Per the "Modular Disk Storage Manager" section here   , you need to open network port 2463.
Good morning, I have an MD3000i SAN that is at a remote location going through two firewalls (PFSense). The firewalls are connected via OpenVPN tunnel. I can ping the IP from site A which is where I am located and there is a return path from the LAN subnet that my servers (and MD) are on in Site B. I have the MDSM installed on a Win2K3 server here (no firewall on the server). It will not find the SAN on the far end. Is there a port that needs to be opened on my firewalls in order to get the management piece operating?   Thanks in advance.   Scott
