I need the expertise of a networking master to help me potentially overcome a networking challenge!
I work in a place where we currently get our internet from another business in our building. We do similar work with common customers, so being on the same network is extremely beneficial as it allows us to locally share large media files with each other.
Times are tough, and the cost of sharing this service with the other company has become a problem, so we're planning on having our own, less expensive (and slower) internet service installed.
What I need to figure out is if it is possible to do this and still maintain our LAN connection with the other company for speedy Gigabit Ethernet file sharing. Ideally, all of our computers would grab IP addresses and internet connection from a router on our end, and all of the computers at the other company would continue to use their existing internet service.
Is this possible, and if so, how can it be achieved? I'm guessing with my limited knowledge that it might involve bridging, manually configuring each computer's NIC, or something similar. Lots of points and kudos if you can help me with this!
