Cisco Wireless :: WLC 4402 Guest Network DHCP Run Out Of IPs?

Aug 26, 2012

I have this guest wlan working with web authentication, as you may know in order to get authenticated you must have an IP address first then have a valid username and password. The problem is that if you don't have valid credentials you keep the IP address anyways.I'd like to know if there is a way to release the IPs that are not being used? The WLC is the DHCP server for this network.

Cisco :: 4402 - Sluggish DHCP For Guest Users

Feb 3, 2011

Our Guest access system seems to be having problems with DHCP. It seems to take a while to deliver an IP address making the client device show the "limited or no connectivity" message, which of course makes the users complain. On one occassion I have seen my own client eventually picking up an address even after the limited connectivity message appeared. On another I saw the debug showing "Dhcp request for autoconfig address", which I suspect is a symptom of the problem.
 
Our Anchor Controller is the DHCP server and is a 4402 running 7.0.98.0 - I've attached some DHCP packet debug.

Cisco :: WLC 4402 - Guest Network Access

Mar 23, 2011

We have a 4402 wlc setup for guest network access. We are using the local net users to provide access to our guests. We have an issue where if a user signs in through the web, sometimes but not always, they are then forced to keep signing back in almost every 30-60 seconds.

Cisco Wireless :: 1042n AP Can't Get DHCP For Guest Network

Aug 6, 2012

This is rattling my brain. I have configured 2 SSIDs, one for internal, one for guests. They are on seperate VLANs (50 and 51) and bridge groups (1 and 2). I can get IPs via DHCP for the internal network, but not for the guest. I can't get DHCP for any VLAN 51 sub-interface, nor clients that connect to it. The overall goal is to keep all traffic on the guest network seperate from the internal traffic, however, DHCP requests will be from an internal server. I have removed all the access-lists for troubleshooting purposes. AP and Switchport configs are below!

Current configuration : 4011 bytes

Cisco :: 4402 WLC Guest Wireless Setup

Jul 24, 2012

I am trying to setup a Wireless Network on my WLC that is totaly independent of our internal LAN. Port1 is designated at the .14.0 network and Port2 is the .18.0 network. The 14 network (Port1) will be the guest and 18 network (Port2) the internal wireless.
 
The issue i am having is nothing is routing to Port1. I have the Guest Wireless set to get DHCP from the WLC and i can get an address but i cant get internet access. I tried configuring a Network Route but it will only let me set the service port as the Gateway and not the IP for Port1.
 
I am running software version 5.1.151.0 and using this guide as it is the only one i can find. [URL]
 
Here is a screen shot of my Interface config.

Linksys Wireless Router :: E4200v1 Get A List Of DHCP Clients On Guest Network

Jul 3, 2012

I've got an E4200v1 running 1.0.04 firmware with guest access enabled. I'd like to find out who is logged in using the guest access. Is there a way to get a list of the DHCP clients on the guest network? I'm able to do this for the non-guest access via the WEB interface's Status->Local Network->DHCP Clients Table page. But I can't find a similar table for the guest network.

Cisco Wireless :: 4402 - Guest Access No Longer Working

Aug 10, 2011

There is one guest interface, one guest WLAN. The WLAN is set with a DHCP override address of the guest interface. But it no longer allows this as I found out. Anyway, I can get the client to now receive an address from the internal pool on the WLC, but it will not route to the authentication page. I noticed that the WLC excludes the clients attempting to connect on the guest WLAN due to failed 802.1x authentication! the WLC never even gave me the chance to authenticate using an account created either through the lobby ambassador or creating one directly on the controller.

Cisco Wireless :: 4402 Guest Anchor Controller 5508 Software 7.2

Nov 6, 2012

We currently have all of our foreign AP controllers on software version 7.0.116.  This consists of a mixture of 4400 and 5508 WLC's.  Our guest anchor is a 4402 on version 7.0.116.  We are replacing the guest anchor with a 5508.  We are also upgrading our 5508 wireless controllers to version 7.2 to support the 3600 series AP's.  My question is what is the recommeded code that the anchor controller should be on?  Should it also be upgraded to 7.2?  If we upgrade the anchor controller to version 7.2, will this affect anchoring to 4400 series foreign controllers still on7.0.116?

Cisco Wireless :: 4402 - No Internal Interface / How To Get Guest Access Working

Nov 29, 2011

I have been trying to create a Guest WLan on my 4402 WLC system and have found several confilcting documents explaining the procedure. During this process I have notices that although the current corp wireless works, there was never a virtual interface created for it. Instead it uses the same Wlan/Vlan as the ap manager and managemnt interfaces. Could this by why I cant seem to get the Guest access working? or is this not a problem after all since the wireless does work.

N600 - Set DHCP Server On Guest Network?

Mar 6, 2012

So have a wireless guest network on an N600 router. Here is my setup:

pf sense -> untangle -> switch <- N600

the N600 is just an access point and does no DHCP. The primary wireless network gets IP no problem but the guests are not getting an IP. I'm assuming the N600 has no way of issuing an IP on the guest network. how to set a DHCP server on the guest network and have a static route to the pfsense firewall from that network.

Cisco Wireless :: DHCP Server Override On 4402 WLC

Apr 17, 2012

I have successfully implemented wireless guest access using 4402 WLC as the Anchor and 5508 as Foreign. The Anchor controller also provides dhcp services to guest clients. The 5508 is LAGged and there is no issue with the guests traffic separated from corporate. At a remote site, there is a 4402 WLC using LAG and also acting as a Foreign controller. But when a client connects to the guest WLAN, it obtains a corporate dhcp address instead of the dhcp address assigned from the Anchor controller. The guest WLAN setting is the same as with the 5508 controller i.e. DHCP server override is ticked and the management IP address of the Anchor controller is specfied. Also DHCP Addr required is ticked. Why the 4400 controller is not forwarding dhcp requests to the anchor controller and instead sending to the corporate dhcp server.

Cisco Wireless :: 4402 / Clients Not Getting DHCP From External Server?

Jan 16, 2013

I have a 4402 (version 7.0.235) working with 10 units of 1121 APs connected to it. The WLC is not configured to work in LAG mode. Physical portt #1 is connected to the Main Switch (trunk). I have 3 WLAN mapped to 3 Different VLAN and Everything (security and internal, external DHCP) is working swell...Now- I have connected Physical port #2 directly to an ADSL Router (giga port), Configured Port 2 as untaggedwith the proper IP details.I have configured this interface to receive DHCP from the ADSL Router and for some reason, Clients are not getting addresses.When I assign a Static address to my laptop I get internet access and all is nice. I tried configuring The WLC internal DHCP server (instead of the ADSL router) and that didn't work. It seems like a DHCP problem but I dont understand the source of the problem of think of the solution.When turning off the proxy settings I noticed that it worked. Is there anything to do with that? The problem was that after a while the other WLANs starting causing DHCP issues as well.

Cisco Wireless :: Internal DHCP Server On 4402 Controller

Apr 8, 2008

I am trying to setup a guest vlan. I set up an interface for the guest vlan on my 4402 controller. I assigned the guest vlan interface an IP of 192.168.2.10 with a 24 bit subnet mask.
 
This vlan will go to my DMZ where there is no DHCP server so I need to setup the internal DHCP server. I created a new scope but I'm having trouble with what to put in the Network field for the DHCP scope. The pool addresses are 192.168.2.100-200. with a 24 bit subnet mask.
 
Every time I try to apply the configuration I get an "error in  setting DHCP scope network and netmask".
 
I've tried using:
 
192.168.2.10
192.168.2.255
192.168.2.254
 
as entries for the Network setting but no go. The docs say to enter the IP address used by the management interface with subnet mask applied.
 
I was assuming they meant the interface for the guest vlan.

Cisco Wireless :: WLC 5508 / Guest VLAN Unable To Get DHCP IP Address From Anchor Controller

Feb 23, 2012

In our test set up, we have two WLC 5508 Controllers connected via Checkpoint UTM-1 firewall Inside and DMZ Interfaces. Both the WLC controllers are connected to the firewall via Cisco 3750 switch. On the Local (Inside) Controller, guest SSID is enabled and attached to the wireless management Interface. On the remote anchor controller, guest SSID is enabled and attached to the Management Interface as well. The following configs are replicated on both the Controllers.
 
SSID Name - guest
Interface - Management ( VLAN 10 on Local and VLAN 20 on remote) -
Mobility Group: Same configs at both ends
SSID Anchor : Anchor SSID on local and local SSID on Anchor.
AP: CAPWAP 3502 Management Subnet

[code]....

Is there any thing missing in the wireless configs and or the firewall rules as i could not see DHCP request back from the Anchor Controller. Also, after DHCP is obtained, the web authentication request will be redirected to an Amigopod device for authentication. In this case is the redirect URL congiguration to be performed only on the Anchor Controller or is this to be replicated on both the Local and Anchor Controllers.

Cisco Wireless :: 4402 WLC - Get Network For Guests Instead Of DMZ

Nov 4, 2012

we have a two port 4402 WLC here with only one port currently in use. The topology is bacically the used port uplinks to a dmz switch. Our Intranet and the Internet are accessed via an ASA from the WLC. The WLC also sits in the DMZ. This WLC is only used for guest wireless access. The AP information and traffic is exchagned from a primary WLC on our Intranet and authentication is done via RADIUS.  Internet access is handled through the ASA as well on the DMZ. We have a completely independent ISP broadband connection here that was put in long before I was ever here and is used for guest wired web access. All ports are clearly labelled and have bright pink patch cords. What I would like to do is have our wireless guests be on that network rather than our dmz for their web access. I have pulled an ethernet cable from the switch that connects to that broadband connection to the cabinet with the 4402.  So the physical is fine right now. I'm not all that familiar with the WLC's, so I'm not sure if everything else can remain the same as it is right now, but just connect the second port to the broadband connection and route guest Internet traffic through there rather than the DMZ.

Home Network :: Cisco Linksys E1500 - Wireless Security Protocol For Guest Network?

Oct 29, 2012

Having an issue with a Cisco Linksys E1500 on a home network. The device has a feature to provide a guest wireless network but the guest network can't get to the internet. A wired connection is fine, as is the normal wireless network but not the guest. The cheesy thing is, that it doesn't list an option for what type of wireless security protocol you want on the guest network. I'm assuming that it uses the same security protocol that the normal wireless network uses, but who knowsEspecially weird is that it asks you what password you want on the guest network but then the guest network show to be insecure when you try to connectthought maybe it was something funky with some of my configurations so I went ahead and factory defaulted it and just set it up with an insecure network for both the normal and guest networks. This didn't solve it. The guest network still couldn't get to the internet. In fact, the guest network can't even ping the router.

Cisco :: 5508 - DHCP Load Sharing With Redundant Guest Anchor Controllers

Jan 28, 2012

I have 2 x Redundant Guest Anchor Controllers (5508) located in 2 separate Data Centers with all the management and guest user VLAN spanned between two. Everything is working fine with the Guest WiFi access except the DHCP functionality as the Controllers are acting themselves as the internal DHCP Servers.
 
This is how I tried to distribute : 
network. 10.1.0.0/23
gateway: 10.1.1.254 
Controller 1, DHCP Server pool: 10.1.0.2 - 10.1.0.254 Gw: 10.1.1.254
Controller 2, DHCP Server pool: 10.1.1.2 - 10.1.1.254 Gw: 10.1.1.254
 
As the user load balancing between the Anchor Controllers cannot be controlled (i.e. they are active/active), the same client sometime getting 2 different IP addresses from both the Controllers (as they do not talk to each other in terms of DHCP) hence depleting the pool addresses.
 
I guess one way of solving this is to just run 1 DHCP server in one of the controllers but that defeats the purpose of having N+1 Controllers. Is there a better way of doing the DHCP load balancing and having full redundancy at the same time?
