Hello everyone (UK), I'm setting up a home network with two routers, each having its own SSID. I want them to remain isolated so they can't see each other's devices, files, or printers. My main router uses the HG633 from talktalk, and my standard phone line socket has the DSL-3680 also from talktalk. I'm wondering if connecting them via an Ethernet cable between their LANs would work? Any advice would be greatly appreciated, @ehazard

The simplest approach involves three routers arranged as follows: Phone line connects to an RJ-11 WAN port, Modem - DSL-3680 sends data to a RJ-45 LAN port #1, then an Ethernet cable links to the router's LAN port #1. Next, Router #1 connects its LAN port #1 to another Ethernet cable and sends traffic to the second router's LAN port #2. Finally, Router #2 connects its LAN port #2 to a third Ethernet cable that feeds into the third router's LAN port #3. This configuration uses two routers, each handling separate parts of your network. Ensure all routers have distinct subnets—such as 192.168.0.x (with IPs from .1 to .254)—and keep NAT and firewall active to maintain traffic isolation.

It's important to remember this arrangement is quite poor, and most gaming options may not function well.

Sure, I understand. You’d need to set up unusual port forwarding, and even then, it might become overly complex to manage and maintain properly.

You're asking why you're connecting two different types of modems together. The HG633 works with VDSL, while the DSL-3680 supports ADSL. Using both might not be necessary unless you need specific features from each.
