Yes, this upset me so bad when I was trying to get it to work, but we finally figured out what the setting was. I'm using VSphere.
If you do this on the vSwitch itself (uncheck the box next to Reject) all the machines connected to it will start to see ALL the traffic on the switch. Firewalls connected to this vSwitch will start to RST packets that are not destined for them. You will lose connection to this ESX server then also because the firewall connected to the vSwitch will start to Deny all the VMware server traffic itself. Try not to do that :-).Message was edited by: sliedl on 4/19/12 10:53:38 AM CDT
