I want to setup a 2 site system that is high secured.
This is what I've done yet and what is working:
Site 1: ESXI 6.5 test server whit 1 W2K16 server (not yet dc) and W2K16 server as backup proxy (both in VLAN1)
Site 2: Backup and Replication server 9.5UP3 and QNAP with CIFS in VLAN 2
Between site 1 and site 2 there is a vpn over wan.
Some ports are open to commmunicate.
I have create a repository on site 2 with the qnap (cifs).
I added my ESXI 6.5 host (later it will be vcenter) and I can see my machines at site 1.
I can start a backup job and I can restore a file form that job.
Question:
But now all the data is going over from site 1 to site 2 over the wan.
I want to create a VLAN3 at site 1 where another qnap is installed.
If I create a backup job of VM at side 1, I want to store the data at site 1.
Which components do you need to install?
Repository server?
Gateway???
Which ports must I open (not the hole chabang please

Thanks for your time !
