Please check the version of VDP is compatible with vCenter Server.<br />
<br />
Also please note VDP is very poor, and the worst product of the VMware vSphere product portfolio!

Andrew,<br />
&nbsp; The vcenter server is 5.5 and the VDP ova is version 5.8. &nbsp;How do I tell if they are compatible?<br />
<br />
Also, we have never used VDP before, but I am trying it out just to back up a test lab. &nbsp;We use Veeam in our production environment and backup exec for test. &nbsp;Just thought I would give the VDP a try in the lab.<br />
<br />
Is there a better product than Veeam for replication and backup?
</div>


<div>
I use both, veeam is better, use vdp for testing like you.
</div>


<div>
vCenter Server 5.5 and 5.8 is compatible, although to check the actual versions, you need to check the <a href="https://www.vmware.com/resources/compatibility/sim/interop_matrix.php" rel="ugc nofollow">https://www.vmware.com/resources/compatibility/sim/interop_matrix.php</a><br />
<br />
Good Luck with the VDP test, it's very poor, especially when you start to fill up the repository and it breaks!<br />
<br />
Veeam Backup and Replication is very good, but has lots of features you may not use, Veeam have had the market for a while now, BUT Nakivo Backup and Replication, is hot on Veeam's heals, and taking business away from Veeam - <a href="https://www.nakivo.com/" rel="ugc">https://www.nakivo.com/</a><br />
<br />
and they are the first vendor to integrate Backup Appliance into a NAS, e.g. Western Digital or Synology, we are now moving from Veeam to Nakivo.<br />
<br />
You always need to backup to some other storage platform to protect yourself against single point of failure, and it seems a marriage made in heaven, to incorporate the backup software into the storage product where the backs will be stored, saves a VM, Windows or Physical server!

<div>
Back to your issue, when you installed vCenter Server, did you use different values from the standard ports ?<br />
<br />
The issue is often caused by different ports in use on vCenter Server, and VDP expecting to use standard ports.<br />
<br />
You may need to add custom firewall port rules to VDP<br />
<br />
e.g.<br />
<br />
you need to modify /etc/firewall.base (line 212) and add your port rules<br />
<br />

<pre><code class="code-1 nolinks" id="code-20-41487497-1"><span>exec_rule -A INPUT  -p tcp -m multiport --dport 53,80,81,443,444,123,5555 -j ACCEPT</span>
</code></pre>
</div>


<div>
Andrew,<br />
I saw that as a potential fix. &nbsp;May folks suggested change port 80 to port 81 and port 443 to port 444 by editing the firewall.base file.<br />
<br />
Not sure where this file is or how to edit the file.<br />
<br />
Is this done at the command line on the VM or through the browser? &nbsp;I assume through command line, since I can't get the browser to let me finish configuring the product.
</div>


<div>
Andrew, I do not know if the ports were altered during the install. &nbsp;It does sound vaguely familiar, but the engineer that set that up originally is no longer with us.<br />
<br />
Is there a way to verify what ports vcenter is using, so that I can then configure VDP to use the same ports.<br />
<br />
Also, I had seen the fix that you indicated above using VI, but I don't know Linux or how to use the VI command line. &nbsp;I tried from the command prompt to enter VI /etc/firewall.base, but it returned two pages of text that was incomprehensible to someone that doesn't speak linux. &nbsp;:)<br />
<br />
So maybe the better start would be to verify what ports vcenter is using.
</div>


<div>
Okay, I was able to determine that port 80 was set to port 8000. &nbsp;I set VDP to 8000 and it worked fine. &nbsp;Thanks for pointing me in the right direction.
</div>


<div>
If you are not familiar with Linux and vi, then we would recommend the use of <a href="https://winscp.net/eng/index.php" rel="ugc">WinSCP</a><br />
<br />
this allows you to login to Linux computers, via SFTP, browse the files, and edit them from Windows.<br />
<br />
as for ports required, you could use <a href="https://technet.microsoft.com/en-us/sysinternals/tcpview.aspx" rel="ugc">TCPView</a> to verify which ports are active in vCenter Server.<br />
<br />
These are ports VDP uses to connect with vCenter Server, all our TCP<br />
<br />
80,7444,<br />
<br />
vCenter Server to VDP<br />

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
