Detected TCP SYN packets attack Since Firmware update to for ER8411 (1.2.0) and ER6505 (2.2.3)
Hello,
yesterday we have update all our switches and routers. Since the update we get every 10 minutes the message with:
Detected TCP SYN packets attack and dropped 138 packets.
Update has been done at 00:30 CET therefore since this time we have get a lot of messages. The problem is that no more information is given this means we can not understand ist this a local device or an attack from outside. Is there any possible way to find the issue, device etc. which is responsible for this attacks?
Many thanks in advanced!
