组网及组网描述：
，在内网主机上是可以正常访问服务器的端口的，在外网上是无法访问服务器端口，在防火墙上直接telnet 服务器的端口也是不通的

最佳答案
1.更换外部端口号9000或者一万以上的，小端口号可能被运营商禁掉
2.安全策略是否调用ipv4地址对象组和服务对象组
参考配置案例
3.1 配置内部服务器映射（端口映射）
#在外网口填写运营商提供的公网地址，掩码，配置映射，映射端口8081，服务器地址192.168.1.88
<H3C> system-view
[H3C] interface GigabitEthernet1/0/1
[H3C-GigabitEthernet1/0/1]ip add 202.1.1.100 255.255.255.248
[H3C-GigabitEthernet1/0/1]nat server protocol tcp global 202.1.1.100 8081 inside 192.168.1.88 8081
[H3C-GigabitEthernet1/0/1]quit
#在内网口配置映射,填写内网网关地址以及配置Nat Hairpin
[H3C]interface GigabitEthernet1/0/4
[H3C-GigabitEthernet1/0/4]ip add 172.16.100.1 255.255.255.0
[H3C-GigabitEthernet1/0/4]nat hairpin enable
[H3C-GigabitEthernet1/0/4]quit
Nat Hairpin功能简介：通过在内网侧接口上使能NAT hairpin功能，可以实现内网用户使用NAT地址访问内网服务器或内网其它用户。NAT hairpin功能需要与内部服务器（nat server）、出方向动态地址转换（nat outbound）或出方向静态地址转换（nat static outbound）配合工作，且这些配置所在的接口必须在同一个接口板，否则NAT hairpin功能无法正常工作。
3.2 安全策略配置
防火墙目前版本存在两套安全策略，请在放通安全策略前确认设备运行那种类型的安全策略？以下配置任选其一。
1. 通过命令“display cu | in security-policy”如果查到命令行存在“security-policy disable”或者没有查到任何信息，则使用下面策略配置。
[H3C]display cu | in security-policy
security-policy disable
#创建地址对象组，地址对象组名称为OA服务器
[H3C]object-group ip address OA服务器
[H3C-obj-grp-ip-OA服务器]network host address 192.168.1.88
[H3C-obj-grp-ip-OA服务器]quit
#创建服务对象组，服务对象组名称为8081端口，目的端口8081
[H3C]object-group service 8081端口
[H3C-obj-grp-service-8081端口]service tcp destination eq 8081
[H3C-obj-grp-service-8081端口]quit
#创建IPv4对象策略，策略名称为OA服务器，放通目的地址为192.168.1.88的8081端口
[H3C]object-policy ip OA服务器
[H3C-object-policy-ip-OA服务器]rule 0 pass destination-ip OA服务器 service
8081端口
#创建安全策略，源安全域为Untrust目的安全域为Trust，应用创建的IPv4对象策略
[H3C]zone-pair security source Untrust destination Trust
[H3C-zone-pair-security-Untrust-Trust]object-policy apply ip OA服务器
[H3C-zone-pair-security-Untrust-Trust]quit
#创建IPv4对象策略，策略名称为互通,规则为允许
[H3C]object-policy ip 互通
[H3C-zone-pair-security-互通]rule pass
[H3C-zone-pair-security-互通]quit
#创建安全策略，源安全域为Trust目的安全域为Trust，放通内网到内部服务器的访问数据
[H3C]zone-pair security source Trust destination Trust
[H3C-zone-pair-security-Trust-Trust]object-policy apply ip 互通
[H3C-zone-pair-security-Trust-Trust]quit
2. 通过命令“display cu | in security-policy”如果查到命令行存在“security-policy ip”并且没有查到“security-policy disable”，则使用下面策略配置。
[H3C]display cu | in security-policy
security-policy ip
创建安全策略并放通源安全域为Untrust目的安全域为Trust，放通外网访问OA服务器的8081端口策略；
#创建地址对象组，地址对象组名称为OA服务器
[H3C]object-group ip address OA服务器
[H3C-obj-grp-ip-OA服务器]network host address 192.168.1.88
[H3C-obj-grp-ip-OA服务器]quit
#创建服务对象组，服务对象组名称为8081端口，目的端口8081
[H3C]object-group service 8081端口
[H3C-obj-grp-service-8081端口]service tcp destination eq 8081
[H3C-obj-grp-service-8081端口]quit
创建安全策略并放通trust到trust和Untrust到trust的目的地址为OA服务器、目的端口为8081端口的安全策略。
[H3C]security-policy ip
[H3C-security-policy-ip]rule 10 name test
[H3C-security-policy-ip-10-test]action pass
[H3C-security-policy-ip-10-test]source-zone Untrust
[H3C-security-policy-ip-10-test]destination-zone Trust
[H3C-security-policy-ip-10-test]destination-ip OA服务器
[H3C-security-policy-ip-10-test]service 8081端口
[H3C-security-policy-ip-10-test]quit
[H3C-security-policy-ip]rule 20 name test
[H3C-security-policy-ip-20-test]action pass
[H3C-security-policy-ip-10-test]source-zone Trust
[H3C-security-policy-ip-10-test]destination-zone Trust
[H3C-security-policy-ip-10-test]quit
[H3C-security-policy-ip]quit
3.3 保存配置
[H3C]save force

感谢，这个版本怎么和以前的配置不一样了，反而感觉很麻烦
安全策略有两套，选择其中一种就可以
