The Inter-VLAN routing option means it will allow/disallow (checked/unchecked) the communication of the devices on that particular VLAN to other VLANs.
If you need the devices in VLAN1 access devices in VLAN2 & VLAN3 but not the other way round, then it is recommended to use the Internal Network Firewall Rules for advanced control the access between VLANs.
