I found a couple things.  First check out this site: http://sisyphus.iocaine.com/pipermail/vpn/2004-January/004579.html.  It suggests using IPsec over TCP, instead of UDP.  The other thing I found was an issue with Microsoft XP.  I'm not sure if this is what you are using or not but you may want to check out this site: http://support.microsoft.com/?kbid=838207.  It says by upgrading to SP2 you may be able to fix this issue.
