求助:openswan问题

在我的实验中需要实现linux下的IPSEC,我决定用openswan,系统是FC6,在按照一篇《十分钟配置openswan》的文章进行安装后,用ipsec verify检验除了最后OE外全部OK,接着我开始配置,我准备实现road warrior模式,我的实验环境是:

laptop(192.168.0.138)---PC(192.168.0.136)---(192.168.0.137)虚拟机1(192.168.2.1)---(192.168.2.6)虚拟机2  


   上述实验环境中,笔记本和虚拟机1均为FC6且都安装了openswan,并且测试安装通过,虚拟机1和2是由PC通过vmware虚拟的,其中,虚拟机1的eth0(192.168.0.137)是桥接在vmnet0上,而eth1(192.168.2.1)通过自定义的vmnet2和虚拟机2相连。
在laptop上ping 192.168.0.136, 192.168.0.137能ping 通,
而在虚拟机1上ping 192.168.0.136, 192.168.0.138能ping通,ping 192.168.2.6都ping通
在虚拟机2上ping 192.168.2.1能ping通,ping 192.168.0.137能ping通。
laptop(@left)上的ipsec.conf是:
version 2.0 # conforms to second version of ipsec.conf specification
config setup
   interfaces=%defaultroute
        nat_traversal=yes
   nhelpers=0
conn %default
     authby=rsasig
     compress=yes
include /etc/ipsec.d/examples/no_oe.conf
conn road
     left=192.168.0.138
     leftnexthop=@defaultroute
     [EMAIL="leftid=@left"]leftid=@left[/EMAIL]
    leftrsasigkey=xxxx     
     right=192.168.0.137
     rightsubnet=192.168.2.0/24
     [EMAIL="rightid=@right"]rightid=@right[/EMAIL]
     rightrsasigkey=xxxx
     auto=add

虚拟机1(@right)上的ipsec.conf文件是:
version 2.0 # conforms to second version of ipsec.conf specification
config setup
  interfaces=%defaultroute
        nat_traversal=yes
  nhelpers=0
conn %default
     authby=rsasig
     compress=yes
include /etc/ipsec.d/examples/no_oe.conf
conn road
     left=192.168.0.137     
    [EMAIL="leftid=@right"]leftid=@right[/EMAIL]
    leftsubnet=192.168.2.0/24
    leftrsasigkey=xxxx  
   
    rightnexthop=@defaultroute
     right=192.168.0.138
     [EMAIL="rightid=@left"]rightid=@left[/EMAIL]
     rightrsasigkey=xxxx
     auto=add

配置好之后,我在laptop端启用ipsec:ipsec auto --up road出错:提示:021 no connection named "road"
然后我将laptop端ipsec.conf配置中的红色字段[EMAIL="leftnexthop=@defaultroute"]leftnexthop=@defaultroute[/EMAIL] 改为leftnexthop=192.168.0.137 后,再启用ipsec:
#ipsec auto --up road
此时不再显示021错误,显示:
     STATE_MAIN_I1:initiate
      STATE_MAIN_I1:retransmission;will wait 20s for response
      STATE_MAIN_I1:retransmission;will wait 40s for response
      .
      .
      .
 还是不成功,到底是何原因,百思不得其解,寻求各位高手帮助,不甚感激!
