Static routing issue

RouterOS General
1

Hi there,

I am trying to get the router on the left to connect to the internet, please see the following diagram.

I have created static routes as displayed on the diagram.
Router on the left can ping 172.22.22.1 and 84.246.245.226, but not 84.246.245.225 and the internet
Router in the middle can ping 172.22.22.2, 84.246.247.185, 84.246.245.225 and the internet.
Router on the right can ping 84.246.247.185, 84.246.245.226 and the internet.

A server connected to the router on the right on a totally different network can ping 84.246.247.185 aka the router on the left, although the router on the left cannot ping the server.

I thank you in advance.

How are your NAT rules configured?
Pings from the left router towards the “right” direction have src IP 172.22.22.2. This is a private IPv4 address, without source NAT to a public IP it won’t be able reach the Internet. And without an additional route covering 172.22.22.2 the “right” router will send its ping replies to the internet instead of back to the middle router.
