IPSec & compression

[David Passamonte]

To support compression the VPN gateway, in this case Check Point, will have
to support compression as well. As I recall Check Point didn't support
IPComp(RFC 2393) or Deflate in 4.1, but maybe they rolled it into 5.0. The
SafeNet client supports Deflate in SoftPK 5.0 and they do interoperate with
Check Point. But then again, your kind of dependant on the gateway
supporting the algorithm.  Check out the Check Point 5.0 enhancements if you
haven't yet. Chances are if they added this support to the gateway they put
it in the client as well.

I thought that a lot of VPN clients built compression
in?  I don't know about SecuRemote in particular, but I
do know that a lot of the other products I've reviewed
discuss compression algorithms in their technical
documentation.  It has to be done before the encryption
to be effective.
