Two-way WAN-LAN connection

Hi, Thank you for your patience with me! I replicated the configuration, and on the WAN side, I can only access the Rut951’s web interface (LAN 192.168.113.1). I also tried another Rut951, starting from scratch, but nothing changes. I can’t reach any device connected to the LAN side (192.168.113.0). In the image I’m showing you, I’m trying to reach one of the devices with the IP address 192.168.113.101!! Hoping to resolve the issue, best regards.
