Two separate networks connected via a single link
Two separate networks connected via a single link
This situation involves adjusting my internet usage based on different network needs. I plan to separate work traffic from personal use, especially when accessing the web. My current setup uses an Asus RT-AC88U, which seems to lack multiple LAN options. Even with more features, I want to apply unique limits and filters for each connection. At home, bandwidth is virtually unlimited, but I need to manage URL filtering through workarounds like WindowsUpdate adjustments. There’s likely VPN and regular traffic on the same line. I have several IP devices besides my laptop, none requiring high bandwidth. I’m wondering if a dedicated router would be necessary for full control or if Quality of Service (QoS) is enough.
You require a tool that enables VLAN creation to isolate your work device. A quick online search shows routers with VLAN support.
You're questioning whether VLANs are being used properly. You'd like distinct physical devices for each network, connecting them only through the router, not with multiple virtual networks on the same hardware.
They likely have a software tool for this, but it probably requires high-end equipment, adding extra expenses unless you already have compatible gear. A straightforward approach would be linking two routers to your modem, which would generate separate networks while treating both similarly to the public internet.
I tried something similar but slightly different. I used two network cards—one for each network—and my PC handled one while the router managed the other. I set up the second network to be offline without internet access. I’ll clarify it further: Router (home network) → Network card #0 → PC → Network card #1 (secondary network, no internet, controlled by my PC). Both networks are completely separated, so devices on the home network can’t reach those on the secondary network, and vice versa, only my PC can connect to both.
Is this double-NAT setup? The modem needs to operate in router mode to allow additional connections, then you’d have two routers, each handling one network, with the modem managing the others. I’m uncertain about running everything through the modem/router and preferring a simpler configuration. Essentially, I’m seeking a solution for a single router that can manage multiple LANs on a per-socket level.
It might require double NAT settings, but the modem shouldn't need special handling. Placing networks one behind the router and another on the modem only provides unidirectional security. Devices on the router can reach the modem's features, while modem devices would appear accessible to others, not restricted.
I don't believe this approach would suit me since both networks would require open net access. It really feels like a bad plan if it can be skipped. Multiple layers... could it cause issues? How would it affect my gaming latency? Honestly, I should check Google for more info. My main worries are: 1) I don't want my private network to be monitored by anyone, not even if they can see work traffic. 2) I don't want any performance problems on the home side from work-related tasks. That's why I set a bandwidth cap. Still, this wouldn't meet the second point, so it would be rejected.
I also worried about this during the recent switch to a standalone router positioned in front of the ISP modem. A quick test before and after showed less than 1 ms—completely undetectable. My approach seems effective based on my understanding, though I’m sure other factors could play a role. Your thoughts and suggestions would be appreciated.
I'm struggling to locate anyone who has addressed this issue, so it seems like I'm not concerned. Using two routers—one for each network—would work, and double-NAT is still an option if needed. I’m hoping for a single router that could handle this without adding another layer. If I want to push it further, I might revisit pfSense.
