I'm setting up a network in my apartment building in the next few days.  The building has three units.
 
What I'd like to accomplish:

• Run all of the units with one internet connection (account)
• Set up VLANs based on ports so each apartment is on its own network

Can I accomplish this with just a managed switch?  Will it look after DHCP?
 
Thanks!

Bump.  Anyone?
