Hyper-v Network connection

I have a server that i run hyper-v 3.0 on it and attach 4 NIC on my server and I install 4 vms on my server.

I have 5 public IP addresses and I want to use my vms on the internet.

how configure my NICs an vSwitche?
I have configured 4 vlan for each vm and dedicate each NIC for each vm,and setting external mode for vswitch,but i cant see them on the net.
