Firewalls and WTK network access on startup

There was a recent change in our corporate network, and now the WTK doesn't work for any of our developers. On startup, the emulator shows a blank screen and then exits without giving an error message. If we disable our network cards, we can get the emulator to run, but since our app requires the network, this doesn't do us much good.
Obviously, our network must have some kind of firewall enabled, and the app must be contacting some sort of server on startup. Does anyone know the specific server that the emulator is trying to contact? Our IT department can't open the firewall unless they know this information.

  • WRV200 - Problems with VPN Client and Internal network access

    I have a WRV200 router and want to access the internal (Private Network) connected on the inside. I have successfully conected to the router with the Linksys VPN Client, but it does not appear to allow access to the internal network.
    How do I enable NAT Transversal or Passthru? I have already selected all of the PPTP, L2TP and IPSEC Pass Through.
    Has anyone gotten this to work?

    I have actually gotten this to work. Issues surround this include the ability to get to the VPN if the main DNS is down (it does not fail over to the next DNS in the list).
    If you unselect all of the boxes in the firewall General configuration, you can connect, but if you need to have all of this unchecked, what's the sense of having it?
    Anyway, you can use the DoS Prevention, this is not interfering.

  • Airport Extreme 802.11AC + 5th Gen and guest network access

    I have the current gen Airport Extreme 802.11AC with a 5th Gen extending the network. With this setup, I am unable to login using our guest network setup. I have tried using guest network with a password and one without but its the same results. When a guest logins, it stuck attempting to login with no error messages.
    So is it possible to have this configuration and still have guest network access?

    Please review what I said originally.......that the guest network function on the AirPort Extreme is designed to work with a simple modem......so the AirPort acts as the main router for the network..
    Another way of saying the same thing is that the AirPort needs to be "in charge" of your network for the guest feature to work correctly. The AirPort cannot be in charge if it is connected to another device that is already configured to be the main router on your network.....your Actiontec modem/router.
    The Actiontec device combines the functions of a separate modem and a separate router in one package. This type of device is known as a modem/router, or also known as a gateway.
    Some folks call a modem/router or a gateway......a modem. So, things can get confusing.
    I do not know if it is possible for the Actiontec device that you have to be configured to act as a simple modem.....so the routing functions of the device are completely turned off. (Turning off the wireless on the Actiotec does not turn off the routing function).
    If you turn off the wireless on the Actionec, it becomes a modem and a wired router. And that wired router is still in charge of your network.
    The guest network feature will not work correctly unless the AirPort is in charge of your network.
    My suggestion was for you to ask your Internet Service Provider (ISP), if they could supply you with a simple modem.  That is all that you need. You don't need two routers....and the Actiontec that you have now is not allowing the guest feature to work correctly.

  • Time machine running slow and slowing network access

    I have had and continue to have issues with wifi on my MBP.  Those are pretty well summarized in https://discussions.apple.com/thread/5535320?start=30&tstart=0.  I've been able to make mt system usable with some of the less dodgy workarounds in that thread ( like keeping a ping on my router running )
    That thread really doesn't mention the issues I've been having with time machine though, so I thought I'd bring this up here.  Whenever time machine starts up, Safari and mail become unresponsive.  It's worst when TM is "preparing" of "cleaningup", though barely usable during the actual backup.  Mostly, I can work around that too, but occationally, TM will find GB of data to be backed up and lock up my mac for a day.  Here's a recent example:

    This is on an AC router.  My peak throughput shows 19 Mb/s on menu meters, so, not great, but not this slow.  Mostly, the network activity is nothing with short bursts of higher throughput.
    I'm hoping this will be addressed in 10.9.2.  In the mean time, are there any workarounds to get past this issue short of turning off TM?

    These instructions were taken from Mac OS X Hints at:
    http://hints.macworld.com/article.php?story=20050302225659382
    The Unix program dd is a disk copying util that you can use at the command line in order to make a disk image. It makes a bit-by-bit copy of the drive it's copying, caring nothing about filesystem type, files, or anything else. It's a great way to workaround the need for Norton Ghost.
    Normally, in order to make a disk image, the disk you're copying from has to be able to spin up and talk -- in other words, it's OK to make a copy if the disk is healthy. But what happens when your disk is becoming a doorstop? As long as it continues to spin, even with physical damage on the drive, dd and Mac OS X will get you out of the fire.
    We had a situation recently where a friend sent a disk to us that had hard physical errors on it. It would boot in Windows, but then it would hit one of these scratch marks and just die. We fired up dd, and it started OK, but stopped at the same physical error location -- complaining about a Hard Error.
    So the workaround was to designate the dd mode as noerror -- which just slides over the hard stops, and to add the mode sync, which fills the image with nulls at that point. We did it on BSD Unix, but as long as you can get the hard drive attached to your Mac, the command is the same:
    dd bs=512 if=/dev/rXX# of=/some_dir/foo.dmg conv=noerror,sync
    The bs=512 designates block size, and the if=/dev/rXX# is the UNIX path to the actual disk device. Make sure that the chosen directory (some_dir) has enough room to take the entire disk image -- which will be equal to the size of the drive. Since dd doesn't care about the contents of the drive, it copies every bit on the thing, so you get an image equal to the disk's capacity. A really big file. One workaround is to put it on a RAID array.
    Once you've established the disk image (in this example, foo.dmg), you're almost home. Here's where your Mac OS X box is far and away the best thing to have. In this example, the dd output file is foo.dmg. You have to realize that this is an exact copy of a busted drive, but the "holes" are filled with nulls. As long as the damage isn't to the boot sector, though, when you double-click on it, Mac OS X mounts it without breathing hard ... who cares if it's FAT32, NTFS, whatever.
    Due to the size of the image that we were copying, we put it on a RAID array, and had to access the image over the network -- it still mounted fine. In straight UNIX, if you try to mount a disk image, it complains that there is "no block device" and fails. Once your image is mounted, it appears in your Finder, and then it's easy work to retrieve the critical files from the image -- usually things like .doc files and .xls files and the lot.
    Finally, since your disk is actually dying, once you have your image, you can drop it to tape or something and you've not only recovered your files, you've made a viable backup as well. Once again, that which destroys a Windows box becomes a play thing to a Mac OS X box.

  • Cascading EA4500s and Guest Network access

    Hi, I hope esomone can help me here. I've got two EA4500 routers connected via ethernet. The primary router has DHCP enabled and the secondary has it disabled. IP address of primary is 192.168.1.1 and the secondary is 192.168.1.2.
    I have set up guest access on both routers however only the primary router allows users to connect. When out of range of the primary router but in range of the secondary router the network is visible but when you try to connect to it, it only gives limited or no connectivity message and can't connect to the internet.
    Is it possible for the guest network access to follow the same pattern as the secure network, i.e. the same network throughout the house?
    Regards
    Jon

    Cascading two routers should have correct parameters set. For instance, the Ethernet port of the secondary router should be connected to the ethernet port of the primary one, and the DHCP should be disabled on the second router. The ip address you've set are correct for the both routers. This thing shoud be done if the connection is LAN to LAN.
    By the way there are two types of cascading: Click here for info!
    For the Guest Network:
    Guest Network would only work if the the DHCP is enabled on your router. It means to say that on the type of setup you're doing which is LAN to LAN (DHCP disabled on the second router), Guest network would not work on the secondary router. If the connection is LAN to WAN, then both of the router should have Guest Network working.

  • Open and Closed network access?

    Is it possible to have both an open network portion (no password), as well as a closed (password protected) network setup with a single Time Capsule/Airport Extreme device?
    I want to keep my data protected with a password access to the network, but would like to also have an open network for guests that does not always require a password just to access the internet.
    Thanks!

    Can you clarify what you mean by "closed network"?  Normally a "closed" network is one in which the name of the wireless network is not visible.
    If you have a dual band AirPort Extreme or Time Capsule it is possible to set up a "main" network that is visible and password protected....and a "guest" network that is "open", not requiring a password to connect.
    Important.......The guest network feature cannot be enabled if you are connecting the Extreme or Time Capsule to another gateway device.....a combination modem/router that is provided by a number of service providers.

    It has to be configured on both sides.
    X and Y are unused networks in this example: Site A has to hide 172.16.1.0/24 behind X when communicating to Y, site B has to hide 172.16.1.0/24 behind Y when communicating to X. The users in site A have to use Y as a destination, users in site B have to use X as destination. To make it usable for the users you should include the destinations in the DNS so that they never need the destination-IP.
    On the ASA you describe the communication 172.16.1.0/24 -> Y with an access-list and add that ACL to your static-command. You find an example here:

  • Wifi airport to surf and ethernet network access

    Sorry if this question has been asked before but I have not found a solution anywhere yet.
    Q: How do you set up the airport (wifi) to access the internet to surf the web; while connected to an ethernet network?
    Background; this imac is set up at work and can access the public wifi to surf the internet as long as the ethernet cable is unplugged from the back, but to browse the network files and drives and check email to do work the ethernet cable must be plugged in. But its a pain to keep walking around to the back of the mac and plugging in and unplugging the cables.
    There has to be a way to set safari to use the airport to access the internet and set mail to use the ethernet ports.
    Thanks for the help!

    The normal setup would be to an attach a wireless access point to the existing network. Then connect to that device wirelessly. So use something like an airport express. Connect the network cable that normally goes into your mac into the aiport express. Then connect your mac to the airport express wirelessly.

  • Using both wired and wireless network Access?

    I have a ThinkPad 510 with a docking station.  Within the same room, connecting to the same network I may use the WiFi with the TP only, or connect using the docking station which is hardwired to the network.  TP has W7 installed.
    What is the correct procedure for bouncing between these two environments?  Is there a setup which will allow 
    'automatic' access, depending on whether I'm using the docking port, or not?
    Thanks, 

    in the Thinkvantage Access software, you can set the network preferences. So you can set the Ethernet to be your most preferred network connection method, while your wireless as the second most preferred method. Or which way you prefer.
    So for example, when you dock and the computer detects the ethernet network connection, it will automatically switch to the ethernet as it becomes available. And when you undock, your computer will switch back to wireless as ethernet is not available.

  • Win 7 PC freeze and block network access for other PC on same switch during windows update from WSUS

    Hello,
    It's been a problem for me for a long time now, but the last time (today) I found 3 PC on 2 different switches that block all the network on this 2 switches during the update. 
    I have a Domain with 80 PC with Win 7 (32&64bit) that takes the updates from the WSUS server that is configured on a Win2k8 r2. The system works well from 2 years from now but sometimes cause this errors that make me look like a dummy in front of angry
    employees. If one of the PC get freeze , it will cause lost of connection on all the PC on same switch, and i have to find the blocked PC, remove from network, restart switch and hope that they will came back on.
    Does anyone experienced this problem? Any help will be appreciated 
    Thank you!
    List of updates for today below

    Hi
    Thanks for your response, yes I understand that the result is a Broadcast Storm and yes I have the cheapest switch on market :/.
    The interest fact is that on one PC, I changed everything and keep only the old HDD and on last updates yesterday it was one of the blocked one too. So this make
    me doubt that is something wrong in software on that PC. I don't have any third-part programs except browsers and all have Genuine Win7 
    The only investigation remained is what happens during the update process? 
    Is WSUS involved in something?
    And another thing is the fact that some of the PC are cloned, but I have carefully changed the SID
    Thank you for your support

  • ACS 5.1 and different network access profiles

    I am trying to set up radius access on 2 different SSIDs coming from an Access point.  The 802.1x rules will be different based on which SSID the user is connecting to.  One will be more restrictive than the other.
    in my example the ap is 10.1.0.1
    the ssids would be "inside" and "outside"
    for the inside ssid, I would like to verify they are a domain user
    for the "outside"  i want them to be in a specific group.  I have the group already confured in radius.
    I can do either one successfully, but I do not know how to map the device to two different access policies.
    Would this be just mapping different permits based on which authentication rule they passed?

    Hello,
    You would need to edit your existing policies and add one anothetr customized condition called compound condition ( in addition to whatever condition you may have already).. chose radius ietf dictionary and chose the attribute called-station-id. Usually the ssid is sent as part of this attribute. you can match the value to either 'inside' or 'outside' and chose the result that would best suit that ssid. I think it may be easy enough for you to take it up from this point. Let me know if the explanation isn't clear.

  • Acs 5.3 and wlc 2504 config with restricted network access

    Hello,
    i submit you the following issue that i'm actually facing:
    i must configure a secured wireless network with access restriction based on SSID. the equipements are : cisco wlc 2504 (soft 7.3) cisco secure acs aplliance 1121 (soft 5.4) .
    the users that will connect to the network are regrouped by identity groups, each identity group having it's own SSID. Clearly each group of users must access only one SSID.
    i followed the procedure below to configure it:
    -- creating user identity groups;
    -- creating users and assigning them to the groups;
    --- creating authorization profiles for each SSID under policy element/ authorization and permission/network access/authorization profiles and putting the Airespace-Wlan-Id(the SSID number) in the radius tab.
    --- assigning the authorization profiles to the identity groups under access policies.
    after all these config the users can access the network using there userid/password configured. But the problem is Every user can access every SSID, seems like the restriction is so not very well configured.
    i found some documentation on this kind of config but the version of ACS used seems older than the one that i use, so menu are very different.
    Please can someone provide with the right steps to follow to achieve this kind of config.
    tkx in advance

    Yes.. you only have to add the end filter like what I posted... as far as the calling station id in the WLC security tab, it doesn't matter because that is not used when using 802.1x.  I would also try to not enable everything that you have just to start from the basic and make sure it works first.  The WAP Authentication Method might or might not work for you.  Uncheck that for now and when you have a successful authentication, look at the monitor log and see what radius attributes are being sent, because those attributes is what you can use to build your policies.
    Thanks,

  • Time Capsule Access Control and Extended Network Question

    I have a Time Capsule where I have set up a wireless network access list…and extended the network using an Airport Express unit. The Airport Express unit also has settings for an Access Control list. Do these need to be the same as the those for the network from TC that it is extending…or does that happen automatically…and if not what on earth are they for?
    Thanks for any help…this doesn't seem clear from what I've read/seen.

    Unfortunately, they are not automatically applied to each base station in an extended network. You would have to manually enter the exact same list in each base station.

    Hi,
    >>Is there a way to lock just DNS to AD clients?
    Before going further, how was our network set up? Do we use DHCP to automatically assign IP addresses to clients? If we use DHCP server to automatically assign IP addresses, the computers connected to the network will automatically get
    their IP address and DNS server IP address if we don't have a network protection mechanism to restrict which computer can get IP address from DHCP server. In this situation, although we know that you don't want to use Network Access Protection to do this,
    as far as I know, this should be the solution which can best meet our target.
    Besides, for this is more related to network, in order to get better help, we can also ask for suggestions in the following network forum.
