What is Forwarding Layer?
When a member forwards a packet to another member through the forwarding layer once it has been inspected locally, what special item informs the peer member that the packet has already been inspected?
How and why does a member forward a package to a peer member through the forwarding layer?
Packets originated by cluster members can pose problems in the following situations: - New High Availability mode. The connection is opened from the stand-by member. All packets from the external host are handled by the active member, instead of the original gateway. - Load Sharing mode. The decision function has selected another member to handle this connection. This can happen since packets directed at a cluster IP are distributed among cluster members as with any other connection. What is the solution to ensure that a packet originated by a security gateway is forwarded to that gateway?
