ASA 5510 配置案例(解决端口映射问题).txt 老公如果你只能在活一天,我愿用我的生命来 延续你的生命,你要快乐的生活在提出分手的时候请不要说还爱我。Cisco ASA 5505 防火墙 端口映射问题解决

基本情况:

WAN: 221.221.147.195

Gateway: 221.221.147.200

LAN: 192.168.0.1

内网中有一台服务器,地址: 192.168.0.10

端口: 8089

故障描述: 内网可正常连接至服务器,外网无法连接.

端口映射出现问题.

解决方法: 命令行错误, 已更正并解决.

问题重点: 采用 "static (inside,outside) 221.221.147.195 192.168.0.10 tcp 8089" 映 射.

目前配置如下:

ASA Version 7.2(2) ! hostname ciscoasa enable password 8Ry2YjIyt7RRXU24 encrypted names ! interface Vlan1 nameif inside security-level 100 ip address 192.168.0.1 255.255.255.0 ! interface Vlan2 nameif outside security-level 0 ip address 221.221.147.195 255.255.255.252 ! interface Ethernet0/0 switchport access vlan 2 ! interface Ethernet0/1 ! interface Ethernet0/2 ! ! interface Ethernet0/4

------------------------------------------------------------

在 找 寻 解 决 方 案 过 程 中 , 有 朋 友 做 了 重 要 提 示 , 采 用 : static (inside,outside) int 192.168.0.10 tcp 8089 做映射,但出现警告提示:

WARNING: static redireting all traffics at outside interface; WARNING: all services terminating at outside interface are disabled.

后来将命令改成: 问题解决.

static (inside,outside) 221.221.147.195 192.168.0.10 tcp 8089

这几天又配置一个 asa5505 的防火墙 采用 static (inside,outside) 221.221.147.195 192.168.0.10 tcp 8089

不通。

后采用

static (inside,outside) tcp interface 8089 192.168.0.10 3389 netmask 255.255.255.255
