如何允许外网用户Telnet至PIX的outside? 补充一下 Licensed Features: VPN-DES: Enabled VPN-3DES: Disabled
用SSH就可以。 telnet不可以!
对inside 倒dmz的访问,需要做nat配置,对于dmz到inside的访问,需
要做static 与access-list的配置。

是的,可以将针对这些主机的限制策略放在acl的最上端,应用在
inside口的in的方向上。
你可以用支持时间的acl来做,也可以用tacacs来验证用户,定义

pix上启用了DHCP,不允许内网自动获取只允许DMZ自动获如何做,谢谢
各位!

pix7.0 如何在routed 和 transparent 两种方式中切换? 我的pix 515e 升级到pix7.01 我想使用 transparent 模式, 请大家 指教如何做了? firewall transparent no firewall transparent
在515E中配置DHCP网关的命令是什么 dhcpd enable inside
pix能不能实现dmz和inside透明模式呢?
有客户想把服务器搬到dmz区,但是服务器地址不变,这样除了透明模
式我还想不到其他办法,inside和outside的透明模式我知道,但是
inside和dmz的透明模式怎么办?
地址必须改变。透明桥模式下是没有DMZ概念的。
地址不变也可以.做地址映射的时候翻译相同的地址就行了.
但是想搬到dmz区的机器和inside区的机器是同一网段的
服务器和用户都是用一网段的,不改变地址怎么搞?
如何配置PIX透明模式?
首先,需要升级pix os到7.0.1 直接输入firewall transparent 命令就可以让PIX工作在透明模式下面
。 工作在透明模式下时,pix相当于一条网线,故障切换由其它的三层设
备完成。
做防火墙的策略一般多是和端口对应的,外网在透明模式时怎样访问内
网HTTI.HTTPS.PPTP,TCP/UDP-5060/1270
有一点,透明模式下必须设置管理地址才会通
有所变化,以前用PIX515双机作failover,pix os版本
好像是6.3就不支持透明模式.看来透明模式的应用还是挺多的,可
以做网络分区之间的安全隔离,最重要的是可以让动态路由协议穿过.
如何看用命令看这两台PIX支持的最大连接数(不是使用中的最大连接
数,而是license所限制的最大连接数)
show ver. 为什么ping不通515E的outside地址? PIX的版本是6.3(4),设置了515E的outside地址和inside地址后,用网
线将笔记本和515E的outside端口联起来,本本的地址和outside地址在
一个网段内,但总是ping不通outside地址,但同样的配置在6.2版本的
515E上使用时是没有问题的,好奇怪啊??

对了,是使用cisco system VPN Client 4.01登录的,家里adsl可以连上VPN,但是不能访问,DDN就可以
其实,不光是PIX问题,我用2620做的和你的也一样,用一般的ADSL是不行的,但如果是用带路由功能ADSL就可以。
isakmp nat-traversal 120 还有客户端NAT打开,估计是NAT穿透的问题吧。
