A client (in my case a windows machine) on the second vSwitch can't get the MAC address of the default gateway on the first vSwitch. Sniffing the traffic shows the arp broadcast from the windows machine making if over the linux bridge and getting responded to by the cisco gateway but the response never makes it back over the bridge. Watching the mac table in the linux bridge shows it mistakenly associates the mac address of the windows machine to the wrong port (eth0 in my case, eth1 is the vNIC plugged into the switch with the windows box) > Im not sure where the issue is; its really pretty simple setup. Am I missing something simple? Is there really a bug here? > Thanks! You do not wan to bridge in a VMWare environment, it will only drive you to an early grave. I've blogged my experience with this problem at http://robert.leblancnet.us/ you will need a google wave account to view it. In short use proxy arp instead if you can. Robert LeBlanc Life Sciences & Undergraduate Education Computer Support Brigham Young University I've also had the exact same issues. However, if I move one of the vNICs to a vSwitch using a different physical nic, then the issue seems to go away.
