Hi. I have two separate ipsec tunnels from 4.9 boxes and both are generating this message i /var/log/messages once every hour or two Jul 2 08:14:54 <hostname> isakmpd[28247]: message_recv: invalid cookie(s) 576<scrambled>03c2 Jul 2 08:14:54 <hostname> isakmpd[28247]: dropped message from x.x.x.x port 500 due to notification type INVALID_COOKIE
The tunnels works perfect but I still wounder why I got this message. This is my ipsec.conf on host x ike esp transport from x.x.x.x to y.y.y.y psk <scrambled> and on host y ike esp transport from y.y.y.y to x.x.x.x psk <scrambled> Any idea? Best regards rancor
