@stephenw10:
What firewall rules do you have on WAN? Any unsolicited traffic on WAN should be blocked by default so why is it showing as 'in-pass'? The obvious answer the that is that it's not unsolicited, something on your LAN is asking for it. Why then is that traffic not showing up on an internal interface?
If you didn't know Akamai are a content distribution network used by many companies including Microsoft to deliver updates service packs etc.
I would guess that one or more machines on your internal network has got stuck in Windows update loop, downloading the updates, failing to apply them and then trying again.
If you go to Diagnostics: States: rather than state summary, and then filter by the offending external IP you should see the NAT state showing your internal machine requesting the traffic.

I originally assumed it was a PC, tablet, etc on the LAN causing this like you said, but nothing ever appeared to be sending or receiving anything. It's stopped as of now so its a bit harder to check on, I am not sure what actually stopped it though, and whether or not I had any part.
Using States and filtering by a few of the IP addresses only showed traffic between my public IP and the offending IPs. I'm not sure if this is because it's been a few hours since it stopped, I assume it gets cleared out a bit?
Below is the Traffic graph for the last week on the WLAN(i dont have anything on the wired LAN).
