Guest Wireless and VLans

Jump to solution

I am trying to add a Guest Wireless network on top of our current infrastructure.

I have created VLAN 11 for the guest traffic.

APs are configured with the guest SSID on VLAN 11.

The firewall is configured with a Guest Wireless interface that is configured as a DHCP server and is on VLAN 11.

VLAN 11 has been configured on all switches (NetVanta 1234 POE and 1238 POE) with the port that connects to the firewall configured to VLAN 11.

The APs are connected to ports configured as Trunks.

The basic structure is:

AP connect to switchport configured as trunk on 1 NetVanta 1234.

This is trunked via gigabit port to a NetVanta 1238.

The firewall is connected to a 2nd NetVanta 1234 on a switchport configured to VLAN 11.

The 2nd NetVanta is also trunked via gigabit port to the NetVanta 1238.

AP -> 1st 1234 -> 1238 -> 2nd 1234 -> Firewall

I cannot get a DHCP address on the guest network. Cisco has verified my firewall configuration is correct. Can anyone see why my VLAN 11 traffic may not be passing through?

I have, one at a time, taken each device out of the loop until I hooked directly to the firewall. I still did not get an address. It appears that the firewall configuration is the issue.

Thanks for taking the time to look at this.

Thank you for asking this question in the support community.  There is a post that addresses a very similar question:  https://supportforums.adtran.com/message/5461#5461.  However, if you would like to reply with the configuration of the ADTRAN wireless controller, (please remember to remove any information that is sensitive to the organization), I will be happy to review it for you.

levi,

     Thanks for your reply. We do not have an Adtran wireless controller, only Adtran switches. The APs and Firewall are Cisco.

As long as the VLANs are defined properly on all the ADTRAN switches, and the APs are correctly tagging the "guest" VLAN on the trunk ports, then the ADTRAN switches should just pass them through.

If you connect a PC to a port in VLAN 11 on the "2nd 1234" does it obtain an IP address from the firewall?  What if you plug a PC into the "1st 1234" on VLAN 11, does it obtain an IP address from the firewall?
