Access Lists

I want to prevent a vlan on the switch from being able to talk to other vlans, below is what I thought was the solution, but it denies traffic to all. I want to deny to all apart from one vlan (


ip access-list extended "101"
     10 permit ip
     20 deny ip



vlan 207
   name "Test"
   ip access-group "101" out
   ip address
