Different ip address

I have a client machine which ip address 192.168.5.xxx, and
server’s settings are: , and
both computers don’t let to change ip address from same ip range.

is it possible to connect from client to server computer?

You would need a router between the two to join the two subnets together.

This isn’t specific to Xibo - any IP based application would have the same requirements. You can’t communicate over a network if the devices are in different subnets, without a router to link them together.
