I have 3 internet networks from 3 routers. I have 1 static IP from each network. Can I make one static IP as Virtual IP (cluster IP for load balancing) and other 2 static IPs as physical IP address (2 node servers) ? If yes, any ports should be enabled? Any help?
I have researched and found that different SubNet IPs load balancing not possible with Windows OS NLB feature, but possible with any other LoadBalancer which is not related to Windows OS NLB.

So I have a dedicated server with 3 ip addresses, 1 belonging to the dedicated server and 2 additional ones for virtual machines.
How can I assign one of the free Ip addresses to a specific virtual machine?
I tried making a VMkernel NICs for one of the ips but was not sure as to what i was doing since im new to this.
Hi and ty for your reading,
I'm a beginner in virtualization and as part of a project I have to configure the IPs of a physical server and 3 virtual machines on Hyper-V in an internal network.
My question is, do I need to have a DHCP because I don't want to have a particular domain?
Which IPs and gateways do you advise me to use, considering my number of machines ?

You should use a subnet like 192.168.99.x with a mask of 255.255.255.0.
Enter your IP manually and you won't need a DHCP.
I am trying to understand VXLAN functionalities.
All cases related to VM communication through VXLAN that I can find on Google are related to the interconnection of VMs on the same subnet.
My case study would be 2 hosts, each one hosting 1 VM.
VM1 on host1 has IP is 10.200.1.2/24, and VM2 on host2 has IP is 10.200.2.2/24
Can I make the two VMs communicate through a VXLAN?
VXLAN is layer-2 tunneling across IP featuring virtually unlimited subtunnels (VLANs).
If you want to connect two nodes (virtual or physical) in different subnets you use a router. If you can't route them directly (e.g. private IP addresses across public IP network) you use layer-3 tunneling or VPN.
With both end nodes in different subnets there's no point using VXLAN.
I would appreciate any help with configuration of MS Windows Server 2012 R2. I have tried more solutions, but any of them were not so appropriate.
The idea is on the attached schema belove.
Server has AD.
Server has 2 NICs. Both are configured on the same subnet. (192.168.1.0) with IP addresses manually configured as is on the schema.
NIC 1:
IP:192.168.1.254
MASK: 255.255.255.0
GW: 192.168.1.1
DNS 1: 192.168.1.254
DNS 2: 192.168.1.1
Metric: 10
NIC 2:
IP:192.168.1.154
MASK: 255.255.255.0
GW: no
DNS 1: 192.168.1.154
DNS 2: 192.168.1.1
Metric 100
NIC 1 is connected to router from ISP 2.
NIC 2 is connected to router from ISP 1.
The goal is: All clients should have access to the internet via ISP 2. Some clients have acces also via ISP 1 via VPN. ISP 1 does not provide public static IP address. ISP 1 yes. So only via ISP 1 is possible to access the local network via VPN.
How to configure server to accept VPN connection and route whole traffic from VPN to local and to ISP 2?
Also I have tried 2 subnets (for VPN clients 192.168.2.0, for local clients 192.168.1.0 but no success to setup routing).
Thanks.
This is not how you do this, rather you need a firewall that supports multiple WAN interfaces - examples are Peplink (great if you also want to load balance the ISPs or get increased throughput by leveraging both of them) other examples include the Cisco RVx series, or Zywall USG series.
Then your server can have one IP on the LAN (as it should) and you can use the ACL/Firewall rules to control what goes in/out which ISP.
I have 4 virtual machines, a client using windows 7 and 3 servers, one of which is a core server installation the other two are standard windows servers. I need to give all machines a static IP address from the range 192.168.0.0/24 and make sure they are all on a private internal network called intnet.
Can anyone give me general guidelines on how I would go about doing this?? As in how to actually set up a private internal network for these machines and then assign each VM to this network?? I am assuming that the network is created in the client windows 7 machine and then the servers are added to this network but i can't seem to find basic information on how to go about this on the net.
Any input appreciated.
VMWare already does all this for you.
It creates:
Two internal subnets
a virtual IP address in the first subnet that is bridged to a real NIC of the host.
an IP address for each VM in the second subnet.
routing between the two subnets.
There is a program called 'Manage virtual networks' that does what it says.
