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,
