Block the user on Block Labs platform.
Hello, I'm using a Huawei B525 and need to restrict access from a specific user. I managed to adjust the DHCP settings to assign an IP range from 192.168.8.111 to 111, which is my current IPv4 address. However, I want to block all users except that one. I tried starting from scratch, but it's not straightforward. Can you help me figure out how to set this up properly?
Sadly, most consumer routers don’t let you turn off LAN ports. But you can apply QoS rules if the device is acting as a wireless client to block its MAC address from accessing the internet. As a wired client, you’d need a managed switch. From there, you can connect remotely and disable the port when needed.
Navigate to Settings > Security > Device Management, and you’ll find options to permit or block devices that have just connected.
If you're unfamiliar with switches, it seems you're in a tough spot. No matter your reason, securing this user is crucial. With such limited knowledge, the safest step would likely be to switch them to Wi-Fi and block their MAC address—this will cut off their internet access immediately.
Because I don’t understand these things doesn’t mean I won’t try. I’m not the type to shy away from challenges—I might never master everything, but I’m willing to learn. If I want to do something, I won’t waste time researching everything; otherwise, forums would be unnecessary. And it’s a PC that doesn’t support wireless connectivity.
If you're set on it, essentially a device switches connections to various downlink speeds—like 4, 8, 16, or more. For clients, servers, or network gear, this means converting uplinks into compatible downlinks. The four ports at the base of your router function as an integrated switch, though it's likely just a placeholder you can't adjust. A managed switch gives you control over traffic, security, and monitoring, which is useful once you get the hang of it. You can also disable interfaces if needed by connecting the router directly to the switch. Managed switches tend to cost more, but brands like Ubiquiti have budget options for hobbyists, and eBay offers used models at a discount. If you buy from companies like CISCO, you'll need to learn their command-line interface to configure them. Fortunately, enabling or disabling ports is straightforward with simple commands.
It looks like you're trying to avoid contact with someone on your local network. That approach isn't ideal, especially if it's not your own setup. It seems like you might be attempting to block a family member or someone close, which isn't acceptable. I don't think these discussions should be encouraged here—it violates the community guidelines.
You think it's not my network? I'm going to block someone who's using all the internet. Every time he's on his computer and stays connected, I experience lag with a 30 Mbps connection. I've asked him, but he doesn't realize he's consuming so much bandwidth. I won't tolerate 200 ping when someone is consistently using 30 Mbps. My performance drops from 30 to 70 ping, which is unstable. I work remotely and use cloud services, but they're extremely slow. If you don't want to interfere, you definitely shouldn't be here—this is the main reason I started this forum.
