Is this something important?

[ramon () CIMAT MX (Ram'on Reyes Carri'on)]

Thank's for having a look at this.

I am getting the following in my router's log and don't understand much of
what it means, but the src and dst=131.107.2.255 (deleted) IP addresses
are outside of my network.

Is it spoofing, misconfiguration or something else?

The first line appears before each of the others, the last few lines look
a bit odd:

(Sorry for the length, I wasn't sure what to delete! I did prot=17 and
I have  sport=dport)
