Multiple Nic Cards On Same Server 2008 Box

[eric23592]

I'm trying to setup up two nic cards. One on the PCI slot and one Motherboard. I wanted to connect the PCI one to router one "IP as follows: 192.168.1.150" and the Motherboard one to router one "IP as follows: 192.168.2.150" Therefore I need some help getting this to work if possible.

I don't understand what you need... Just set up the two different IPs and connect them to the router...

I was trying to have a router with the IP 192.168.2.150 hooked up to the MotherBoards Ethernet Card. Then another router hooked up to the PCI with the IP 192.168.1.150 the other router. So the customer can save data to and from the server on both connections

Wait... are you talking about LOCAL network or INTERNET?

 

You can have two interfaces on your router (eth1 -> 192.168.2.100 and eth2 -> 192.168.1.100) which are connected to your server (motherboard -> 192.168.2.150 and PCI -> 192.168.1.150). This will work. BUT PAY ATTENTION. In this LAN clients must have somebody (the router?) that routes from one network to the other and viceversa. If your customer IS NOT on the same lan (is away, internet), then your solution is quite pointless because the customer will still use ONE WAN connection so if it's broken... you don't have access anymore.

 

If you draw a network diagram I can help you a bit more.

Yes, it's Local Networks and i can't post the diagram because i don't have 20 post yet sorry.

Ok now it's clear.

 

You are trying to load balance traffic on both interfaces.

 

By default windows sends traffic to the first available interface so it will not use both interfaces. What you can do is to bind services only on some interfaces. Let's say webserver + database on nic1 and other on nic 2. this will "load balance" your traffic. If the driver provided by the NIC's manufacture permits so, bind the interfaces.

 

If you want to really load balance (use both interfaces together) you must the balancing tool in windows server BUT pay attention to the router. You must configure it properly and not all the routers permit this balancing.

 

What's the model of your router?

 

I'm thinking about OSPF or IS-IS but actually it can just find the best path and NOT use both connection.

 

Final word:

If you router supports this, create a trunk or pool or whatever is called to merge two interfaces as one and then do the same thing in Windows.

If not, split the services as said before.
