使用pix 机房互联

分类： 系统运维

2016-01-15 21:08:56


  1. 在国内的IT环境中，老板对于IT预算还是有限的，老板要求花最少的钱把事情办好，当然在互联网企业或者IDC机房以网络为核心的企业来讲，
  2. 网络架构的好坏是其命脉，许多服务架构集群都需要建立在网络的基础上。
  3. 最近机房互联做的一个项目，之前的设备实在是不能满足需求了，老板当然不愿意出钱，花上万的设备去给你搭建。怎么办呢，在总部机房有一台很老的PIX设备，事实上这台设备问世至今跟我的年龄相差无几，但却稳健的运行了近三个月时间，没有任何故障，当初在淘宝逛的时候看到PIX设备只有不到两百块。
  4. 跟BOSS商量直接买了4台，用于机房搭建。另外购一台cisco 3550的三层交换机，几百块就搞定。现稳定运行，大概需求(让内网可以NAT上网，机房VPN互通，端口映射)
  1. cisco 防火墙容易出现的问题
  2. 问题描述：
  3. 当调试思科VPN的时候，尤其是远程拨入VPN的调试，你会发现，当调试路由器的时候，客户端拨入可以直接访问路由器的内口地址，但是当设备是思科的安全设备（PIX,ASA）的时候，你去尝试一下，你会发现在访问INSIDE接口的时候，结果是不通的。
  4.  
  5. 解决办法：
  6. 因为思科的安全设备安全级别高一些，所以他默认会对从低安全级别的访问做一定的限制，例如设备的管理权限；大家都知道防火墙从外网是不能TELNET到本机上的，相比SSH本身安全的多的多，但是INSIDE可以TELNET，默认内部是最高安全级别，所以TELNET当然对本身不会造成多大破坏，但是思科的人性化体现的很淋漓尽致，对于远程客户端通过VPN客户端拨入的用户（可能会出现帐户泄露等因素），防火墙默认是不允许这些客户访问他本身的，这样就更增强了自身的安全性，个人觉得非常好！！！！
  7. 解决此办法很容易
  8. 在全局模式下 输入
  9. management-access inside 这条命令就可以了
配置pix ssh  （非AAA Authentication方式）
domain-name zsq.cn 
ca gen rsa key 1024 
ssh 0.0.0.0 0.0.0.0 outside
ssh timeout 60
passwd Tcs6688.cn@pix
ca save all 
write mem
需要注意的是write mem并不能保存rsa key的配置，必须使用ca save all来保存
默认用户为pix

备注：
这个机房连接的三层交换，vlan段是15段的，故VPN感兴趣流是15段，这里就不贴配置了，其实就是接口跟本PIX接口互联下。然后设置VLAN
