Edge server network interfaces are not properly configured
<Details>
<Content>Advisor has either detected that all the network interface IP addresses for the edge server are from the same subnets or there is only 1 NIC. Make sure that the server has two network interfaces that are configured with IP addresses from different subnets. See the following KB article for more information.</Content>
