的工作机制高端防火墙支持二层INLINE转发，即用户通过配置直接指定从某接口入的报文从特定接口出。
这种方式下，报文转发不再根据MAC表进行，而是根据用户已经配置好的一组配对接口进行转发，发送到设备的报文从其中一个接口进入后从另一个接口转发出去。
INLINE转发只支持二层接口，不支持逻辑接口，包括子接口；1.3 跨VLAN二层转发的工作机制跨VLAN二层转发，顾名思义，就是由数据链路层来完成不同VLAN间的通信。
目前这种技术主要应用在防火墙插卡上。
防火墙插卡是H3C为了适应灵活多变的网络应用而推出的新的防火墙形态。
防火墙插卡和交换机配合使用，经过交换机的二层网络流量由防火墙插卡过滤后再进行转发。

H3C SecPath UTM系列NAT典型配置举例关键词：NAT NAPT摘要：NAT（Network Address Translation，网络地址转换）是将IP数据报报头中的IP地址转换为另一个IP地址的过程。
在实际应用中，NAT主要用于实现私有网络访问公共网络的功能。
这种通过使用少量的公有IP地址代表较多的私有IP地址的方式，将有助于减缓可用IP地址空间的枯竭。

私有IP地址是指内部网络或主机的IP地址，公有IP地址是指在因特网上全球唯一的IP地址。
RFC 1918为私有网络预留出了三个IP地址块，如下：z A类：10.0.0.0～10.255.255.255z B类：172.16.0.0～172.31.255.255z C类：192.168.0.0～192.168.255.255上述三个范围内的地址不会在因特网上被分配，因此可以不必向ISP或注册中心申请而在公司或企业内部自由使用。
H3C SecPath防火墙系列产品混合模式的典型配置
H3C SecPath防火墙系列产品混合模式的典型配置
一、组网需求：
组网图中需要三台PC, PC1和PC4在Trust区域；PC2处于DMZ区域，其IP地址与PC1和PC4在同一网段，PC3位于Untrust区域，为外部网络。
G0/0接口和G1/0接口属于同一个桥组Bridge1。
对于访问控制有如下要求：
在防火墙G0/1接口上配置NAT，使Trust区域与DMZ区域通过地址转换才能访问Untrust区域；
通过NAT Server使DMZ区域对Untrust区域提供WWW服务；
在G1/0接口绑定ASPF策略并配合包过滤，使得Trust区域用户可以访问DMZ区域设备；但DMZ区域不能访问Trust区域；
在G0/0接口上绑定基于MAC地址的访问控制列表禁止PC4访问其他任何区域。
二、组网图：
支持混合模式的产品型号有：Secpath F1000-A/F1000-S/F100-E/F100-A；版本要求Comware software, Version 3.40, ESS 1622及以后。
四、配置关键点：
1、每一个桥组都是独立的，报文不可能在分属不同桥组的端口之间
传输。
换句话说，从一个桥组端口接收到的报文，只能从相同桥
组的其他端口发送出去。
防火墙上的一个接口不能同时加入两个
或两个以上的桥组。
2、要实现不同桥组之间或二层接口和三层接口之间数据转发，需要
创建桥组虚接口，并且将桥组虚接口加入到相应的区域。
