快速清空PIX/ASA的配置的命令使用clear config all可以快速清空PIX和ASA的所有配置,不需要重新启动。

ASA与PIX?#37027;?#21035;

No Comments CISCO , ,

很多年来,Cisco PIX一直都是Cisco确定的防火墙。但是在2005年5月,Cisco推出了一个新的产品——适应性安全产品(ASA,Adaptive Security Appliance)。不过,PIX还依旧可用。我已听到很多人在多次询问这两个产品线之间的差异到底是什么。让我们来看一看。

Cisco PIX是什么?

Cisco PIX是一种专用的?#24067;?#38450;火墙。所有版本的Cisco PIX都有500系列的产品号码。最常见的家用和小型网络用产品是PIX 501;而许多中型企业则使用PIX 515作为企业防火墙。

PIX防火墙使用PIX操作系统。虽然PIX操作系统和Cisco IOS看起来非常的接近,但是对那些非常熟悉IOS的用户来说,?#25925;?#26377;足够的差异性弄得他们头昏脑胀。

PIX系列的防火墙使用PDM(PIX设备管理器,PIX Device Manager)作为图形接口。该图形界面系统是一个通过网页浏览器下载的Java程序。

一般情况下,一台PIX防火墙有个外向接口,用来连到一台Internet路由器中,这台路由器再连到Internet上。同时,PIX也有一个内向接口,用来连到一台局域网交换机上,该交换机连入内部网络。

Cisco ASA是什么?

而ASA是Cisco系列中全新的防火墙和反恶意软件安全用具。(不要把这个产品和用于静态数据包过滤的PIX搞混了)

ASA系列产品都是5500系?#23567;?#20225;业版包括4种:Firewall,IPS,Anti-X,以及VPN.而对小型和中型公司来说,还有商业版本。

------中间广告---------

总体来说,Cisco一共有5种型号。所有型号均使用ASA 7.2.2版本的软件,接口也非常近似Cisco PIX.Cisco PIX和ASA在性能方面有很大的差异,但是,即?#25925;茿SA最低的型号,其所提供的性能也比基础的PIX高得多。

和PIX类似,ASA也提供诸如入侵防护系?#24120;↖PS,intrusion prevention system),以及VPN集中器。实际上,ASA可以取代三种独立设备——Cisco PIX防火墙,Cisco VPN 3000系列集中器,以及Cisco IPS 4000系列传感器。

现在,我们已经看过了两种安全工具各自的基本情况,下面我们来看看他们互相比较的结果。

PIX对ASA

虽然PIX是一款非常优秀的防火墙,但是安全方面?#37027;?#20917;却在日新月异。仅仅使用一台静态数据包过滤防火墙来对你的网络进行保护?#35328;对?#19981;够了。对网络而言,新的威胁层出不穷——包括病毒,蠕虫,多余软件(比如P2P软件,游戏,即时通讯软件),网络欺诈,以及应用程序层面的攻击等?#21462;?

如果一台设备可以应付多种威胁,我们?#32479;?#20854;提供了“anti-X”能力,或者说它提供了“多重威胁(multi-threat)”防护。但PIX恰恰无法提供这种层次的防护。

绝大多数公司不希望采用安装一台PIX进行静态防火墙过滤,同时再使用一些其他的工具来防护其他威胁的办法。他们更希望采用一台“集所有功能于一身”的设备——或是采用一台UTM(统一威胁管理)设备。

而ASA恰好针对这些不同类型的攻击提供了防护。它甚至比一台UTM设备更厉害——不过,要成为一台真正的UTM,它还需要装一个CSC-SSM模块(CSC-SSM,内容安全以及控制安全服务,Content Security and Control Security Service)才?#23567;?#35813;模块在ASA中提供anti-X功能。如果没有CSC-SSM,那ASA的功能看起来会更像一台PIX.

那么,到底哪一个才适合你的企业呢?#31354;?#22914;我们通常所?#26723;模?#36825;要看你企?#26723;?#38656;求而定。不过,我?#25925;?#20542;向于优先选择ASA,而后才是PIX.首先,一台ASA的价格要比同样功能的PIX要低。除去成本的原因不谈,至少从逻辑上来说,选择ASA就意味着选择了更新更好的技术。

对于那些已经在使用Cisco PIX的人来说,Cisco已经提供了一个迁移指?#24076;?#20197;解决如何从Cisco PIX迁移到ASA上的问题。就我观点而言,我觉得这起码预示了一点,就是Cisco终止PIX的日子正离我们越来越近。虽然Cisco公?#26087;形?#26126;确宣布这一点,但是我认为这只是一个时间问题罢了。

Cisco PIX防火墙实现双出口

No Comments CISCO , ,

Cisco PIX防火墙实现双出口

一、用户需求 用户有一台Cisco PIX 515E防火墙,一个网通的出口,一个电信的出口。现在要实现默认都往电信线路出去,而访问网通的网站时使用网通的线路出去。
二、实现要点
1、首先要收集网通的IP网段(这个可以在网络上搜索,或者电信的朋友要一份);
2、在路由方面,由于Cisco PIX是偏向于防火墙的功能,因此PIX在路由方面是比较弱的无法通过策?#26376;?#30001;来实现,在此我使用了默认路由往设成电信的网关,同时添加网通IP网段的静态路由。这样实现了两个出口路由的走向。
3、在NAT方面,要配置两条NAT,其中一条是通往网通的转换成网通的出口IP,另一条是通往电信的转换成电信的出口IP,这个NAT应该是网通的NAT要配置在电信NAT前面,否则将无法实现。
三、Cisco PIX双出口配置
3.1 环境描述
nameif ethernet0 outside security0
nameif ethernet1 inside security100
nameif ethernet5 teloutside security0
ip address outside 224.254.14.164 255.255.255.0
ip address inside 192.168.0.1 255.255.255.0
ip address teloutside 202.99.114.91 255.255.255.128
#备注:outside为网通线路出口;teloutside为电信线路出口;inside为内网接口;

B、定义Access-list 为作NAT准备
access-list 101 permit ip 192.168.0.0 object-group wtnetwork
#内部网络到网通IP网段的Access-list
access-list 104 permit ip 192.168.0.0 255.255.255.0 any
#内部网络到任何IP的Access-list
C、NAT配置
global (outside) 1 interface
#定义NAT ID 1为网通的出口ip
global (teloutside) 4 interface
#定义NAT ID 4为电信的出口ip
nat (inside) 1 access-list 101
#定义符合access-list 101(就是内部到网通IP网段)就转换成NAT ID 1的IP(网通的出口)
nat (inside) 5 access-list 105
#定义符合access-list 101(就是内部到网通IP网段)就转换成NAT ID 1的IP(网通的出口)
注意:nat (inside) 1 access-list 101一定要在nat (inside) 5 access-list 105前面。
D、Route路由配置
#####添加默认路由往电信的网关出去################
route teloutside 0.0.0.0 0.0.0.0 202.99.114.126 1
##################################################

四、实现效果
目前国内的骨干网分为南、北两张网。?#31995;?#20449;北网通,不通运营商之间的通讯都需要到骨干进行数据交换,因此网通的用户访问电信网站很慢而电信用户访问方位网通网站也很慢,因此对大型网络设置双出口可以使不同运营商之间网络访问速度得到改善,本文档是在这一背景下产生的需求。
