H3C SecPath 防火墙设置之端口映射

2012-12-25

登陆系统后: 1.显示防火墙当前生效配置参数。 H3Cdisplay current-configuration 找到如下信息:# interface Ethernet0/0ip address 172.16.1.1 255.255.255.0nat outbound 2000 nat server proto...

登陆系统后: 1.显示防火墙当前生效配置参数。 H3Cdisplay current-
configuration 找到如下信息:
# interface Ethernet0/0
ip address 172.16.1.1 255.255.255.0
nat outbound 2000 nat server protocol tcp
global 172.16.1.1 www inside 192.168.1.254 www
登陆系统后:
1.显示防火墙当前生效配置参数。
<H3C>display current-configuration
找到如下信息:
#
interface Ethernet0/0
ip address 172.16.1.1 255.255.255.0
nat outbound 2000
nat server protocol tcp global 172.16.1.1 www inside 192.168.1.254 www
nat server protocol tcp global 172.16.1.1 22 inside 192.168.1.254 22
2.进入系统视图
<H3C>system-view
[H3C]
3.进入网卡0
[H3C]interface ethernet0/0
[H3C-Ethernet0/0]
4.运行nat 命令添加FTP端口映射。
[H3C-Ethernet0/0] nat server protocol tcp global 172.16.1.1 ftp inside
192.168.1.254 ftp
5.查看防火墙当前生效配置参数。
<H3C>display current-configuration
找到如下信息:
interface Ethernet0/0
ip address 172.16.1.1 255.255.255.0
nat outbound 2000
nat server protocol tcp global 172.16.1.1 www inside 192.168.1.254 www
nat server protocol tcp global 172.16.1.1 22 inside 192.168.1.254 22
nat server protocol tcp global 172.16.1.1 ftp inside 192.168.1.254 ftp
6.测试FTP端口是否映射成功。
C:\Documents and Settings\aran>ftp 5X.21X.24X.24X
Connected to 5X.21X.24X.24X.

一,用固定的公网ip做映射命令
System
int dialer 0
[Quidway-Ethernet3/0] nat server protocol tcp global 200.200.200.1 外网
端口inside 192.168.1.254 内网端口
[Quidway-Ethernet3/0] nat server protocol tcp global 200.200.200.1 外网
端口 inside 192.168.1.254 内网端口
【提示】
1、global后跟公网地址,inside后跟的是私网服务器地址,www和ftp可以改为端
口号
2、内部用户不能使用公网地址来访问内部服务器,必须使用内网地址访问.,如
192.168.1.0/24网段的用户,不能访问http://200.200.200.1,而只能访问
http://192.168.1.254
二,如果没有固定ip,对于上面命令要作修改,修改如下
system
int dialer 0
nat server pro tcp global current 内网端口 inside 192.168.1.2 外网端
删除命令
在前面加上undo nat server pro tcp global current 内网端口 inside
192.168.1.2 外网端口
三,display nat all命令用来显示所有的地址转换的配置信息
【视图】
