Static routes / multiple networks / portforwarding

[therealabdo]

Hello guys

I have an idea for a project and I was testing but no luck

I have flats in a building a small one. I want to connect each flat's network to a camera down stairs.
Each flat has its own network

Like in this photo
As the left side is the flats and the right side is the building internal network

I have done like a small lab
The problem is that only the router which is gateway of the camera (10.10.10.100) can see the camera. Other routers cannot
However, if i change the gateway to another router that new router would be able to see the camera

I have tried the static route as mentioned here but it worked on way only (from right to left)

Any help

Not sure what the LAN/WAN internet modem bit is all about? From your description there isn't a WAN?

Do you have static routes defined both ways? Both networks need to know about how to get to the other network.

What camera are you using?

What camera are you using?

Using the Foscam IP camera

It is working if i change the gateway but only to the gateway connected left handed network

I defined static route it only works as you may say from right to left.

You need to ensure you have routes in both directions. Ideally you would set the routes up on the switch that connects it all.
