一、ASA和PIX基础配置

1、ASA防火墙配置

1、GNS配置

因为使用的GNS3的版本可能不同,gns配置asa防火墙的步骤可能不同

在低版本的gns中直接在qemu选项里可以直接配置,参考:https://blog.51cto.com/dldxzjr/1905682

在高版本的gns中配置可以参考:https://wenku.baidu.com/view/8934accc48649b6648d7c1c708a1284ac850059c.html

2、简单的防火墙设置命令

show version
show running-config
show activation-key 查看激活秘钥
activation-key key-values 设置激活秘钥
write mem 将配置保存到非易失flash,重启或断电都不会对配置产生影响
no shutdown 使借口处于启用 show interface ip breif 提供接口的简短概要
interface 接口
nameif inside/outside/dmz
ip address ip地址 掩码
speed auto #连接速度,有10/100/1000Mbps等
duplex auto #双工模式,有Half/Full为半双工/全双工模式
#一般网卡都为Auto/Auto适配出来的情况一般为100M全双工模式 #防火墙上设置静态路由,最多可以配置3个不同的默认路由
例:
指向外部接口上的网关192.168.1.1的路由 route outside 0.0.0.0 0.0.0.0 192.168.1.1 1
可通过内部接口上的网关192.168.254.2找到网络172.21.0.0/16 route inside 172.21.0.0 255.255.0.0 192.168.254.2 1
删除则直接加一个no
show route #
show xlate
show conn

2、pix防火墙配置

安装时有一步需要激活

activation-key key

关闭重启pix防火墙:

还有一点需要注意,就是pix运行时有一个进程pemu会占用大量的cpu资源,导致很卡,可以使用BES对它进行限制:

二、PIX-NAT

1、pix配置动态NAT

基础命令举例:

show int ip b
hostname
ip address
nameif
security number show conn 显示所有的活动连接
show conn detail
show local-host
show xlate 显示翻译(xlate)槽位的内容
show xlate detail #添加acl,访问规则
1)创建标准访问列表
access-list [list-number] [permit|deny] [source-address] [wildcard mask] [log]
access-group list-number in int 接口名 #静态NAT
static [(internal_if_name, external_if_name)] global_ip local_ip[netmask network_mask][max_conns
[em_limit]] [norandomseq]
例:static (inside,outside) 13.0.1.3 192.168.1.2 将本地地址192.168.1.2转换为全局地址13.0.1.3 #static PAT
static [(real_interface, mapped_interface)] {tcp | udp} {mapped_ip | interface}
mapped_port {real_ip real_port [netmask mask] 例:dmz:172.16.1.9 outside:192.168.0.9
static (dmz,outside) tcp 192.168.0.9 ftp 172.16.1.9 ftp netmask 255.255.255.255 #动态NAT
nat (inside) 1 192.168.1.0 255.255.255.0
global (outside) 1 12.0.1.0-12.0.1.9 netmask 255.255.255.0 #PAT
nat (inside) 1 192.168.1.0 255.255.255.0
global (outside) 1 12.0.1.9 netmask 255.255.255.0 #nat 0
nat (dmz) 0 192.168.0.9 255.255.255.255
#
no global (outside) 1 12.0.1.0-12.0.1.9 netmask 255.255.255.0 route if_name ip_address netmask gateway_ip [metric] 为接口口if_name定义一条静态或缺省路由 #

R1

R1#ip route 0.0.0.0 0.0.0.0 192.168.1.1
!因为我们是用路由器R1模拟的主机,所以要么关闭路由功能,配置网关;要么添加一条路由让路由器发出的消息从192.168.1.1出去

2、static NAT
