Question : VLAN support for ASA 5505

I am looking to set up a wireless network for someone. I will be setting up some access points with 2 SSIDs one for a public network and another for a private. I am looking at an ASA 5505 to be used as the firewall/router. I once used one with the basic package and I know that it is limited to 3 VLANs but the third VLAN is limited to only contacting one of the other VLANs.

Now I would think that this would mean that it will work for my application. I only need the public wireless VLAN to contact the outside interface, and then the private VLAN will be able to access the outside interface as well. Does this sound correct?

Answer : VLAN support for ASA 5505

yes this will work with a basic license. You will have a no forward.

Attach is part of the code for an ASA and the code for a Cisco 521 AP
