如何答应外网用户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。
PIX 515E连接ADSL 路由MODEM！
想知道E0口上怎么配置与开启路由的MODEM的连接。让内网所有用户可以都通过这个MODEM上网。
ADSL MODEM IP:192.168.1.1
pixfirwall(config)#vpdn group <组名> request dialout pppoe
pixfirwall(config)#vpdn group <组名> ppp auth PAP/CHAP/MSCHAP
pixfirwall(config)#vpdn group <组名> localname <拨号的用户名>
pixfirwall(config)#vpdn username <用户名> passWord <密码>
pixfirwall(config)#ip add <接口名称－随便定义> pppoe
我想通过在pix 515e 上进行设置使某些内网用户只能上一个特定的网站
当前配置如下:

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downloaded acl
请教pix515 acl 如何屏蔽一个网段？
deny ip host 61.129.64.* any
61.129.64.*这样的网段该咋样屏蔽？

pix上启用了DHCP，不答应内网自动获取只答应DMZ自动获如何做。
dhcpd address 192.118.0.5-192.118.0.254 dmz
dhcpd enable dmz
dhcpd dns 219.141.136.10 218.247.141.68
这样就可以了！
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治理地址才会通
有所变化，以前用ＰＩＸ５１５双机作ｆａｉｌｏｖｅｒ，pix os版本似乎是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）

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，好希奇啊？？

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，但假如是用带路由功能ADSL就可以。

还有客户端NAT打开，估计是NAT穿透的问题吧。

pix515的问题
具体现象是，DMZ和inside各接一台单机，DMZ的单机能用上网，其他不能，inside的机器什么都干不了。单机保证无问题。请各位帮忙看看配置吧。 outside的地址和global的地址不同，有影响么？（没有空闲的连续地址了,只能用两个不同地址表示一下）
