DHCP relay

  • Question
  • Updated 3 years ago
I have 9 AP’s in my hive.
I have an employee Wlan on vlan 1. The AP’s have a static IP in the subnet 172.25.40.0
I have set up a guest Wlan on vlan5. The guest lan DHCP has IP’s in the 192.168.10.0 subnet
1 AP is the DHCP server and this works fine. NAT in the firewall policy of the guest user is enabled and the AP gives out IP addresses and connects to the internet.
My problem is the DHCP relay configuration on the other 8 AP’s. I should get an icon showing that the AP is a relay, but I do not. What am I missing here?

Can you post screenshots of your DHCP server and DHCP relay configurations? What is the IP address of your AP acting as DHCP server?

Just to be clear: When you say you have enabled NAT in your firewall policy, this is inside your guests' user profile, not somewhere external on a 3rd party firewall device, right?

Thank You very much for answering. NAT in firewall is inside the guest user profile.

Sorry, I need to pass... I have never configured something this way.

I'd probably try to use the mgmt IP of the server within the relay config... but it's a wild guess.

I hope someone else can jump on here...

Hi there,

Taking a look at the screenshots you posted, this looks like a rather roundabout way of creating a separate 'VLAN' for a guest network without actually trunking the APs' switch ports. Is there any particular reason you've pursued this particular configuration?

Regarding your initial question of why you're not seeing the DHCP relay icon you'd expect, have you verified that the configuration object for the DHCP relay has been applied to those APs? You can do so from the Monitor tab by selecting the AP in question > Clicking modify > Service Settings > Navigating to the DHCP Server and Relay section. Ensure that the "DHCP_Relay" object you posted a screenshot of is in the right-hand column here, and that a complete configuration has been pushed to the APs in question.

Thanks and regards, 
Patrick M

Hi Patrick M. AS we are a relative new Company, and we occupy the same buildings after a management by out. The problem is that I do not have controll over the network switches yet. A configuration change is a very tedious process. I hope that a month or two into 2015 will change this.

I have done the following: Ensure that the "DHCP_Relay" object you posted a screenshot of is in the right-hand column here, and that a complete configuration has been pushed to the APs in question.

The AP does not show that it is a DHCP_Relay.

Kind Regards

Only access points configured as DHCP servers display a DHCP icon in the Monitor -> All Devices area.  Access points configured as DHCP relays do not.

Should there be a Relay icon?

Hey DT, I'm in a similar situation right now with a client and I was wondering what to enter for the Gateway address under the DHCP server options.  Did you specify 192.168.10.1?  Is there a physical device on your network that IP is assigned to?
