Cisco Aironet 1250 VLANs ?

[xilvar]

I've never done any configuring of IOS based equipment before, but the growth of our team forced us to buy a real wifi ap a few months ago.

I set it up originally with no specific vlan's and two SSID's The original intention being to broadcast a public ssid and not broadcast the internal one. Both were configured to run WPA2 personal PSK.

Tonight I finally got around to configuring two vlan's and assigning the ssid's to them because I want to broadcast both ssid's now. The 'internal' vlan is 'native' and goes through just fine to our firewall and router.

The second vlan 'guest' is not allowed to be native (which makes sense) but I also can't figure out how to get it to be able to access the outside network. I'm able to connect just fine to the ssid assigned to it, but don't get any access to anything.

Clearly the router is capable of allowing two ssid's access to the network since it was happy to do so before I made the vlan's, but I don't know how to make it do it...

Anyone have any ideas? Bear in mind that I have almost NO other network equipment... (no cisco catalysts or anything like that...)

First off, what's at the other end of the Ethernet cable coming out of the Aironet? I assume a switch of some kind. In order to use VLANs, you need to configure the switch port to do trunking. The other data is working because it's being tagged as native, but it seems that nothing else on your network knows what to do with the VLAN tagging.

(Note -- this is an educated guess based on this people often do, and my description is a bit oversimplified for the purpose of helping you fix your problem.)

The other end of the aironet is connected to an unmanaged netgear switch (jgs-524) it happened to be the cheapest 10/100/1000 switch I could find at the same site I bought the aironet from. I don't think it supports VLAN though.

Between the netgear and our dsl router is a linksys wrt54g running an opensource firmware (tomato). That does dhcp/nat for both wired and wireless clients, and L7 QOS for traffic that goes out to or comes in from the dsl.

I'm guessing that I won't be able to get my setup working unless I get a managed switch?

Is there any another way of achieving what I wanted? two SSIDs broadcasting with both connected to the native network? the vlan doesn't matter THAT much since all our actual traffic is ssh...

Thanks for all your help btw!!

I've never messed with VLANs on a Linksys, I know tomato does a lot but not sure about VLANs. Hopefully someone will chime in who's done it before.
