Last time i used Wireshark, when i restricted all internet access with my firewalls there used to be 0 activity. Now a few months later this thing pops up. What is it and how do i get rid of it ? Im concerned that it's getting past my 2 firewalls.

The raknet dissector is a heuristic dissector that has no preferences to specify a port.
It could be a fluke that your traffic matches the weak heuristic test for a match.
epan/dibe ssectors/packet-raknet.c

test_raknet_heur(tvbuff_t *tvb, packet_info *pinfo _U_, proto_tree *tree _U_, void* data _U_)
    if (tvb_memeql(tvb, 1 + 8, RAKNET_OFFLINE_MESSAGE_DATA_ID, sizeof(RAKNET_OFFLINE_MESSAGE_DATA_ID)) == 0) {
        return TRUE;

Disable it (Analyze -> Enabled Protocols... -> Search: "raknet") and see if another dissector claims the packets.

306 74.725687    UDP 75  14349 → 31313 Len=33

Is this on a Windows machine? Similar question answered using sysinternals.
UDP Port 889 Broadcast (ip.ttl "Time to Live" only 1)

I turned off everything again, blocked all traffic with my firewalls, reseted Wireshark protocols back to default and now it looks like everything is back to normal. No more RakNet packets. The question now is was it just a "fluke" or is somebody spying on me.
