We have a Dell Machine that is running ESXI server 4.0. This server before was sitting inside the company's firewall, and we were able to add the additional storage using network file system (Vsphere client > Conf> add storage). The additional storage is a Netgear NVX Raid unit.
Now the issue is this ESXI server is connected in DMZ environment which is outside the firewall. We can connect to this server using Vsphere client from inside the firewall, but when we try to add additional storage we get an error message. Is there a specific port that needs to be open for mapping additional storage via NFS? OR is there a range of ports that needs to be open? Any tips would be nice.
