Is NAT allowed between the Access Point and WLAN Controller?

Suppose that the AP and Controller communicate over a L3 network.
Can NAT be performed in between?
For example, suppose that the AP is connected to an ADSL router that performs NAT.

Just to expand on what George had said, when the controller sends the discovery response to an AP the controller's ap-manager interface IP address is embedded in the response.  So if this packet gets NATed the embedded address won't.  So just make sure they AP can route packets to whatever address is configured on the controller.  The controller doesn't need to see the AP's configured address, this one could be NATed.

    How to delete the line between the last point and first point? 
    I want to draw a curve many times, from first point to the end point. and redraw from first point to the end point.But I hope update point by point. but between the end point and the first point,  there is a line. How to delete the line?
    the code is:
    CNiReal64Vector plotData(50);
    m_graph.ChartLength = 50;
    //m_graph.ClearData();
    for (int j = 0; j < 2; j++)

    Hi Kumar,
    I think you can just delete it in the sales order directly, if you are using make-to-order scenario, then there will be special stock left for the sales order as the production has been goods receipt, you need to use MM transaction move the stock to unrestricted use stock. If you are using make-to-stock scenario, there should be no further problem. If you are using assembly order, please try to reject the sales order item to see if it could fullfill your requirement.

  • Connection between lightweight access point and switch?

    Hello everybody,
    I am a bit confused about cisco 1000 series access point connection. On wireless lan controller and lightweight access point basic configuration example document id 69719 (http://www.cisco.com/en/US/products/ps6366/products_configuration_example09186a0080665cdf.shtml), I understood the access point has two vlans associated with (vlan 3 and 4). Am I correct?
    Why is connection between access point and catalyst port just access port rather 802.1q trunk? How vlan traffic can traverse from the access point to controller?
    Please advice.
    Many thanks,
    Nitass

    Nitass,
    The AP itself does not need to be a trunked port, but the uplink to the controller does. When using a Lightweight enviroment, all the traffic passes thru an encrypted LWAPP tunnel from the AP to the controller, and then gets sent out the correct VLAN interface on the controller.

  • Connection between the test agent and test controller randomly drops.

    Hi all,
    I setup a test environment with the VS2013 IDE, test controllers, and test agents all on the same domain and I am experiencing random connection drops during test runs.
    I am able to get a connection started between the controller and agents, but have not been able to get a stable enough connection to run a test suite of 3000+ tests. 
    I have added firewall exceptions for the default ports and turned to disabling the firewall on both the controller and the agents.
    I installed and configured the controller/agents with the same admin account.
    This account is in the TeamTestAgentService, TeamTestControllerAdmins, and TeamTestControllerUsers groups of the controller machine.
    I am using Windows Server 2012 for the controller, and Windows 8.1 for the agents.
    Here are the agent logs right before failure:

    Hi,
    To run automated test using MTM, there is at least one lab environment with at least agent one machine.
    It is easy to configure standard lab environment than SCVMM lab environment.
    I suggest that you could refer to this article below to configure lab environment and do tests.

  • Communication between : AP and WLAN controller

    Hi,
    The communication between AP and WLAN Controller is ( Data and Control ) UDP.
    Source port 1024 and destination port 12222 and 12223. Actually which device listen to which port or both should listen as control and data can be generated from both the devices.
    How does the user ( wireless client) traffic is switched - if user traffic is a TCP traffic. It will be sent to WLANC and then WLANC forwards it to respective VLAN or default gateway ( depending upon the destination in the packet ).
    Please explain / share the experience.
    any link on cisco.com
    Thanka in advance
    Subodh

    "the LWAPP Control and Data messages are encapsulated in UDP packets that are carried over the IP network. The only requirement is established IP connectivity between the access points and the WLC. The LWAPP tunnel uses the access point's IP address and the WLC's AP Manager interface IP address as endpoints. The AP Manager interface is explained in further detail in the
    implementation section. On the access point side, both LWAPP Control and Data messages use an ephemeral port that is derived from a hash of the access point MAC address as the UDP port. On the WLC side, LWAPP Data messages always use UDP port 12222. On the WLC side, LWAPP Control messages always use UDP port 12223.
    The mechanics and sequencing of Layer 3 LWAPP are similar to Layer 2 LWAPP except that the packets are carried in UDP packets instead of being encapsulated in Ethernet frames."

    I can connect to the access point and it shows that I an connected to the internet.  However when I open a bowser it says page cannot be displayed!  Signal is very good to excellent.  Also, I have been using it all day and it was working fine, until I shutdown.  When I booted back up it stopped working.  The internet is working!  I have XBOX Live working right now.  Just not the computer.  Any Help would be appreciated.

    Hi... it seems that your Wireless adapter on does get a IP address or DNS no after reboot. Try assigning a Static IP address and DNS on the Wireless Adapter. Also try to update the drivers for that wireless adapter.

  • IOS 6, Netgear access point and Internet

    Hi,
    I’ve reached a point where I’m not entirely sure what to do next.
    Here are some quick details (all are on most recent firmware unless stated):
    Router: Draytek Vigor2830n
    Access Point: Netgear WG102
    Devices: iPhone 4, iPhone 5, iPad 2 and two iPad 2’s for comparison on iOS 5.
    So, all devices running iOS 6.1.3/4 will connect to the Netgear access point just fine, can browse the LAN / stream media from network shares but internet access seems to be 'delayed' and can take anywhere between a minute to 20 minutes to connect (I give up after this). In comparison both the iPad 2’s running iOS 5 will gain internet access immediately after connecting to the access point.
    On the other hand, when connecting to the routers wireless on all devices it works flawlessly and internet connection is 'instant'.
    Given the problems that Netgear wifi has had with iOS 6, which were supposedly ‘fixed’ in iOS 6.1, I’m not sure what to do. It’s definitely a software problem, and could well be something to do with the router (along with connecting to the access point and iOS 6), but I’m not sure what to start changing first. iOS 5 works fine, so what has changed in iOS 6 to break it?
    Its not a security issue like before 6.1 and not being able to connect to the access point at all.
    Basically:
    - I either need to figure what in iOS 6 is causing this ‘delay’ and how to fix it
    -Give up on the access point and buy a new one (seems a bit extreme given that every other devices works fine – iOS 5, blackberry, laptops etc).
    -Wait for iOS 7, hopefully in the next couple of weeks and see if it fixes it, though I can find little information on this issue as it is, and nothing to suggest iOS 7 might help. Though if iOS 5 is fine, iOS 6 broke it and 6.1 slightly fixed it, maybe iOS 7 will cure it? Doubt it…but worth waiting a few days.
    Anyone got any suggestions? I have been through all the usual (HTTP proxy, forget this network, reset network settings), nothing makes it work flawlessly like iOS 5 and the issue is the same on a wide spread of devices running iOS 6.

  • The connection between your access point, router, or cable modem and the Internet is broken.

    At random points throughout my laptop usage, I randomly disconnect from the internet and receive these 2 messages:
    1. The connection between your access point, router, or cable modem and the Internet is broken.
    2. The default gateway is not available.
    It fixes the issue for a short period of time, but constantly happens. This is really starting to annoy me. I have no problems on any other internet, and other people i live with are connected with no issues to the internet. I have tried a number of solutions
    online that has "worked" for others to no success such as resetting the router, fooling around with command prompt, and changing the performance settings to not drop internet when low on power. Does anyone have a solution for my technical problems?
    I am running Windows 8.1 on a Lenovo ideapad that is less than a year old. I will be honest I am not a very knowledgeable person when it comes to computers, so please use simplified explanations.

    Checked this ?

  • HT203167 most of my music has the exclamation point and won't allow me to place songs in a playlist on a new ipod...why?                                     ?

    Most of the songs in my iTunes library has been tagged with the exclamation point and will not allow me to place those songs on a new Nano iPod I bought...why?  This is music I have purchased in the past.

    See here: iTunes displays a -69 error when syncing iPod
    You can use the disk diagnostic tool built into the iPod's firmware to test the health of it's Hard Drive.  See this post from another forum member turingtest2 on how to do this as well as what the resulting numbers mean.

  • I have a Canon MX882 and more often than note get an error message saying the printer is not connected. I check the printer and the get the message that the access point is accessed. I have reloaded the software and it worked for awhile. Any ideas?

    I have a Canon MX882 printer and more often than note get an error message that says "Printer not Connected." When I check the printer itself, I get confirmation that the access point is connected. I tried reloading the software and that seemed to have solved the problem for awhile but I'm experiencing the same problem. Any ideas what is causing this?

    Did you delete all receipts with iDVD in the file name  with either a .PKG or .BOM extension that reside in the HD/Library/Receipts folder and from the /var/db/receipts/  folder before installing the new copy?  If not then do so and delete the new application also.

  • Time difference between the Identity system and Access System: OAM

    I was installing OAM. Performed the below steps.
    -installed identity server
    -installed webpass
    -setup of identity system console
    -installed policy manager
    -setup of access system console
    The above steps were successfull. Then when i was logging into Access system console, i am getting the below error:
    Error:there was a problem obtaining the userid. One possible reason for this is a time difference between the Identity system and Access systems (Policy Manager and Access system console).+
    The Identity Server, WebPass and Policy Manager are installed on the same machine.
    Userdata repository: OVD 10.1.4.3
    Policy and Config Data Repository: OID 11.1.1.3
    OAM: 10.1.4.3

    Found document in metalink similar to this issue. suggested to change ldapmaxofreties. but didn't help.
    Any idea on this error. Please Advise.
    Thanks in advance.

    Try this::
    Check Time Difference Between Identity and Access Manager Systems
    Check the logfile in the Access Manager install directory. The default location is <$AMinstall_dir>/access/oblix/logs/oblogfile.
    If the file exists and it contains following line "skew = slack = " that means the Identity and Access Manager Web Servers are on different machines and have not synchronized time within a minute.
    Either synchronize times between the two machines within a minute's accuracy or you can increase the slack by modifying these two files: <$AMinstall_dir>/access/oblix/apps/common/bin/oblixbaseparams.lst: loginslack: <$IMinstall_dir>/identity/oblix/apps/common/bin/oblixbaseparams.xml: loginslack: where numofseconds is more than skew found in the oblogfile.
    For example, if you have following line in oblogfile "skew = 121 slack = 60", set numofseconds in the two parameter files to 130. After doing this, Stop the Identity Manager Web Server. Then stop the Identity Server. Start the Identity Server.
    Then start the Identity Manager Web Server. Start a new browser session and see if you get the same error.

  • Is there a difference between the LG EnV3 and the LG EnV3 VX9200 is this the same phone. the reason I ask is because one says it has internet access and the other one doesn't

    is there a difference between the LG EnV3 and the LG EnV3 VX9200 is this the same phone. the reason I ask is because one says it has internet access and the other one doesn't

    It the same phone but you don't have to have data on it if you don't want since they are older phones.  We had these phones without data as I didn't think they would be good for surfing the net compared to a smart phone.  Mary

  • Certificate between Access point and Wireless client

    Hi;
    is there anyway to configure a certificate between the wireless AP and clients to secure my username and the password.

    I need the client to trust  the certifcate before entering the UN/PW

    Hello,
    As per your query i can suggest you the following solution-
    LAP authorization can be performed in two ways:
    Using the Internal Authorization list on the WLC
    Using the MAC address database on an AAA server
    The behaviors of the LAPs differ based on the certificate used:
    LAPs with SSCs—The WLC will only use the Internal Authorization list and will not forward a request to a RADIUS server for these LAPs.
    LAPs with MICs—WLC can use either the Internal Authorization list configured on the WLC or use a RADIUS server to authorize the LAPs
    This document discusses LAP authorization using both the Internal Authorization list and the AAA server.
    For more information refer to the link-

  • Layer 3 to the Access Layer and MPLS Design Considerations

    Hi,
    We are about to install a new network consisting of Cat 4500s with Sup7E at the Access Layer, with Nexus 7000 at the Distribution and Core layers.
    We have 14 floors with at least three 4500s on each floor. Within the office block where the Access Layer and Distribution Layer reside we need to support secure borderless networking using 802.1x to place users from different parts of the business into segregated networks at layer 3.
    All switches will have the feature sets to support MPLS/ VRF / OSPF / EIGRP / BGP etc.
    We quickly dismissed the idea of using VRF-Lite due to the sheer number of Vlans we would need to managage and maintain,  the point to point links alone just to get one additional VRF on each floor required far too many Vlans.
    As a result we are now considering deploying MPLS. The obvious benefits include scalability and manageability, the fact that all switch to switch links can now be routed, instead of having to using SVIs.
    My query is one of design surrounding MPLS and how this maps to an enterprise network with a routed access layer. Do Cat 4500s become the CEs and take part in MPLS / BGP and Label Distribution, or does the BGP peering and Label Distribution only occur between the Distrubtion - Core - Distrubtion layers, mapping to the PE - P - PE topology in an ISP environment, the access layer simply uses the IGP (OSPF in this case) to learn routes ?
    Any help would be greatly appreciated.
    Chris.

    Hi Andy,
    Thanks for your response.
    I have been doing a little bit more research it seems the Cat 4500s do not support MPLS!! Nor do Cisco have any plans to support it on this platform. I find this a little rediculous considering the level that Cisco are pitching this platform. With the Sup 7E only VRF Lite is supported, with plans to support EVN (which still uses trunk links for logical separation).
    So it looks like we are going to have to go back to the drawing board.
    (perhaps we should have gone HP or Juniper!)
