VTI problem

Could Hello someone help me? I created VTI tunnels between HO and branches HO is 3925 and branches are 871 and 881, configuration is very basic, and when traffic goes through ping tunnel rises very strongly from 200 to 1000 ms, CPU on 871 and 881 is ok, how can we improve this problem?

    Hello

    I'm trying to set up the VPN Site to Site between the CISO 3925 to PFsense firewall, phase one is in place, but when he tries to open the phase 2 I get an error to the PFsense firewall that said networks in SA is not configured properly

    as far as I know on the CISCO router that is configured with VTI I'm not supposed to set up a LAN and remote network's crypt just everything that happens in the tunnel

    It depends on the implementation of this 3rd party device. I got the impression which protect a tunnel interface.

    It seems that your box puts the card encryption on the public interface.

    Optionally, you can reach the management interface via the tunnel interface. If this isn't the case, you should return the config.

    The card crypto config seems to be the only way.

  • Need of the ACL kung fu for VPN from Site to Site ACL problem

    Group,

    Have a little problem I know is related to ACL. I wanted to have a few experts to take a look at my config please. Here's the question:

    Attempt to create a site between two offices, but for some reason any that they cannot ping each other. It is a strange thing.

    97.XX.231.22 <-->71.xx.160.123

    I can ping both firewalls from the outside using a computer to another, but from the internal firewall utilities, they cannot ping each other. At the same time I can ping to their respective gateways.

    Secondly, I did an interior outside translation as you can see here for 80 & 443 preventing me from browsing http and https via VPN for Remote LAN, can it be modified to allow access? I can access when I dial in via VPN client but not via permanent VPN tunnel. Here is the config.

    There is more then one way how you can achieve this goal.

    (1) the best way is possible if the two VPN counterparts are IOS routers. Then you can migrate to virtual VPN - tunnel interfaces (VTI). With this, the external interface doesn't mix - and non-VPN-traffic VPN.

    (2) if VTI is not possible, you can restrict the translation to only non - VPN traffic using a roadmap:

    object-group network RFC1918

    10.0.0.0 255.0.0.0

    172.16.0.0 255.240.0.0

    192.168.0.0 255.255.0.0

    NAT-SERVER - 10.41.14.103 allowed 10 route map

    corresponds to the TRAFFIC-NAT-SERVER IP - 10.41.14.103

    TRAFFIC-NAT-SERVER extended IP access list - 10.41.14.103

    deny ip host 10.41.14.103 object-group RFC1918

    permit tcp host 10.41.14.103 eq 80 a

    allow a host EQ 10.41.14.103 tcp 443

    IP nat inside source static 10.41.14.103 71.xx... map route NAT-SERVER - 10.41.14.103

    What makes that?

    When your server communicates with a system with an address in the range RFC1918, then the road map does not correspond and the translation is not used. It is you, the VPN scenario. But if the server communicates with a non-RFC1918 address, then the translation is used and the server can be reached.

  • MacBook Pro display problem

    Hello members of the community.

    As of recently, I have noticed some glitches when feeding on my MacBook or awakened from his sleep.

    The colors are distorted, usually with pink, green, or yellow blobs. Blobs cannot entirely replace the colors, they appear to be contained in a element would normally be. For example. the menu bar will be partially pink and white, but pink does not leave the menu bar in this area, and the Office has green lines on it.

    I tried to take a screenshot, but the problem resolves in about 20 seconds, but it's a recurring problem.

    It happens when I wake up, connection or not. I had also certain powers serious and problems of performance, such that my MagSafe LED would not illuminate when plugged on rare occasions, fan could turn unnecessarily, graphics performance were SUPER slow, and the health of my battery was running out quickly. I actually ran a report on the system at 2 different times and my quality of full load is depleting of 1.2% per charge cycle, which is very worrying. I went from 6281 mAh mAh 6138 maximum capacity after two cycles of load. I'm tracking closely it because at this rate, my battery will survive only at load cycles about 150 instead of the 1000 expected, gives me the idea that this could very well be a bad battery. The computer is also warm to the touch while you sleep, not connected to the power supply. I NAP active but even taking into account should not be hotter my iPhone did the same thing.

    I have reset the SMC, and it solved a couple of problems. The charger works fine now and my performance improved considerably (which made me feel better, either it is a high-performance laptop, a 11-inch MacBook Air should not he surpass), and battery life has improved. I feel even if it uses a lot of power in his sleep. Maybe I need to turn off the NAP and see if that makes a difference. The graphic bug still persists however, and I don't have enough time to see if the max battery is depleting again.

    In regards to the bug, is there something that can be done? Basically, I want to assure you that I took all appropriate measures or if someone else has this problem to see if it can be software related instead of my computer.

    I have the entry level MacBook Pro with the retina, last generation.

    Any constructive contribution welcome!

    See you soon.

  • with IOS 10.0.2 - 5s iphone Bluetooth problems

    Since upgrading ISO 10.0.2 my M50 from PLT Plantronics (helmet unique headset) do not reliably connects with my iPhone 5 more. I have to go to the settings, activate bluetooth turned off/turned on, touch the device on the bluetooth page, etc. Once it connects successfully, it will reconnect (if I turn off the headset and turn it back on) for a short period. The next day he does not connect itself but I play with bluetooth on the iPhone again.

    It has always worked perfectly before the 10th of IOS.

    And, as I noticed others mentioning, the volume is much lower with IOS 10. The maximum volume is much lower. I can barely hear it now, more normal background noise, while driving.

    I did:

    Forget this device for the PLT M50 and paired again (several times)

    I did a Reset Network Settings

    I don't know what else to do - but it's a 10.0.2 IOS issue.

    Hello AppleUser2k,

    Please ask questions about your problems of connection between your iPhone and your Plantronics headset since you upgraded to iOS 10. I understand how important it is to have your Bluetooth devices connect with your iPhone with reliability. Here's what I recommend.

    The first thing we want to make sure is that all your data is safe. You can perform a backup in iCloud or iTunes using this article: backing up your iPhone, iPad, and iPod touch.

    Once your data is safe, try the troubleshooting steps in this article to help: get help to connect a Bluetooth accessory with your iPhone, iPad or iPod touch device should also check with the manufacturer that the device has all the drivers and firmware to work with the new version of iOS.

    If you have checked everything and that you have installed the latest firmware or driver and always are problems, please be aware of your surroundings when you encounter these problems. If you can isolate the time or location, you see the problems, you can isolate the cause. You can even see this help article to ensure that you are not affected by outside interference: the potential sources of Wi-Fi and Bluetooth.

    Thanks again and have a great rest of your day.

  • Problem activation ISO 10 September 2016

    After my Ipad iOS 10.0.2 update I could not activate because it says I am not access with the original Apple journal. Makes no sense. I bought the new Ipad in seven of 2013 Dabs.com. She has been linked to my Apple account 10 days ago (I deleted my profile by own Apple support Web site suggestion as a way to fix my problem, the other restoration/upgrade to the Ipad with ITunes update). I contacted the support of Apple (I have two numbers in case Apple). Asked Apple support to provide a proof of purchase I made. Told me now the reception that I provided does not correspond to my Ipad, but Apple isn't going to help with all the details to help to regularize the situation. The Ipad is mine and well was linked to my account from the date of purchase in September of 2013 until I removed it at the suggestion of site specific help from Apple. I now do not have access to my ipad £460 for more than 10 days and have lost money and time talking to 4 different cooperatives of Apple, after 6 calls and none seem able to deal with a ridiculous situation. Alexandre Vitorino (Apple) seems to have the best handle on weird how this situation is. Please can someone fix this? A software update on an Ipad that I own shouldn't stop me using it and then force me to prove that I admit actually before I use it again! I'm a professional businessman who uses it for meetings of the Council. I have a receipt for my camera and get treated like a kind of criminal.

    My sincere sympathy for those who can't find their original receipt or forget their original log-in Ipad because Apple does not help, you and your Ipad will be also useless mine is currently!

    If you are in the same situation please confirm to this post. I can't be alone, if she feels like it!

    Lock activation occurs when the ID of original Apple blocking it does not match with your current Apple ID.

    Until you can bring a receipt valid from an Apple reseller or authorized, it's nothing you can do.

    BTW, the polling stations in this Apple-owned forums is prohibited. You can review the terms of use.

  • Problems with 10.0.2 update

    Hello

    I've updated my iphone 6 night on Sunday, October 02, with the 10.0.2 update of apple's software. At updating my iphone, it initially only allowed me to enter a number of characters in texts/emails and started to crash / black. I rebooted my iphone (turn turn off/lit) and it has stopped working all together do not allow me to enter a digital/access code footprint. The phone had left the charge and did not work for two days.

    Yesterday (Wednesday, October 05) I backed up my phone to the icloud and resinstalled scratch. After many hours of pursuit, my iphone allows me today, but again once hangs on applications and allows once again only a certain number of characters to type in any application.

    I am 37 weeks pregnant (considered term) and I need to access emergency calls in case my baby arrives more early. My husband works away and I have no family nearby.

    No idea how I get my iPhone to work entirely without crashing or return to the previous iPhone platform without having to now continue with local ACR? I need my laptop to work, mainly because of the situation, I'm in and need this sorting as soon as possible.

    Advice welcome.

    Thank you

    Hi Sue - A Q,

    I understand that your device hangs after upgrade to iOS 10.2, and limit the amount of text, you can enter on the keyboard. Since the normal restart has not solved the problem, please try to backup the device and using iTunes to restore it to factory settings without restoring all the data. Instead, configure the device as good as new. You can use your iCloud Apple id to synchronize between your contacts and calendars, etc. Test question to verify that it has been solved. You can use the purchase history App store for re download your applications.

    The backup of your iPhone, iPad and iPod touch

    Use iTunes on your Mac or PC to restore your iPhone, iPad or iPod to factory settings

    Download your latest purchases

    The links above should help you with the procedures, I suggested. Please use the Apple Support communities to post your question. Good day.
