IPSec between Windows XP/2003 and Windows 7/2008 R2

i see lot of posts how people not able ipsec working between windows xp/2003 , windows 7/2008 r2 computers, don't see solutions.

has been able working?  if so, how?

i have same exact ipsec polices applied xp , windows 7 computers.  when try access xp comptuer windows 7 computer, works fine.  when try access windows 7 computer xp computer, doesn't.  see traffic getting windows 7 computer, being dropped.  firewalls disabled , ipsec policy set "request".  default windows 2003/xp "request" security being used.  windows 7/2008 r2 computers can communicate each other without problems, xp/2003 cannot communicate each other or with windows 7/2008 computers, shows security association has been negotiated , exists using ipsec monitor tool.  if disable ipsec server or apply customized "permit all" unecrypted policy windows xp/2003 computers, can communicate normally.

there has difference between xp/2003 , 7/2008, cannot find information different , how adjust settings make them compatible.

any appreciated.

hi slindley,

 

thanks posting here.

 

could discuss how did disable firewall windows7/2008 hosts? actually, should not disable since need supporting ipsec communication.
