I Have issue with Vlan on RouterBOARD 1100x4

• I Have added Vlan to the interface ether 5 ( VLAN ID 10)

• Added address 192.168.1.0/24 for ether 5 and 10.10.10.1/24 to Vlan Interface

• added separate masquerade for both networks with src address and out interface. (out interface is same)

My issue is if my computer(10.10.10.10/42) VLAN 10 interface it can communicate within Vlan (10.10.10.0/24) and also it can access Default vlan (192.168.1.0/24) how can I resolve this issue?

Lets see your config please as the explanation was not all that clear.

/export hide-sensitive file=anynameyouwish.

Also a network diagram will help understand the config and relationships between devices!
