Create multi homed proxy with fixed internal IP

We wanted to create a multi-homed instance connected to proxy-net and internal-net because the nfs-mounts are shared via internal net by the server. However, the NIC on internal-net wasn’t getting an IP assigned automatically and this was creating an issue for NFS server to communicate with the clients. So we created a port and assigned that port during instance creation
