The ISP cable is connected to a Netgear router (main router, DHCP enabled). From this router goes out two cables, one for a server with static IP 192.168.1.3 (Windows Server 2012, with 2 NICs) and another to a wireless router (configured as switch with DHCP disabled).
From the server, in the second NIC, goes out a cable to a switch where is connected several computers, with static IP 192.168.2.2 and DHCP enabled. So, every computer here has 192.168.2.X IP number.
In the wireless router, there are few computers via LAN and others over wifi, getting IPs from main router in range 192.168.1.100 to 192.168.1.150
How can I do to make the computers to look each other.
Below is a image how network is connected.
Thanks in advance for your help.

On the Netgear router, add a static route for 192.168.2.0 Network and point it to the Windows Server NIC 1: 192.168.1.3
On the Windows Server, you will need to enable RRAS (Routing and Remote Access). Enable LAN Routing.
Here is a link for setting up LAN routing on 2016. Server 2012 should be similar.
