Way to access device on different subnet that is blocking connection

[andrea996]

Hi to all,
I'm deploying an OPNsense box with multiple vlan, the routing and firewall rules that I've created until now works but there is a single device that i cannot make function.
It's a Western digital nas My Cloud EX2 Ultra, is located on vlan 10 with IP 10.10.0.2, when I try to access it's web interface, SMB or NFS from an address inside vlan 10 there are no problem, but when i try to access the device from vlan 50 or any other vlan the device always answer "403 Forbidden", to make a test the firewall rule now is allowing any traffic from vlan 50 to vlan 10 so I don't think the problem is in the firewall.
My idea is that this device is blocking connection from outside it's network, so my questions are:
1) is my idea about the cause of the problem correct?
2) if the answer to 1 is yes, what is the best way to make this device reachable from a different vlan?

Thank to everyone

1) is appears so: https://community.wd.com/t/ex2-web-access-on-a-different-subnet/98814

2) it's already *reachable* - it's just denying you access. You might be able to kludge around it by applying NAT so access from other subnets appears to come from the firewall's interface on that VLAN

Thanks for your reply, with an outbound nat now the nas is working
