Help: ASA 5505, AP 1130AG, multiple SSID's and subnets

Hello all,

I have an ASA5505 between me and the internet (bridged off my ISP).  The outside interface gets the public IP from the ISP modem; all works great.

Off Ethernet0/6 on the ASA I have a Cisco Aironet 1130AG Access Point (power over ethernet).

My goal is to have two SSIDs, one as my main LAN subnet (zerone) and the other as a Guest 'net only (Zero G) that will only have access to the outside world, nothing on the inside.

It seems like I am almost there, but I'm missing something basic with Dot1q, trunking, or routing.

On my ASA I have Vlan8 as my "inside" with with a DHCPD scope enabled on inside.  I also have Vlan77 defined as my "guest-wlan" with with a DHCP scope enabled on guest-wlan.

On Ethernet0/6 (facing the AP), I have switchport trunk with allowed vlans 8,77 with 8 as the native.


This all seems like it should be working. I configured the AP as far as I know how and I can see both BSSID beacons. I am unable to connect to either. I am prompted for the WPA2 password, but time out after that.


Any ideas?


Attached are my Show Run of the ASA and AP.

Network is:  ISP_Modem <--> Eth0/0 ASA5505 Eth0/6 <--> Fe0 AP1130AG


Many thanks

HiCan you access your AP from


Can you access your AP from rest of your network  (ie from a subnet other than vlan 8) ? 

Also for a test, you can move a DHCP pool to your AP & see whether client gets connectivity.

Hi Rasika, thank you for

Hi Rasika, thank you for responding.

I can access the AP from my Desktop PC which is on Vlan8 ( I can access it via

The only other network I have locally is the guest-wlan Vlan77 (, which I have defined on the ASA as Vlan77 with IP I *cannot* ping this IP address from my Desktop PC (Vlan8).


As far as DHCP, while I can attempt this, would you agree that if I simply set a Static IP on my laptop's Wireless Interface, then joined the BSSID, this would provide the necessary results?

Right now I believe the problem is routing/tags.  Hopefully DHCP broadcasts will start working once the routing is working.


If you agree, I will attempt the Static method as described above.


Thanks again for the assistance

To add to my troubleshooting

To add to my troubleshooting:

I just created a capture on the ASA on the "guest-wlan" interface.  
I then created BVI77 on the AP with IP address
From the ASA, I then tried to Ping the new BVI out the guest-wlan interface.

It looks like the ASA is arp'ing for the address, but not getting any replies. I feel this is the right step, but now I'm stuck at the AP.  


asa# capture test interface guest-wlan
asa# ping guest-wlan
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to, timeout is 2 seconds:
Success rate is 0 percent (0/5)



asa# sh capture test
