What do I need to whitelist to allow Call of Duty: Black Ops 3 to connect to servers?

Call of Duty: Black Ops 3 servers are being blocked, I cannot play online at all. My Internet filter is my main suspect. I have set up port forwarding through my router and the same issue is still happening.

What address do I add to my Internet Filter whitelist to stop this from happening? Unfortunately I cannot just simply allow a particular application to have access to all connections through my filter. If I add the server address to the whitelist, I can stop my filter from blocking it, but adding Black Ops 3 to the whitelist would be so much easier.

I'm not on a university campus. I have not tried disabling my filter.

Can someone tell me what it is that I have to allow? I have asked this on a lot of different places with absolutely no response.

It would be helpful to know what kind of firewall is blocking your traffic in order to get more specific answers.
Anyway, you can't just whitelist all CoD IPs. There are simply too many possibilities and you'll have a hard time figuring them out. And even then it's not guaranteed to work, because the ports required are probably still closed.

It is common practice to set up port forwarding.
For CoD that would be the port 3074 (TCP and UDP). For multiple devices on your network you can as well forward ports 3075, 3076,... for those (for best results, if you're playing at the same time).

If you're just using a Windows firewall with too strict rules you can simply whitelist the game executables there.

Activision has a pretty good knowledge base about all this.

Hey everyone :) I found a solution!

I emailed a representative for my filtering service for the last few days and have found a solution! By uninstalling my filter and downloading an experimental version from a hidden customersupport account, I was able to get my filter from blocking CoD. :) Cheers!
