Hello,
I have a log on the router that shows a problem in the tunnel;
%CRYPTO-4-IKMP_PKT_OVERFLOW: ISAKMP message from Ip-adsress larger (-1553241989) than the UDP packet length (100)
and Cisco stated that it may indicate a DoS attack , but I don't know how to troubleshoot this problem and what is the cause ?
Kindly advice.
Thanks & BR

Could you please paste a few complete lines of this error message without any modifications? Also, please give some more background info about the network setup.
