Discovery of vCenter thru a firewall - ports needed?

We've successfully Discovered vCenters w/in our firewall, but now need to do one outside our firewall. 
To date, I requested to have the following ports opened, however, (Jakarta) Discovery is still failing, so am asking which ports must be opened for a successful credentialed Discovery?  

TCP/22 - SSH

TCP/135 - WMi

TCP/445 - WMi 

TCP/443 - vCenter

TCP 902 - vCenter

The expectation is we will start with the vCenter and then move on to a few stand-alone physical servers running Windows or UNIX. 

Thanks.

By default, the VMWare - vCenter Datacenters probe runs on port 443, which is the standard port for the https protocol. The port probes for vCenter run on these ports:

  • vmapp6_https: 9443
  • vmapp_https: 5480

vCenter discovery can be triggered in two different ways: from a process classifier or from a port probe.  If the process classifier is triggering it then 443 is the only port you need open.  If it's being triggered by a port probe then you also need port 9443 open.

Steve, thanks ... how would I know if Discovery is doing a port probe or process classifier on my vCenter environment?  We are on Jakarta.   

AFAIK process classifier determines if vCenter process is running on the host being discovered. If that is true, subsequent probe VMWareProbe-VMWare - vCenter Datacenters is launched against the vCenter to get:

VMs, explored by the "VMWare - vCenter VMs" probe,
clusters, explored by the "VMWare - vCenter Clusters" probe,
datastores, explored by the "VMWare - vCenter Datastores" probe, and
networks, explored by the "VMWare - vCenter Networks" probe.

This probe's implementation is located in a MID server script include named VMWarevCenterDatacentersProbe.

Thanks ... I have our SN admin see if he can look at the code to determine which ports it goes after. 

By default, the VMWare - vCenter Datacenters probe runs on port 443, which is the standard port for the https protocol. The port probes for vCenter run on these ports:
