Your samples only showed port 2036/tcp on a very low frequency. Is this 
representative for a longer period? What is the percentage of port 80/tcp 
packets?

Unlikely, if it only targets a single ip address which does not respond. Http 
might be used as destination port for such packets are likely to go through 
firewalls.

If you are interested in furhter investigation, you could run netcat on the 
attacked host to see if connection establishment goes on and if there arrives 
any data.
