Station is not receiving an IP address from DHCP

Hello guys,

I have an ASA 5505 functioning as a router to connect to the Internet. Also, it is my DHCP server for my clients, and APs. When I connect my laptop to the ASA, I get an IP address and able to configure my WLC. The APs also receives an IP address from the ASA. However, when I connect to the AP wirelessly as a wireless client, my laptop is not receiving an IP address from the DHCP which is my ASA.

Here is my topology:

[3602i]--------[ASA5505]--------[WLC2504]

Here is my ASA config for my clients:

!

interface Vlan12

description *** DEFAULT GATEWAY FOR Wi-Fi GUESTS

nameif GUESTS-if

security-level 100

ip address 10.2.12.1 255.255.255.0

!

dhcpd address 10.2.12.100-10.2.12.131 GUESTS-if

dhcpd dns 208.67.222.222 208.67.220.220 interface GUESTS-if

dhcpd lease 1048575 interface GUESTS-if

dhcpd option 3 ip 10.2.12.1 interface GUESTS-if

dhcpd enable GUESTS-if

!

Here is the WLC interface config:

Re:Station is not receiving an IP address from DHCP

So ASAs will not work with DHCP proxy enabled. Disable DHCP proxy and you should get an address.

Re: Re:Station is not receiving an IP address from DHCP

Hello jsnyder81,

I have another question. This is still related to the same network.

I am able to connect to the wireless network now, and receiving IP address from the ASA 5505; however, I can only ping my wireless gateway. I also don't have access to the Internet.

When I hard wired my laptop to the ASA's switch port, I am able to browse the Internet, but not via WiFi.

Here is the routing table that I have on the ASA:

Gateway of last resort is 192.168.1.1 to network 0.0.0.0

C    10.2.8.0 255.255.255.0 is directly connected, PRINTERS-if

C    10.2.9.0 255.255.255.0 is directly connected, FIOS-if

C    10.2.10.0 255.255.255.0 is directly connected, IP-CAMERAS-if

C    10.2.11.0 255.255.255.0 is directly connected, WiFi-USERS-if

C    10.2.12.0 255.255.255.0 is directly connected, GUESTS-if

C    10.2.13.0 255.255.255.0 is directly connected, WIRED-if

C    10.2.3.0 255.255.255.0 is directly connected, EXSi-if

C    10.2.4.0 255.255.255.0 is directly connected, AD/NPS/CA-if

C    10.2.5.0 255.255.255.0 is directly connected, inside

C    10.2.6.0 255.255.255.0 is directly connected, WLC-if

C    10.2.7.0 255.255.255.0 is directly connected, AP-if

C    10.2.20.0 255.255.255.0 is directly connected, WIRELESS-PILOT-if

C    10.2.21.0 255.255.255.0 is directly connected, WIRED-PILOT-if

C    10.2.22.0 255.255.255.0 is directly connected, SERVERS-PILOT-if

C    192.168.1.0 255.255.255.0 is directly connected, outside

d*   0.0.0.0 0.0.0.0 [1/0] via 192.168.1.1, outside

I also have this command:

same-security-traffic permit inter-interface

Re: Station is not receiving an IP address from DHCP

Do you have a NAT overload setup to NAT out for the the wireless subnet?

Thanks for the quick reply.

I have NAT enable, but configured wrong IP on my dhcpd option 3. Thanks for pointing it to me. I was able to fix the incorrect IP address.
