Hi

 

Let me confirm your requirement. You set up a new VLAN and default routing on T3700G. You don't want other devices can access this new VLAN. If I have any misunderstand, please point out.

Generally, if you create a new VLAN and did not set up VLAN interface, then other devices cannot access this new VLAN unless they belong to this VLAN as well. If you create the VLAN interface at the same time, then the switch will has the inter-VLAN routing. It make different VLAN can access each other for unicast. You need to set up ACL to isolate the different VLAN.

@OKSSS, if you need to set several interfaces for VLANs (e.g. to reach the switch from inside of this VLANs), but don't want Inter-VLAN routing turned on, just disable routing:
