I have 2 Cisco RV042 routers, each with its own subnet. 192.168.230.x and 192.168.231.x. The gateway is 192.168.230.240. I'm trying to give the 231.x internet access. I want to keep all other traffic separate. How can I accomplish this? I've tried everything I know how. I assume there needs to be a route to each?

Have you tried to create a static route?

I wasn't sure how to do that on this model. They seem to be small business/consumer grade. With the configuration that I have currently, would a static route resolve the issue? Is the gateway setting correct on R2,the 192.168.231? It was suggested I may need a different gateway but I'm not sure what that would be or how to figure it out. Thanks!

Let me back up a bit. I inherited this network. I have a 48 port switch, connected to R1,and R1 patched into the wan of the ISP. R2 only has a few deviceson the 192.168.231,but they need internet access. Someone had patched a cable from R1 to R2 to accomplish this, however the network traffic wasn't separated. R2 could pull DHCP from R1s subnet. I removed the patch cable. Is there any way to accomplish what I'm asking with the equipment I have? I assume at some point this worked but something changed in the setup.

Here is the Cisco Knowledge Base on how to configure Static Route for your router model.

Thanks, apologies for the duplicate post. So if I reconnect the patch from R1 to R2 and create the static route will that prevent the traffic from crossing? With the patch plugged in R2s subnet was pulling DHCP from R1s LAN and assigning it an address in that subnet.

What kind of internet do you have coming into your demarc point? Cable, DSL, or Fiber?

From what you've posted sounds like R2 is acting as a DHCP Relay. You need to check if the DHCP Relay functionality has been enabled.
