Subject Re: Not able to ping to outside network from system VMs
Date Fri, 28 Feb 2014 08:46:02 GMT
Which zone are you setting basic or advanced ?
My suggestion for you is first make a setup with simple config to get it work.

If you are trying for Advanced zone isolated network,
Try the separate ip range for management and public.
1. Management subnet: ex: 10.147.28.100-120 , gw 10.147.28.1 vlan:28 
2. Public subnet subnet: ex: 10.147.52.100-120, gw 10.147.52.1 vlan:52
3. Dns: use your corporate DNS server, do not use MS.

Thanks,
Jayapal
