ER605: IPGroups & LAN>LAN Access Control Rules not possible?
With WiFi already part of the main LAN, I added a second network "OFFICE" to keep things like business NAS separate.
I assumed I could create an IPGROUP of my notebook and mobile devices that are on the main LAN WiFi, and allow these to access the OFFICE devices, while blocking other LAN users.
However, as far as I can tell, when defining LAN>LAN rules, I can only specify complete networks, not the IPGROUPS - which are only offered when selecting anything other than LAN>LAN.
Is there a viable option on the ER605 to permit only specific IPs to access across networks?
