alright so, I tried to join in with a friend via steam to play some custom zombies with him and shit but the problem is I can't join him and he can't join me, we did the firewall fix and haven't tried port forwarding and shit but every time we try to join each other via invites and shit (yes we have each other added ingame) so he sends an invite to me and i get met up with it saying that the game isn't available, is there some fucking 2020 patch or do I have to use LogMeIn Hamachi or do i just have to wait till Black Ops 3 goes on sale and buy that

You shouldn't have to do the Firewall thing, First thing first.

1. Add your friend on WaW by his/her/64 other genders name on WaW NOT Steam.

2. Create a OPEN lobby for you two to play.

3. If your friend lives on the other side of the world then WaW may disconnect you (I believe max 300 ping?) but this has never applied to me

I have them added on WaW and the connection is from NZ to AUS, we've both created an open lobby but the thing is it doesn't show up on the browser and when we invite each other it still doesn't work, is there a patch i can use or something similar?
