Ipsec配置与openswan

Question

我尝试用openswan作为客户端在服务器上配置Ipsec。

但是接收错误是可能的，这是唯一的错误。

我在配置上写错了什么？

谢谢你的回答。

问题是在ESXi桥。(我们这边的Virt服务器位于带有外部IP的ESXI主机上)，但是在nake硬件(相同的SL6-RHEL 6)上工作，ipsec工作得很好。

config on our side : 


conn f-net    
type=tunnel    
keyexchange=ike    
authby=secret    
auth=esp    
esp=aes-sha1    
keyingtries=3    
pfs=no    
ike=aes256-sha1-modp1536    ##   also works  without it    
left=4***    
leftsubnet=****    
leftid=4***    
leftnexthop=%defaultroute      # correct in many situations    
right=8***           # Remote vitals    
rightsubnet=****    
rightid=8***    
rightnexthop=%defaultroute     # correct in many situations    
auto=add
