Removed ip access-list & lost network connectivity

An access-list was removed to edit and replace. Once the access-list was removed we lost network connectivity to the remote router. This list is an extensive one. But when we remove on other remote routers network connectivity remained. Can anyone tell me why? Is this a typical of access-list, and good practice is to wait until after business hours?

No problem.
I am sure that we have all had experiences of looking at things we have written, or questions answered, and realized that what we wrote was not quite what we were thinking as we created it.
Your main point is well taken that it is good practice to remove the access-group before removing and changing the content of access lists.
Sometimes I take a slightly different approach: I will build a new version of the access list using a different number (if I am changing access list 101, I may create list 102) which is the modified version of the list. I then change the access-group to reference the new version of the list. This may have a couple of advantages including the fact that the interface is always protected by some access list. Also it makes backing out changes easier if we discover that there was some flaw in our list modification.

  • Internet Gateway Listed in Network Connections

    Anyone know why I would have an Internet Gateway listed in Network Connections?  If I disable it I cannot access the Internet.  No other PC in my home has this, except one desktop.  Running XP.
    Thanks

    Solved!
    Go to Solution.

    My advise is..
    If you do not have at least two game consoles behind this router, turn off UPnP in the router.
    This is done in the router at Advanced -> UPnP.
    By game consoles, any two..
    #1 For example: X-box, PlayStation.
    #2 A special type of computer with no keyboard or mouse. And it is usually connected to a TV.

  • Chat Windows are closed on lost network connection

    Hi,
    Lync seems to behave a little bit differently from the Communicator regarding lost network connectivity.
    As soon as Lync looses the connection to the server (e.g. by switching from LAN to WLAN) it logs off and
    closes all chat windows - which is the main annoyance.
    Can this behaviour be changed somehow so chat windows stay open and their content isn't lost?
    Due to legal restrictions automatic saving of chat history is disabled - so that's no alternative to access the lost chats.
    Any help/ideas appreciated.

    Hi,GGerlan,
    Unfortunately,As soon as Lync looses the connection to the server (e.g. by switching from LAN to WLAN) it logs off and
    closes all chat windows this is by desgin,however you can check the conversation history when you switch from Contacts windows to Conversation windows in Lync client control panel and then click on the contacts to open the conversation windows
    with missed conversation history.See below screenshot
    Also if you deployed Exchange and you can check the conversation history in your outlook conversation history folder.

  • App says "Lost network connection, restart app"

    my banking app comes up with "Lost network connection. Please tap home below and restart app"
    I've tapped home twice, slide up the app and tried again - no luck.
    Please help.

    This issue can most likely be solved by contacting the developer of the app. That information in is the information about the app in the App Store.

  • Indesign Lost network connection of open database

    The Indesign is stopping with this error.
    Lost network connection of open database
    How to solve this problem?
    Message was edited by: jcnet

    Hi, I discovered in (Win 7 & 8 I assume) that if you go into your network adapter settings and click 'Configure' then go to the 'Power Management' menu there is an option to 'Allow the computer to turn off this device to save power'. I unchecked this and now no more crashing with the network connection lost error. Not sure it will work for everyone but might be the solution for some.

  • Lost Network Connection | Safari & iMail | AppleTalk & TCP/IP O.K.

    Lost Network Connection | Safari & iMail | AppleTalk & TCP/IP O.K.
    Well ... all of a sudden my iMail and Safari will not connect to the internet.
    I can see other Macs on the network.
    I can use the same iMail account settings on other Mac's O.K. and other Mac's can browse the internet O.K.
    So it's a sudden local Mac problem, not a network or SMTP thing.
    Any ideas anyone?
    Has Safari or iMail suddenly broken and one effects the other?

    Turns out the 'node' on the hub had failed completely, ethernet cable was OK.

  • Fascinate lost network connection after last Froyo update.

    Anyone know how to fix this issue. After updating to the knew froyo upate last month my sons phone lost network connection and won't connect. It doesn't even show up in the settings for him to be able to connect. He can still make calls and connect but nothing data wise. Plus he still gets missed calls so that update never worked for him either. Please help and thanks.

    I understand how frustrating this must be. My personal device had this problem and I found a solution that worked for me. Hopefully it will work for you as well.
    1. Put the device in Airplane mode (hold power button and select airplane mode)
    2. Wait 3 minutes for changes to take effect. You should see the airplane icon in the notification bar as well as the airplane lock screen.
    3. Power the device off and wait 15 seconds.
    4. Power the device on. Once sense loads, turn airplane mode off.
    5. In the settings>Wireless & Networks Menu, check the box entitled "Mobile Network"
    6. Everything should re-provision and data should be restored.
    If the steps above do not resolve you issue you may want to try a master reset. Resetting the phone deletes all data, including downloaded applications, and resets the phone back to its initial state—the state before you turned on the phone for the first time.
    Important: Make sure to back up important data you have on the phone before you reset your device.
    Master Reset:
    From the home screen, touch Menu
    Touch Settings 
    Touch SD & phone storage
    Touch Factory data reset
    Tap Reset phone 
    Tap Erase everything
    Reset may take anywhere from 1 - 10 minutes for reset and restart depending on amount of data on device.
    I hope this information has been helpful.

  • Lost network connection after standby on Satellite P200

    Hi
    Laptop Satellite P200
    OS VISTA 32
    When I stop working with laptop I usually close monitor and when next time open laptop computer lost network connection.
    Then I have to renew IP config and internet start working.
    Does anybody know why and how to avoid this?
    End I still want to use standby options.
    Tnx for any idea
    Sandi

    Hi
    In your case I recommend updating the BIOS and to enable the option Wake up on LAN in BIOS and in the Vista.
    In Vista you can enable this in device manager -> LAN card properties -> Advanced tab
    Additionally a LAN driver update would be advisable.

  • Accessing iTunes store network connection

    whenever i try to access the itunes store, it just says accessing itunes store and then after awhile says the store could not be accessed as the network connection was reset???
    what do i do?

    Problems connecting to the iTunes Store often stem from issues with the Windows firewall or a firewall in a router, a privacy filter (such as McAfee Internet Privacy Service or Norton Internet Security), an antivirus/antispyware utility, or a download accelerator. Start here:
    iTunes for Windows: Overview of Music Store Errors
    for some basic tips to start isolating the cause of the problem. What you need to do is temporarily disable any such service and see if that fixes the problem. If so, then if it's a firewall/Internet filter that's causing the problem and you'll need to set the offending service to allow iTunes to connect to the iTunes Store.
    Hope this helps.

  • How do I remove custom access on a networked external drive?

    My external drive (1 partition, named Zumtobel) is networked to my MacBook. It is USB connected to Airport Extreme. Everything works perfectly -- including Time Machine -- even though TM is always wanting to redo the backup to ensure accuracy.. But the info pane on Zumtobel shows that I have custom access. There is no padlock. Greyed out is Everyone showing no access.
    I am pretty sure I know what caused the problem. When setting up the drive, I had it USB connected to my MacBook. I then reconnected it to the Airport Extreme, set up Time Machine, and put on a bunch of media files. Instead, I should have started from scratch with the drive first connected to Airport Extreme and then partitioning with Disk Utility before I installed Time Machine and the media files.
    Now, when I remove the external drive and USB connect it to my MacBook, the padlock and all my options for sharing and permissions all appear.
    My question now is that without having to start again back at square one, repetitioning the drive off Airport Extreme, is there a way to remove the custom access by using commands in Terminal? Or any other way without destroying data on the external drive?

    1 go to Terminal.
    2 type 'man chmod'.
    3 navigate in the command line to the drive you want to update.
    4 use what you learned from the man pages.

  • Satellite Pro U400 - Lost network connection after suspend

    I have a Toshiba Dynadock. My network is connect directly in dynadock.
    When suspend my Satellite Pro U400 and after restart for continue working I lost my network connection. Then I shutdown my computer and disconnect/connect Dynadock I can continue working.
    What's the problem?
    Version software Dynadock is 2.0

    Hi
    I see you have switched from Vista to XP.
    First of all I recommend updating the BIOS.
    As Im not mistaken you should find a newer BIOS version on the Toshiba European driver page.
    Then you have to update the Win XP to the latest state!
    The XP should be up to date and all service packs, patches and MS fixes should be installed in your notebook.
    Then access the device manager and mark in every USB root hub you have to disable the option called Allow the computer to turn off this device to save power
    You can find this option in properties -> Power management tab

  • Disabling DataSocket Access to Specific Network Connection

    Hi Group,
    I have DataSocket server running on a PC with two active LAN connections (2 x Network cards).  The main connection is to our corporate LAN/WAN.  The secondary connection is to a fixed set of several computers for our monitored process.
    The way the system is currently configured, the Datasocket server broadcasts datasocket data to both connections.  For this application I want to disable data broadcast on the Corporate LAN while retaining it on the secondary LAN system.
    Is there a setting in Datasocket Server that I can use to prevent it from broadcasting to the primary network connection?
    Is there some other solution (eg. Port blocking) etc that I can use that may be more suitable to this requirement?
    Any advice is appreciated,
    Thanks,
    Laurie

    Hello,
    I don't think I understand exactly the functionality you are looking for.  Is it that you would like DataSocket to be available on the LAN, but not to someone who imitates a valid IP address?  This would be tricky, because it comes down to a network security problem I guess.  The server can be launched and configured programmatically; would it be possible to monitor and change the number of allowed connections to restrict imitations?  That is, you could have an application which allowed a user to login... if they login, they get access and you increment the number of allowed connections.  When they logout, you would decrement the number of allowed connections.  This way you would at least have the added security feature that a user would have to know certain login parameters in order to gain access, and not simply connect a PC to the network.  i realize there would be some details to deal with if this is even sufficient, but perhaps you can comment on the plausibility of this, and perhaps clarify precisely what network activity you would like to restrict!
    Thank you, and I hope we can find a clean solution to this problem!
