My logs on several of my WAN routers are full of the following messages -
730: IKE message from xx.xx.xx.xx has no SA and is not an initialization offer
728: Processing of Main mode failed with peer at xx.xx.xx.xx
1192: Processing of Informational mode failed with peer at xx.xx.xx.xx
These routers do not have IPSEC feature on them, and thus do not provide any vpn services.
How can I stop this from happening? Is there another way becides blocking these IP's in an access list?
