  The AOL stack, from last I looked into it, will not work with
CheckPoint's Secure Remote either. After I found out, we had to
bypass AOL when creating an ecrypted tunnel vpn. Apparently, they
do something with the TCP/IP stack, I think they implement their own,
much like the problems we had with some versions of winsock.
 I thought some vendors were working around that, but not looked
into much lately.
