Re: Application Intelligent vs ALG

["Shimon Silberschlag" <shimons () bll co il>]

It is my understanding that CP is different from an ALG because with
an ALG, the ALG rewrites the packet to the destination, while with
Checkpoint Application Intelligence, they only check if its "safe" to
pass to the destination.

If its better or not, remains to be seen.
