Unable to access to the router web UI

[TheRiddler]

Hello, i've configured OPNsense in a VM inside a FreeNAS hardware, the WAN GW for OPNsense is the router.
I'm able to connect to FreeNAS and to OPNsense from the LAN client, and internet connection works fine for the network client, but i'm unable to conncect to the router GUI neither ping it. No new firewall rules are applied, at the moment only default rules.

The schema of connections is rappresented as below:

[router_GW 192.168.10.1]---[[OPNsense_VM 192.168.10.2] FreeNAS ]---[switch for LAN 192.168.10.0/24]

How can I access to the router web UI?

Thank you.

Do you have the same network range on LAN and beween OPNsense and your router?

Your diagram says so. If it is true, it is a bad idea. You should make a new network with a different subnet otherwise you will have problems with routing.

Example:
[router_GW 10.0.0.1/24]---[[OPNsense_VM 10.0.0.2/24] FreeNAS ]---[switch for LAN 192.168.10.0/24]

Than you should be able to access the router with 10.0.0.1. Check if your router has some rules that only allow access from local lan. Some products have this default configuration.
