I know that VLAN maps have no bidirection. Is there any other way to do bidirection access-list between VLAN?
The goal scenario:
Host A on VLAN 2, host B on VLAN 3. Host A should be able to open port on host B, but host B should not be able to open port on host A.
Anyone can help?

Hi,
if there is a routing device between the 2 VLANs, then I think you can use ip access-lists to filter the traffic beetwen the 2 VLANs

Hi Mark,
Thanks for you reply.
The routing device is the 3560 itself. I enable ip routing and the VLAN interfaces is directly connected due to at the same device. I had try to use ip access-list to VLAN interface, it seems didn't work.

rp,
in config:
ip access-list 101 deny tcp host b host a
ip access-list 101 permit ip any any
interface vlan 3
ip access-group 101 in
There are lots of other ways. This is just an example.
