At the moment I'm managing a little network (7 hosts) linked to the outside world through a normal ADSL connection. This little network is inside a consulting room in which works 4 medic + 2 secretaries, recently my region decided to give internet connection for free to all the consulting rooms they can reach.
Now, my problem is that the region gave me 4 ip adresses but I have 7 hosts, what is the best way to connect all of them to the outside using all the 4 ip adresses? A load-balanced proxy? Routing 2 network?
