Wireless Access

Can i have the command to check the default gateway of the client connected to an iap

I have the access to the ap where the client is connected to. Can i  check the gateway of the client through the ap it is connected to

Also can i check the type of Vpn ( local , distributed l2 , l3 etc)  used between my iap and controller through any command

Have you seen this command?  http://www.arubanetworks.com/techdocs/Instant_423_WebHelp/InstantWebHelp.htm#CLI_commands/showvpndialer.htm?Highlight=vpn

That Reference was of great help.But still i am not able to figure out if my network has a local VPN or distributed l2 type vpn .Any more specific command which can help to figure this out 

Okay figured that out my running config has the below:

(Instant AP)(config)# ip dhcp <profile-name>

(Instant AP)(DHCP Profile <profile-name>)# server-type <local>

(Instant AP)(DHCP Profile <profile-name>)# server-vlan <vlan-ID>

(Instant AP)(DHCP Profile <profile-name>)# subnet <IP-address>

(Instant AP)(DHCP Profile <profile-name>)# subnet-mask <subnet-mask>

(Instant AP)(DHCP Profile <profile-name>)# dns-server <name>

(Instant AP)(DHCP Profile <profile-name>)# domain-name <domain-name>

(Instant AP)(DHCP Profile <profile-name>)# lease-time <seconds>

(Instant AP)(DHCP Profile <profile-name>)# option <type> <value>

(Instant AP)(DHCP Profile <profile-name>)# end

So figured out , that my network is in local vpn between iap and controller.Thanks again

It is not straightforward.  Routing and DHCP decide the flow of traffic.
