Mycloud not reachable without masquerading from other subnet

Hello there,

recently I changed my network layout at home and put my ex4100 with other devices in an vlan wich is specificly only for storage devices. All devices of other vlans can reach it via smb protocol, but if I have no masquerading enabled in my firewall, I’m not able to access the webinterface.

Does anyone now, if there is a setting, that allows the access from another subnet?

Best regards,
