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.

Hardware 1- Opnsense host
Hardware 2 - Server
Hardware 3 - Client

HW 1,2,3 are in same network.
Internet access is given only for HW2(server).

HW3(Client) can access HW2(Server).

HW1 ( opnsense ) will act as a firewall/router between HW2 and HW3.

My question is how to protect HW3(client) in case of external attack to HW2(server) using security features of HW1(opnsense).

Hi,

I am new to Opnsense.
Is it mandatory to have internet connection to use security feature of Opnsense?
I see there is a "Download and Update" option in IPS for installing few rules.
My question is can i download all rules and update at once and use it later without internet.
Will my Opnsense work perfectly without internet after updating once?

thanks in advance
