I have a AP Netgear  proSafe NDAP350 . I have setup a internal wireless and it is working fine. I need to setup guest wireless to only access to the internet. There is a PIX firewall in the network. Any idea to how setup guest wireless to access to the internet only ?

What kind of switch is the AP connected to?

Also, do you have an available port on the PIX?

What you need to do is configure a second SSID for your guest network and configure a trunk port between the AP and Switch. Allow your internal wireless to trunk over your native VLAN (#1) and configure the second SSID to use a different VLAN (let's say #2.)

Terminate VLAN #2 at an available port on the PIX, configure the port with a security level of about 25... considering your LAN is security level 100 and DMZ is 50... configure IP, DHCP, NAT and firewall rules and you should be good. Guest SSID will only go out the internet and not into your network.

I will work on this project tomorrow. I don't know if the switch is smart or not? Can we do it if switch is not smart? Also what firewall rules do I need to configure on the PIX ?

Do I need to define DHCP on AP or PIX for Vlan 2 ?

As I know vlan 1 is untagged in AP now. I need to create a Vlan 2 and set as tagged  right ?

Access Point has only one port and it is connected to the wall jack port and it goes to the switch.  I am wondering if switch is not smart what we can do.

Please give me your idea?

Thank you

Some Netgear AP's have that function available and you just need to turn it on in the config.
I don't know if the model you mentioned has that or not but will check.

Sorry. I looked in the manual and don't see guest as a standard feature of that model.

Looks like a higher end AP, so Guest SSID will need to be manually configured.

You need a smart switch, at least one that will do trunking. Do you have an available port on the PIX, maybe it can do the trunking for you in some way...

How about your switch. Did you get a model number off it, and did you find out if its managed and can do trunking?

Could you please write the commands I need to configure PIX firewall for guest SSID ?

I'm a little rusty on my PIX, but it'll be something like this:

interface ethernet4 auto
nameif ethernet4 Guest security50

access-list GuestACL permit icmp any any echo-reply
access-list GuestACL permit icmp any any time-exceeded
ip address Guest

nat (Guest) 1 0 0

access-group GuestACL in interface Guest

Switch is not smart and also PIX doesn't have available port. I am wondering if we need to purchase another wirless router just for guest and  then setup the fireawall to route the wirless router to the internet only. Is that possible ? What is your idea ?

Just get a Smart switch that supports VLANs and 802.1q trunking and you'll be set.

Here's a good read on how to configure the VLANs on the 506,17005127
