When initiating the Quick Mode negotiation from the cluster side, packets may be routed via a different interface than the one through which the VPN client connections came (e.g VPN clientВ connects via DMZ network to external cluster address, but theВ Quick Mode negotiation from cluster goes out with the DMZ cluster address, as the source address).

Outgoing and incoming packets via different interface.

This option will maintain the NAT mapping of the client IKE session in the NAT device.

To fix the problem, check the 'Enable back connections' option in the Global Properties / Remote Access menu and update the site in the VPN clientВ station.

In this case, it is not possible to route theВ Quick Mode packet to the client and the packets will be discarded. If the client address is NATed on the way to the cluster, the NAT mapping may already have expired in the NAT device, when the cluster initiates the Quick Mode negotiation.

NAT mapping expired in NAT device between the client and cluster.

Checking the option 'Accept outgoing packets originating from Gateway' will let the IKE negotiation go through in this situation. With NATed connections, the source port in the client IKE session may vary, and when the cluster side initiates the IKE negotiation to the client port, the session is not matched with the implied IKE rule. If the clients come over a NATed connection, check also the option 'Accept outgoing packets originating from Gateway' in the Security Gateway Global Properties menu. Check that the Implied Rules allow outgoing IKE connections.

Rule base prevents outgoing connections from cluster.

If packets get dropped in an IPSO cluster, even though the VPN client connections have been properly established and are active, you should verify that there is nothing in the cluster configuration that blocks the outgoing Quick Mode negotiations.ДЇailures with the Quick Mode negotiations have been observed in the following situations: In this case, t he logs show packets being dropped with the above error message. If the SA negotiation initiated from the cluster side fails for some reason, a situation can arise where part of the connections to the encryption domain work properly, but some of the connections fail.

Whether the cluster initiates anyВ Quick Mode SA, and the time when it happens, depends on the client traffic, and how the client sessions are allocated between the cluster members. The Quick Mode SA from the cluster side is not necessarily established immediately, or automatically when the VPN clientВ station connects. The SA is initiated when a return packet is handled by another cluster member than the one that handled the initial client IKE connection. In the IPSO cluster and Check Point cluster environment, there can be a Quick Mode SA initiated also from the cluster side to the VPN client station and not just from the client side to the cluster.Д®ven though there is already an active IPSec SA, established by the client, theВ Check Point cluster sometimes wants to establish its own, corresponding IPSec SA.
