I have a router-on-a-stick that is connected to a switch to 3 workstations that are one connected to VLAN 2 & VLAN 3. 2 workstations are connected to VLAN2 while the other one is connected to VLAN3. Now the problem is that i need to deny network traffic frm workstations that are connected on VLAN2 to VLAN3. But i cant seem to do that even tho i tried using standard ACL or extended ACL. Any1 can help??
