merge 2 internet connections into 1 network?

[sizzors]

You are not clear on what you are expecting to achive in combining the two connections. You do not get 4Mbps if that was your goal. You would get the ability to download 2 separate files at 2Mbps rather than one perhaps. You can't double the bandwidth for a single use, only provide twice the connections.


If you are serving 50 computers you might be more interested in Network Load balancing at the server/router level. This would be the most appropriate use of two separate ISP connections. Its going to be about how much money you want to spend on Gear and software. Recomend a Cisco multiple Wan router if you dont do a Server. Either way you will set a metric to when the other connection is utiliizied. ( Most servers have software built in)

You could try to double home a individual Nic card or install two Nic cards per machine, but who wants to admin 100 plus nic cards and the associated settings for each application that wants a internet connection. Most application software usually locks in one single connection if it needs to reach out to the Net and would need your intervention to set or change it. Its going to want to default. If you wanted to create yourself a job I suppose that would be a way of doing it.

Easier to utilize two Nic cards in the Server, or Admin the connections at the Multiple Wan router. You could then traffic shape by allowing or deny routes based on IP's outgoing requests.
