Gemfire client timeout

We are trying to access an entry in client by accessing region "UserToken" thru spring configuration.

We have the "read-timeout" property set to 3 secs as seen above.

On the server side, we use a firewall to drop all requests coming from client side.

When we try to access entry in "UserToken" region on the client side, we expect it to timeout after 3 secs. However, we see that it times out after 120secs.

Question is, are we using right configuration "read-timeout" for the desired result? Is there any other solution for this problem?

Thanks,
