Situation :
Dell 1950 server 2 dual cores and 2 nics.
Installed esxi 4.1 from dell itself.
Host is up and running on a external ip and can be viewed by vSphere client.
Now we have a qnap nas server we wish to attach as datastorage in a local network.
Example : Nas ip = 192.168.1.108 so 2nd nic must have 192.168.1.103
Whatever we do, we can't get the datastorage to work.
Tried different settings/ip's, also adding 2nd virtual switch commited to acces the local network.
We can't ping the local network.
What do we forget or doing wrong here ?
At home we tried and it worked fine with another nas, but only 1 ip was set at that time.

If you access the console for ESXi can you ping the IP for the NAS?

Are the "Nas ip = 192.168.1.108 so 2nd nic must have 192.168.1.103"
addresses on their own subnet?
