Excessive watchguard traffic

Posted on 2014-08-13

We have a Watchguard XTM330 device. The logs are showing a fairly constant stream of denied traffic from external IP addresses to our public IP.
Can anyone help with interpreting these and should they be of concern.
I have attached a screen clip of the traffic monitor window. Sorry it is not the clearest.
I have also attached the text entries.

    Can you attach logs in compressed text format?

    It looks like common distributed portscan. Watchguard (or even human operator) cannot identify this type of access and log a short line for all related packets.
    Just check your rules that nohing unnecessary shows up from internet to make sure you are safe.
