DHCP
IP DHCP addressing is supported in the Dot11Radio interface configured in universal client mode. The
following is an example of Dot11Radio configured with "ip address dhcp":
dot11 ssid test10
authentication open
!
interface Dot11Radio0/1/0
ip address dhcp
!
ssid test10
!
speed basic-1.0 basic-2.0 basic-5.5 6.0 9.0 basic-11.0 12.0 18.0 24.0 36.0 48.0 54.0
station-role non-root
Issuing a "show ip interface brief" will show the Virtual-Dot11Radio interface getting the IP address
from the DHCP server.

NAT (Network Address Translation):
NAT translation takes place if you overload the interface which has an ip address. In the case of universal
client, the virtual-interface has the ip address obtained from the DHCP. Hence we require to overload the
virtual interface to aid NAT translation.
Note NAT fails to translate with a DHCP address on the dot11 interface running in universal client mode.
The following configuration is supported on NAT:
ip nat inside source list 1 interface Virtual-Dot11Radio0 overload
The following is an example of a NAT configuration on a Cisco 1803 ISR:
C1803W_UC#
C1803W_UC#sh run
