Trying to connect two routers (self.networking)

Hi all!

I have 2 ISPs with their own routers.

Router A: 192.168.0.1/24

Router B: 192.168.20.1/24

I have my servers plugged into Router A and all my endpoint and users' devices connected to Router B.

I want users connected to Router B (192.168.20.1/24) to have access to server 192.168.0.90

I thought plugging a LAN cable and connecting Router A and Router B and then defining static routes in both routers would solve the issue.

However, at the first step itself I have an issue. When connecting the routers via a LAN cable, both routers dont get any IP.

I was also referring to this post on superuser. Though Router B is capable of creating subnet and static route, I am not sure if Router A (Archer XR500v) is capable of creating a subnet and/or a static route.

You are going down a road of headaches here. Do you absolutely have to use this hardware to complete this setup? If not please consider getting a dual-wan load-balancing router. Cisco makes a nice one, tp-link has a fairly cheap version too. You can use the provided routers behind a firewall as better wireless AP nodes.

Yeah, this looks like consumer grade crap. I'm a simple home user, and I've found a lot of value in entry level enterprise gear (Mikrotik router, Ubiquiti AP).

OP, if your org is big enough to need two ISPs, you're big enough to buy enterprise hardware. It doesn't need to be expensive, for example this TP-link router can do up to 3 WANs (~$60 on Amazon) and I use the Mikrotik Hex S (~$70; it can do at least two). Separate your router and AP and you can upgrade each independently as needed. That said, configuration will be more complicated (esp for my Mikrotik, not sure amor TP-Link) since they're designed for power users, but there are lots of good guides online.
