Hi All,

I have an ASA 5510 and a 3500 XL switch. I have a Linksys AP, no routing on it; I want to secure it so that only internet can be accessed and not the internal network. I have a dhcp server on the network, will I need the router to give ips or will i need to get a dhcp on the ap?

Hi Charlie,


I'm going to doubt that the Linksys supports multiple Vlans. If that AP is the only thing on that switch you may get away with setting up a seperate DMZ interface and then routing the traffic out the outside interface. If not, you may need to run the cable directly to the ASA.


You could either use the AP to dish out IP addresses. Or set up a separate DHCP pool on the ASA and make sure it serves just that interface. It really doesn't matter. Just make sure that the subnet matches and the default gateway is the IP you gave to the DMZ interface on the ASA.
