We are building a network inside of vmware/vsphere 5.1 and need some guidance in whether we should expand the subnet mask or manage everything through a routing table.
Core Devices (router, switches, servers, etc.)
Data (PC's, printers, etc.)
VoIP (phones, etc.)
Firewall (virtual network device)
We currently have a NIC on it for the core subnet. Do we/can we expand that NIC's subnet mask to say, a /16 in order to fully communicate with everything? ...
Or do we create a NIC on the firewall for each subnet and add routes in the router? ...
Could we also bind a NIC to multiple subnets?
Just not sure what the "best practice" is when everything is entirely virtual, including the router and firewall.
