It would work for a WLAN internet access?

Hi, everyone, I have a few questions about how to implement public access to Internet in our workplace that would not allow access to our local network.  We have several access points 2702 and 2504 WLAN controller.  Two of the four interfaces on the 2504 have intellectual property in the ranks of our LAN subnets.  I assigned a VLAN for public access to the Internet, but do not know how I would implement on our infrastructure past.  Instead, I was thinking about a cable connected to one of the unused interfaces on the 2504 to a port on our DMZ switch and having traffic for the public Internet, out across the demilitarized zone.  If I had to do this way, but also created a scope DHCP for the public Internet, and the DHCP scope were on an interface that had an address on the local corporate network, customers would always get the address?  What is the best way to do it?

A second question I have is about how the traffic between the access points and the controller is managed.  When a client connects to the access point, their traffic get dug to the controller and then thrown on the LAN, or the traffic goes to the local network directly from the access point?  The reason why I ask is that we have a remote office that we would like to manage the access point of the controller in the Office at home, but we do not want necessarily all their traffic going back or the office, if it was intended for office network at home, or if it is intended for the Internet.  The remote desktop has its own local internet connection and is just VPN'ing to the desktop at home for internal network traffic.  DHCP for clients at the remote office is managed by a DHCP server on the router on this effect.  A remote desktop access point connected to the controller in the head office would be able to use the DHCP server on the router to the remote desktop?  I test that out in a lab environment and I couldn't get it to work this way.  Remote desktop access point is currently running in mode independent and done a good job.  In the future, this site will also get on our MPLS and finally all traffic going to get dug towards the Home Office, including Internet access, so perhaps at that time, attach the remote AP to the controller would be better.

Thank you!

 A second question I have is regarding to how traffic is handled between the access points and the controller. When a client connects to the access point, does their traffic get tunnelled to the controller and then dumped onto the LAN, or does the traffic go to the LAN directly from the access point?

In local mode APs switch always centralized traffic, that is to say CAPWAP tunnel established between AP & WLC. If all traffic comments terminate at WLC connected switch.

In your case, if you map the traffic comments-SSID to the physical port connects to the DMZ switch, guest SSID users end traffic to DMZ switch. You must ensure that traffic vlan is not go on any other connected WLC trunk ports.

If AP mode FlexConnect, then traffic will end at the switch where AP connected locally.

    I can also access the internet.

    But when I do a tracert for office servers it is routed via office network. But when I tracrt to the internet via my router domestic routing. ??

    Isn't it supposed to go through my business network.

    Any help would be great. Thank you

    It's called a VPN split tunnel.  They channel the resources of the company by the VPN and let your internet go out via your local internet connection. Some companies divide tunnel and a few all traffic, including internet (complete tunnel).

    There is nothing you can do. This is how your system admins have set up.

    Most of the users of Win 7 cannot load the pages using Firefox, Internet Explorer works for them.

    One possible cause is security software (firewall) that blocks or limits Firefox or plugin-container process without informing you, possibly after the detection of changes (update) for the Firefox program.

    Delete all rules for Firefox in the list of permissions in the firewall and leave your firewall again ask permission to get full unlimited access to the internet for Firefox and the plugin-container and the update process.

  • Satellite C660 - no internet access via WLAN when powered by the battery.

    Hi guys,.

    Just bought a Toshiba Satellite C660 and went through the installation process and everything seemed simple and easy. However, this changed when I tried to use the laptop wireless. As long as I fed it with the AC adapter, all right. When I remove the adapter I lose the internet connection for about 3-5 minutes before it reconnects for about 1 min. Then, he constantly repeats the cycle.

    I have a strong signal that shows as "Connected" to my wireless network in the network and sharing Center, but get the message "no internet access. I have another laptop and PS3 connected to my network wireless without any problem. I disabled them both where they do not interfere with the signal, but that made no difference. Therefore, I am sure that's not the router, the modem, or the wireless signal.

    I checked to see if my WLAN adapter needs an update to the driver, but it shows that I have already installed the latest drivers. I tried to change the power settings for the adapter wireless of "Maximum Performance" all this without success.

    In addition, it works fine on battery if plugged directly on the wireless router.

    Can anyone offer advice on how to fix it, before I return it to the store?

    Thank you

  • Extend my extreme network with another extreme - waiting for internet access

    Hello - I have a new generation Airport Extreme (let's call it Extreme1) connected to a Comcast modem and it works very well. The extreme will be the router that the modem has no router function. I'm trying to expand my network to another room with another extreme (let's call it Extreme2). I have a connection cable between two rooms. Extreme1 has an ethernet cable from one of its LAN ports connected on port WAN Extreme2. When I try to create a new network with Extreme2 (in aid of the same name, passwords, etc.) it does not work. He was suspended at the end when he is looking for a connection ("Waiting for internet access")-I did the following things based on what I read here:

    1. Changed IPv6 link local parameters
    2. Tried the whole upward on my Macbook and tried on my iphone
    3. The Wan first and then tried to change the configuration after you done for Extreme2 by creating a network
    4. Tried to create a network with Extreme2 connected directly to the modem
    5. Extreme2 factory reset after every attepmt

    And nothing works. Kicker is, I also have a reasonably new airport express and the same thing happens to her as well.

    Do I need to adjust some parameters of network that I'm not aware of? Is it possible that my LAN ports are disabled on Extreme2? It is brand new.

    Thanks for any help.

    Have you used the Apple Setup Assistant?  If you did, it had notified you that the extreme second was being configured "add using Ethernet. The wizard will automatically configure the second airport with the appropriate settings for you.  All you have to do is enter a name of device for the second AirPort Extreme.

    Here I'm assuming that you reset the second extreme to parameters by default until you set it up again and that your second Extreme is the current version of the "tower" or that of previous versions "flat or square.

    The example below shows an AirPort Express as the device which is the extension of the network, but you will see the name of your network and AirPort Extreme on your configuration screen.

    Post back if you need some tips on using the "Wizard" for your configuration.

    Thank you

    It is a pity that you describe your problem WLAN so little time and we don t know what you tried exactly and what results are there.

    For properly WLAN use two hardware components must be configured right - the router itself and laptop. It will be interesting to know on what are the instructions you wrote.

I am traveling and need access to the internet but cannot fill all the required fields, it will bring up the top gray bar with the top and down arrow (they don't do anything, I tried pressing all there) but nothing else, just white space below.

    I suspect a lot of these errors occurred when I updated to version 9.1 of the software as it is not the only problem I encounter now, however, at this stage, it is the most frustrating.

    Thanks in advance to anyone who can help me.

    It looks like that your keyboard is not appearing when it should. I'd leave the applications that are run in which you try to get the keyboard works as well as the application of the parameters:

    Force an app to close the iOS
    https://support.Apple.com/en-us/HT201330

    1. press the Home button twice quickly. You will see small glimpses of your applications recently used.
    2. slide to the left to find the application you want to close.
    3. push upward on the overview of the application to close.

    When you have done that reboot the device and test again the question:
