Why doesn't the computer on the network at the other end of the GRE tunnel ping?

Question

Cisco Packet Tracer

I made such a simple network topology in Cisco Packet Tracer

Between router A and B, a GRE tunnel is configured (192.168.2.1/30 - 192.168.2.2/30)
When you try to ping the tunnel from router A (ping 192.168.2.2), everything works, as in in the opposite direction, but if I try to ping the server on the other end of the GRE tunnel from a computer, I get a wait timeout..

What could be the problem?
If something I wrote is not clear, then please point out the mistake, I will correct it.

Answer 1

It is necessary to configure a static route to the server ip or subnet via gre tunnel:
RouterA(config)#ip route 192.168.2.2
