I am new here

Have been battling all weekend trying to figure this out. Does VEEAM have a guide from start to finish on how to set up this WAN acceleration feature.
I have opened up only the following ports:
6165, 6164, 6162, 6160, 2500, 2501, 2502, 2503.
I only want to open up the minimum required.
I started with the default 6165. This port alone is not enough.
I then read on this forum link a few more needed to be open.

Does WAN acceleration need a VPN, or ISP grade private network?
I am new to this product and I primarily want it due to WAN acceleration. I have a ProPartner login. I either do not know where to look or VEEAM don't document well or just assume we know all the steps (I apologise for my tone here, just been a frustrating weekend, trying to research it myself).
So far I have done:
1. The ports as mentioned.
2. Backup Job1 to local c:\backup
3. Offsite Backup Copy Job - which copies the c:\backup\ data to remote repository.
4. Before doing 2 and 3, I created two WAN accelerator (local backup server), and the other on the remote backup server. These setup went okay with no errors.
When I run the Backup Job1 it succeeds.
When I run Backup Copy Job1 it fails with the following message.
I have replaced the WAN IP below with the word "REPLACEDREMOTEIPNUMBER"
