A non-profit organization I help to run may need to share its new office space by subleasing a portion to an unaffiliated non-profit. My organization expects to provide internet access to its tenant. The organization will need a network that allows it to share files internally among a few users (no more than five for now) and likely to share a printer. The organization also wants to offer its visitors wireless internet access without letting those visitors onto the private parts of its network. Installing two internet connections seems like a needless expense so hopefully one connection will do.
How can the organization isolate the private parts of its network from its tenant if they share one internet connection? I assume that if the tenant just plugs its computers into the cable modem for internet access, the tenant will be able to intercept all the unencrypted files travelling on or stored on the computers on my organization’s network unless there are safeguards.
How can the organization provide wireless access to the public without those people being able to intercept its internet or network traffic? Is this as simple as installing two different wireless routers with different passwords on the same internet modem? Would this allow the public users to trawl through the private parts of the network?
Low cost and ease of use are priorities. Clearly I’m not that technically sophisticated but I’m among the tech savviest people they have. Ideally we’d find something that could be installed without requiring a ton of maintenance or ongoing service fees.
Thanks in advance.
