Server Load Balancing Question

[Southy]

I would like to setup a machine with either windows 2k3 or 2k8 server or linux to act as a router and run services such as dns,dhcp, etc. I would also like it to do load balancing on both sides, for my incoming and outgoing connections. I have 2 dual NIC cards installed to make a total of 4 Ethernet ports, 2 for incoming and 2 for outgoing. The 2 incoming connections will be external ips and then the 2 internal connections will be private ips that will go to a switch. I have setup load balancing with 2 Ethernet connections before but not 4. I'm sure it is, but is this possible or is there special configuration steps needed to make something like this work?

Depending on the server and the NIC's you should be able to 'team' them together to create two logical NIC'S that give you double the throughput.

Failing that you could ensure that both your routes out have the same metric and will then be load balanced automatically.
