Hello.
There is a connectivity problem between two subnets.
LAN1 192.168.0.0/22 where the server with OPNsense 192.168.1.21 is specified as the gateway
OPNsense is connected to three networks:
to network 192.168.0.0/22 via interface 192.168.1.21
to network 192.168.5.0/24 via interface 192.168.5.21
to the Internet via WAN1 interface
LAN2 192.168.8.0/22 with Router 192.168.8.1 specified as gateway
Router is connected to three networks:
to network 192.168.8.0/22 via interface 192.168.8.1
to network 192.168.5.0/24 via interface 192.168.5.1
to the Internet via WAN2 interface
Router and OPNsense are both connected to the network 192.168.5.0/24 and through the interfaces 192.168.5.1 and 192.168.5.21 respectively, and can see and ping each other without any problems.
OPNsense has a static route to the 192.168.8.0/22 network through the 192.168.5.1 Router and can see and ping computers in the 192.168.8.0/22 network without problems.
There is no access to setup or configuration of the 192.168.5.1 Router or any computers in the 192.168.8.0/22 network.
How can I make computers from the 192.168.0.0/22 network see and ping computers in the 192.168.8.0/22 network?
UPD: I forgot to mention that if you specify the subnet 192.168.5.0/24 on ANY device with the gateway 192.168.5.1, then this device will able to see and ping the subnet 192.168.8.0/22 without problems
Please help.
I have attached a network diagram.

you are missing the 2nd half of your problem. you need a static route on the other router for the LAN1 network.

yeah. cant do that. Router isnt accessible for any changes.

your traffic gets there, but no route to get back. ;)

Then you need to NAT. Without a route in the upstream router you simply cannot use any additional subnets. Matter of fact.
