Cisco ASA 5505防火墙地址映射问题
解决前些天帮朋友配置一台Cisco ASA5505防火墙, 映射总是不成功. 在网上也看到很多朋友遇到了这种问题,都在寻问这个解决方法.有人已经将问题解决了,但没给出解决方案. 也许这并不是一个很复杂的难题,但我希望通过博客能帮助朋友们及时得到这个小问题的处理.
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:

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: static (inside,outside) 221.221.147.195 192.168.0.10 tcp 8089 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.

1.IP地址配置
#int vlan1
#>nameif outside
#security-level 0
#ip address 172.16.1.1 255.255.0.0.
#end
#int vlan 2
#nameif insiede
#security-levlel 100
#ip address 192.168.1.1 255.255.255.0
#end
2.把端口指定到相应VLAN中
#int Eth0/0
#switchport access vlan 1
end
#int Eth0/1
switchport access vlan 2
end
#exit
3.配置Http.telnet和ssh管理
#username xxx password xxxxxx encrypted privilege 15
#aaa authentication enable console LOCAL
#aaa authentication telnet console LOCAL
#aaa authentication http console LOCAL
#aaa authentication ssh console LOCAL
#aaa autoentication command LOCAL
#http server enable
#http 192.168.1.0 255.255.255.0 inside
#telnet 192.168.1.0 255.255.255.0 inside
#ssh 192.168.1.0 255.255.255.0 inside
#crypto key generate rsa(打开SSH服务)
4.VPN配置
VPN配置可在ASDM模式下配置,具体配置略
