Networking issues between CentOS 6.2 and Windows7 WS8 hosts?

Hi all,

 

I'm having a strange issue crop up between VMs built in Workstation 8 under Windows 7 and opened in the Linux version (on CentOS 6.2).  The VMs are two ESXi 5 hosts and one FreeNAS filer that I built for a teaching scenario. 

 

Under Windows, all of the VMs can talk to each other nicely using a few LAN Segments I set up for iSCSI, Production and Management LANs. 

 

If I open the VMs on a Linux host with the same LAN segments created (with the exact same names), the ESXi hosts cannot connect to the iSCSI portal on the FreeNAS filer.  I can ping the iSCSI portal from a management VM (Windows XP) and from other VMs that I connect to those LAN segments (even VMs brought over from the same Windows-based Workstation 8 host). 

 

I've poked around in the forums and found a couple of threads mentioning assigning group rights to the VMNets under Linux but given that they are LAN segments, I do not think this applies.  I've set up various host-based VMNets to try and work around this issue but have had no success.  I'd like to avoid bridging the VMs to an external network just to facilitate teaching in a Linux environment.

 

Anyone have any ideas?
