Tips for dividing your LAN network
Tips for dividing your LAN network
Hi there, I’m seeking some guidance on dividing my LAN setup. Back when I shared the network with my sister who lived above mine, it worked fine—she could check her IP cameras, use my printers, and access the NAS. Now the place is renting out, and the new tenant will move soon, giving me time to handle things. They asked for internet access, but they want me to keep them separate from my network and restrict their bandwidth. Since I can’t change the ISP router, I’ve been searching online about switches that support port-based VLANs (like Netgear GS105E or TP-Link SG105E). Will installing one between my apartment and the tenant’s space solve the problem? Any other suggestions would be appreciated. Thanks in advance! P.S. My English isn’t great, so I hope you understand.
VLANS could function, but a firewall (router) is necessary for control. Why can’t the ISP’s router be adjusted? At least switch it to passthrough mode. This would let you run your own router behind it and avoid double NAT. If possible, you’d be able to use VLANs as intended.
Hi, thank you for your reply! Right now I can't modify the modem since it controls the phone line, and the telecom provider is upgrading fiber in my area, leading to several issues this month. They’ll need a new modem installed to confirm the connection and open a support ticket if needed. I’m open to using another router or switch if that’s an option.
Modems and routers serve different purposes. If you have a single device in one box, it might be a modem/router combo. In this case, you can switch it into passthrough mode so your own router works behind it smoothly. You don’t need to enable passthrough, but doing so will double NAT, which can sometimes affect certain services like gaming. Researching double NAT will clarify what’s happening.
I checked the ISP modem/router and found a way to disable Nat. Switching to a new router connected directly to the modem and using a VLAN for the tenant’s Wi-Fi should help. For affordable options, consider budget-friendly routers like the TP-Link AR285 or the Netgear Nighthawk R7000.
Could the tenant have their own internet service? I believe it’s not wise to let them use yours, especially if they engage in any wrongdoing—then responsibility falls on you.

You have two choices: use VLANs or supply them with a dedicated internet connection.
