两台linux机器配置分别为：
eth0 192.168.0.235，eth1 192.168.1.235，gateway 192.168.0.11；
eth0 192.168.2.235，eth1 192.168.1.236，gateway 192.168.2.200。

linux版本为2.6.19，openswan版本为2.4.6，protostack为KLIPS。


ipsec.conf分别设置为：
version 2.0     # conforms to second version of ipsec.conf specification
# basic configuration
config setup
        nat_traversal=yes
        nhelpers=0
        protostack=klips
include no_oe.conf
conn liu
        left=192.168.1.235
        leftsubnet=192.168.0.0/24
        [email=leftid=@serein]leftid=@serein[/email]
        leftnexthop=192.168.0.11

        rightnexthop=192.168.2.200
        auto=add
和
version 2.0     # conforms to second version of ipsec.conf specification
# basic configuration
config setup
        nat_traversal=yes
        nhelpers=0
        protostack=klips
include no_oe.conf

conn liu
        left=192.168.1.236

        rightnexthop=192.168.0.11
        auto=add

ipsec setup start两台机器都是OK的。但是ipsec auto --up liu出错，出错信息如下：
pluto[1827]: "liu": We cannot identify ourselves with either end of this connection.
022 "liu": We cannot identify ourselves with either end of this connection.

找了很长时间，没有发现错在哪儿，各位老大帮忙看看，问题出在什么地方，谢谢！
