Opnsense in different subnet

[Ashwini]

Opnsense and server is installed in vmware of host machine with bridge network.

My opensense and server is in same subnet. But the existing router is in different subnet.
Current behaviour: other machines which are in same subnet as opense and server are able to connect to existing router.
Even the server is able to communicate with existing router when opensense is down.

And the opnsense host machine is able to communicate with router.

But opensense is not able to connect to router IP. Please let us know what is the configuration needed in opnsense so as to make it communicate with route ip?

Please refer the attached image.

Is "192.168.*.*" in your diagram the same subnet?
Have you set up a gateway for the OPNsense?
