SCCM Secondary Site ports requirements

I have recently deployed SCCM 1802 on our primary site with seperate SQL 2014 Server. Now, I need to deploy secondary site for my remote location. I need to know which ports will be opened between primary site server and secondary site server? Do i need to open any port between SQL server and secondary site server as well? And what will be the direction. I have read articles which says ports 443, 445, 1439 and 4022 but all are when primary site server and SQL server are co-located. I have seperate servers on primary site which is confusing me. On secondary site database will be co-located.

I am a bit confused with your last sentence. You may not even need a secondary site with Current Branch (1802). You only need it if you want a Management Point or Software Update Point locally, or if there are more than 500 clients at the remote site, i.e. roles that create lots of traffic. Otherwise you can use another Windows server with the DP role added keeping things much simpler. Microsoft flattened the design in 2012 to make things easier.

As for ports you only need these: TCP: 4022 (SQL), 1433 (SQL), 135 (RPC/WMI), 445 (SMB).

So not 443 or1439.
