I will try to keep this description brief as there are many factors and the details might get us away from any actual answers:
One of my clients is a library. This library is part of a province-wide network of libraries that share numerous resources and internet connectivity. For use of a number of programs it is mandatory that the library use this network. When the network of libraries was originally set up part of its mission was to provide high-speed internet access to all libraries. That was a long time ago and high speed then is a big bottle-neck now as the whole of our library is only allowed 10 MB down. With 20+ staff and public computer use this is a struggle.
We have access to a fiber-optic internet connection which I have set up all public-use computers (basically any user that doesn't need access to the internal inratnet) on, lightening the load a little but still we are seeing issues.
Here is the question - Is there a way for me to blend these 2 networks and set up routing with regard to web traffic, directing only the intranet site requests over the old intranet connection and all other web requests to the Fiber line? I have worked with a load-balancer for other clients before but to my understanding that's really a tool for spreading all requests between 2 internet connections, not so much specifically routing them.
Any help would be surely appreciated!
