I'm trying to open my checkpoint firewall to allow connections from one
PC of my network to a remote network using The Greenbow VPN client, but
it is not working.

At the remote VPN log I can see this:


[==== IKE PHASE 1(from XXX.XXX.XXX.XXX) START (responder) ====]
**** RECEIVED  FIRST MESSAGE OF AGGR MODE ****

<POLICY: HSTSIfCB> PAYLOADS: SA,PROP,TRANS,KE,NONCE,ID,HASH
**** SENT OUT SECOND MESSAGE OF AGGR MODE ****
**** RECEIVED IKE NOTIFY PAYLOAD(INVALID_COOKIE) ****

What is this message "RECEIVED IKE NOTIFY PAYLOAD(INVALID_COOKIE)" ?

Any idea?

Thank you.
