你好，我的防火墙型号是H3C SecPath F1000-AI-35，H3C Comware Software, Version 7.1.064, Release 8860P1211。 目前的拓扑接口：最上面是卫生专网，下面依次是防火墙、内网核心。 卫生专网接在防火墙的3口（11.73.0.36/29），防火墙的1口往下接在内网核心，配置见附件。
现要求卫生专网中的11.73.0.19服务器A能访问医院内网中的192.192.192.22的服务器B，现状是B能ping通A，但Aping不通B。 请看下配置再指点，辛苦！
问题1：若要求A能访问B，是不是可以在A的出口设置ip route-static 192.192.192.22 255.255.255.255 11.73.0.36？这样卫生专网可以直接访问到192.192.192.22吗？
问题2：如何把服务器B的IP映射到11.73.0段上？防火墙的域间策略如何设置，请详细说下具体配置。
问题3：卫生局那边给了一个专网地址11.73.0.35 255.255.255.248 11.73.0.38，说是可以启用服务器B的双网卡，拉一根网线插到防火墙上，但防火墙往专网的线已经被3口占用，假如我有一根网线把服务器B的第二个网卡连到防火墙的12口，把服务器B的第二网卡设成11.73.0.35的IP，是不是应该把防火墙的3口和12口都改成二层，然后起个vlan 100，interface vlan 100 ip add 11.73.0.36/29，然后把这两个口划到vlan100下，这样是否可以？如果可以的话，麻烦写下具体配置，原来的配置有nat outbound等等。万分感谢！！！

最佳答案
你的这个需求是典型的源地址转换和目的地址转换应用，首先把专网的相关信息梳理清楚：
1、11.73.0.35/255.255.255.248 /11.73.0.38为分配给这个单位的IP地址，可以设置在防火墙的外部端口上，其中11.73.0.35为IP地址，255.255.255.248为子网掩码，11.73.0.38为网关
2、11.73.0.36可以规划为卫生专网内部192.192.192.22的外部映射地址；
3、防火墙上至少由以下配置：
# ip route-static 0.0.0.0 0.0.0.0 11.73.0.38 假如没有其他外部链路的话，可以用0.0.0.0缺省路由
#acl basic 2001
rule 0 permit source 192.192.192. 0 0.0.0.255
#interface GigabitEthernet1/0/3
ip address
11.73.0.35 255.255.255.248
nat outbound 2001
nat server protocol tcp global 11.73.0.36 端口 inside 192.192.192.22 端口
#
除了这个基本配置外，需要在防火墙上配置安全策略，可参照以下链接http://www.h3c.com.cn/cn/Service/Document_Software/Document_Center/Home/Security/00-Public/Configure/Web_Configure/H3C_WCG(V7)-6W302/07/?CHID=547855

在3口上配置nat server global 要映射的地址 inside 192.192.192.22
如果要双向访问就在最后边机上reversible

我去，这没法看，算了，别看了。。。。
我本来想上传个附件，结果上传了总是不显示，真无语。
问题二：推荐用安全策略，转目的方向，放通源到转换后的IP，反向转源，放通转换前的源地址； 问题三：二层口不能配置NAT

你好，3接口上已经有IP了，ip address 11.73.0.36 255.255.255.248。以前他这边有个傻瓜交换机，专网线接在傻瓜上，然后傻瓜出一根线接在防火墙的3口，然后另一个线接在服务器上，服务器上的IP设置成11.73.0.35，这样是额可以的。但现在不想再加个傻瓜。就是想服务器直连到防火墙上，如何设置相当于加了一个傻瓜交换机
