In an appartment building we need to share common equipment (IP intercom with video stream, SIP server, internal web server) with multiple households. Each household has its own internet connection and network stuff.
Households should be able to access the shared equipment but not each others network.
The idea is to have the shared devices/intercom sip server in a separate network, connected to a switch. Also each household gets one cable from this switch.
I am looking for some pointers to help us on the way. Perhaps this type of network has a name?
- How can the household networks 'see' the equipment that is shared?
- Is it possible to connect the shared network cable to a WiFi router in the homes (after some configuring), and if yes how is that 'configuring' called? If no, what kind of equipment do we need?
- Households should not be able to access the networks of the others, how can we prevent this?
- Equipment in the shared network must be able to communicate with the household networks (for example when there is a call the sip server must be able to pass the call).
Edit: a small diagram to show the intention.
ISP---internet modem home 1---switch----------->cable h1 | | | home 1 equipment like printers.. ISP---internet modem home 2---switch----------->cable h2 | | | home 2 equipment like printers.. cable h1---shared switch---shared equipment | cable h2----
Home 1 should not be able to communicate with home 2, but it should communicate with shared equipment. Personally I think the shared equipment should be in a VLAN, as well as every home. Then the 'shared switch' should have some kind of access rules to allow communication between VLAN
shared and VLAN
home*, but not between VLAN
home* and VLAN
Is this correct? How do the homes know how to access the shared switch when they are in a different ip range?
