IPSEC operation in FC3

[Kye-Sang Lee]

I am trying to reach a WIndows XP machine by using the IPSEC in FC3. 

I believe almost all configurations were done through the use of 
the IPSEC tab in the system-config-network command. Looks like 
the IKE protocol is working, but they cannot communicate.I see 
the messages 'Negotiating IPSEC failed' , when I ping the FC3 
machine from XP. 
 
When I ping the XP from FC3, I get the message 'resource 
unavailble temporarily'. Through the tcpdump, I notice that 6 
ISAKMP messages are transmitted from the FC3 to the XP. 
 
The information above might be not enough to give you a figure. 
However, I would feel great to share any idea on this point.

Best Regards,
