a lot of spoofed traffic for port 8, does anybody recon this?

[Mikael Fors <mf () MORADATORER SE>]

Last 24 hours I've been receiving a lot of strange packets on my public interface. Log has been sanitized.

These packets started trickling here about 48 hours ago, and I have no clue what it can be. What resides on port 8 and 
why ICMP??? All of these packets arrive on the public interface, and contains private networks, mostly 192.168.x.x 
networks, but also 172.x.x.x networks show up.
