我也遇到这样的问题，中心是思科2611XM路由，虚拟拨号通过电信光纤上互联网，电信给用户帐号绑定公网地址，只要用户帐号拨到电信，就分配同一个公网IP地址，相当是给了一个固定的地址，分点是ADSLMODEM加思科1721路由，虚拟拨号PPPOE到电信，分配不固定的地址，每次拨上地址都不同。中心与分点建立VPN，设置后，双方上网都可以，但就是建立不了VPN，在分点1721上打开DEBUG，根本没有信息。不知为何，这种方式是否可行，如可行，该如何配置？

关于四台Cisco防火墙实现VPN网络的实施
其实四台Cisco防火墙的VPN同两台防火墙做VPN没什么大的区别，只是一定要注意路由的配置（我就是在这上面花了很长的时间，不是多写就是少写了，多少都是不会通的）；在四台Cisco pix做VPN中，有两种方式，一种是采用一个中心的方式，另一种就是分散式的（我自己起的名字J），前者，也就是说以一个PIX点为中心，其它的机器都连到本机上，在通过本机做路由；后者，则是在每一个路由上都要写出到另外三台的加密方式（听来就很麻烦），这里我采用的就是第一种类型（不是我偷懒，而是客户要求，谁让客户是上帝了呢！）；
以下，是施工图以及四个Cisco pix的详细配置：
详细配置如下：

在以上的配置中，主要是中心点的路由，要注意，在配置过程开始时，sh isakmp sa 发现链路以建立，可是就是Ping不通，发现是因为没有针对于所在地的路由，还有就是当打开debug命令监控时，debug crypto isakmp ; debug crypto ipsec ;时，在内网的机器执行ping命令后，没有任何反映，后发现缺少命令激活扩展列表，具体命令：nat (inside) 0 access-list 101,
在就是我在pix3时内部多加了两条路由，静态的到中心的路由，在pix3以内怎么也Ping不出去，后来去掉以后发现通过。看来多写也是不行的。从总的来说，两台pix做vpn同多台机器做vpn没什么什么大的区别，主要是多写几条peer，也就是crypto map tohyjt 20 set peer 192.168.0.2（中间的名字 tohyjt这个没什么实际的规定，想写什么就写什么，但是最好是一致）和isakmp key cisco address ；在就是前面所提的路由（在中心点的配置中可以看到，在这里我隐去了真正的ip，主要是为客户的安全考虑，而已一个私有的IP网段来设定；），
不知道这对大家是否有帮助，希望有问题大家一起来学习。
--------------------------------------------------------------------------------------
继续深入讨论下去。
balance可能误解了我的意思，现在的难题是hub如何知道每一个spoke和相应的lan地址对应起来。
举个很简单hub-spoke的例子：
192.168.2/24--b-2.2.2.2---------------------
1.1.1.1-A-192.168.1/24
192.168.3/24--C-3.3.3.3---------------------
在B和C两个spoke的合法地址都固定的情况下，hub端应该至少会存在哪下的配置：
crypto map mymap 10 ipsec-isakmp
set peer 2.2.2.2
match address 102
crypto map mymap 11 ipsec-isakmp
set peer 3.3.3.3
match address 103
access-list 102 permit ip 192.168.1.0 0.0.0.255 192.168.2.0 0.0.0.255
access-list 103 permit ip 192.168.2.0 0.0.0.255 192.168.3.0 0.0.0.255
从这里可以看出，实际上每一段lan地址和spoke的关联，是由acl手工指定的，并通过和set peer的关联联系到相应的spoke上面。
那么，当spoke 的地址为动态地址时，应该如何才能将lan绑定到相应的spoke上呢？？？pepeng说有可能在协商SA的时候交换spoke后端的lan的信息，我觉得这种可能性不大，至少在cisco的ipsec实现中可能性是相当小的(真能这样的话，ipsec的配置可以说是大大的简化了。)
所以，我的结论仍然是：在目前的实现中，hub-spoke的lan2lan的ipsec，需要每一个站点都具备固定的合法IP地址。事实证明我的结论是错误的。
-----------------------------------------------------------------------------
再补充一下，实际环境和实验环境中是有很大的区别的。
1、不管是hub端还是spoke端，从路由的层面上来说，都是一条缺省路由到ISP的第一跳路由器。
2、实际环境中，spoke端的地址根本就是全动态的，没办法配置peer，只能按照access vpn的方式进行配置，或使用set peer 0.0.0.0匹配所有的spoke。这种情况下，有一个最关键的问题就是hub如何知道哪一个LAN在哪一个spoke的后面？？？？
-------------------------------------------------------------------------------
Cisco 现在有个称为 DMVPN (dynamic multipoint VPN) 的DD，可以实现动态IP的spoke之间的通讯了，上面链接有sample
Dynamic Multipoint VPN: Generic Route Encapsulation (GRE) provides multiprotocol routing, dynamic routing updates for site-to-site networks, and Multicast access. Dynamic Multipoint VPN (DMVPN) extends this in terms of providing the same GRE benefits to dynamic users (ie: access to IP/TV) and also provides a "Full-Mesh" site-to-site connectivity. DMVPN can achieve this because it is used in combination with Next Hop Resolution Protocol (NHRP) and Multipoint GRE.
