web client virtual machine console timeout

Hi,

I'm on vcenter 5.1

On the web client, when I try to open a virtual machine, It print "connection timeout".

I use wireshark to see what happened.

I saw that the web console try to connect to my vcenter on the 2nd network card (and it is not possible).

Di you know why the vcenter send back it's 2nd IP network card ??

I repeat, the problem is only with virtual machine web console, not all the vsphere web client.

Thanks you
