I have VLAN11 and VLAN12.  VLAN11 is my production VLAN and VLAN12 is setup just for public wifi access and it cannot see VLAN11.  Now, I would like VLAN12 to be able to talk to just one of my printers on VLAN11.  How can I do this?

I have Cisco 3750 switches and an ASA 5510 firewall.  The ASA is providing DHCP to VLAN12 (the public wifi vlan).  There is  a sub-interface on the ASA that is on VLAN12.

Any help is appreciated!

Thanks.

Assuming both VLAN11 and VLAN12 are connected to the ASA, you need to create and access-list or add to an existing access-list an 'exception' that allows all of VLAN12 to access a single 'host' (i.e. printer) on VLAN11. Without seeing your ASA config, here is an example:

access-list my_access_list extended permit ip VLAN12 255.255.255.0 host printer1 255.255.255.255

Open in new window


Or if you need tighter restrictions, you'll have to look up necessary printer tcp port numbers an restrict to those.

So, would that ACL be on the ASA or the Switch?  And if on the ASA, would I do that on the Inside interface (VLAN11) or that sub-interface for the public wifi?

Thanks!

I never use ASDM; I rather prefer CLI as I gain much tighter control.

The access-list that allows access to your printer would be added to the sub-interface of your ASA - the interface that is connected to your WiFi VLAN.
