Hello everybody. I am trying to raise a VPN betweeen Fw1 v4.0 on NT an d PIX 515 V5.12 thru ISAKMP. The fault is in the negociation between firewalls with this message after they shared the keys: FW1 : Isakmp log: Sent notification: Invalid id information PIX : return status is IKMP_NO_ERR_NO_TRANS Its seeems a problems of interoperability. Someone have any ideas.
