Found NAT related bug in IOS

Hi
I've discovered a problem with NAT on a 2651XM ios 12.4(15)T14.
Static NAT entries work fine, but NAT overload (either from a pool or using an interface) exhibits an annoying problem.
The first outbound packet of a new connection is always dropped.  I assume this is not the expected behaviour.
The delay before retransmisson of the initial SYN packet makes web browsing in particular very slow.
I've searched the bug database but came up blank.
Kind Regards,
Alex

This forum is really more about the tool than about specific bugs.  You might get a better response on one of the Network Infrastructure forums.
That said, I happen to know that this looks like

Fixed in 12.4(15)T15.  Also not present in T13.

  • I found a bug in iOS 4.3.3 - Long voice memos

    Hello,
    i found a bug in iOS 4.3.3 for my iPhone 3GS
    Long voice memos can not be played
    In these cases, the iPhone saves the file not in the format M4A or can not open this file.
    This file is stored in the folder /var/mobile/Media/Recordings
    In This cases there can be find a file in the format MOV.
    During recording, the voice memo has the format MOV.
    When the voice memo stopped the file must be stored in the format M4A.
    For large files, there are currently problems.
    I use the program  iPhone Explorer and save the MOV-file on my computer.
    Now i can open it with QuickTime.
    Best regards from Germany!

  • I've found two bugs in iOS 7. 1) declined calls does not appear as missed calls on the lock screen/notification centre. 2) when bluetooth is enabled from control center, it does not connect to an already paired bluetooth device

    I've found two bugs in iOS 7:
    1) declined calls does not appear as missed calls on the lock screen/notification centre - iOS 7.0.2.
    2) when bluetooth is enabled from control center, it does not connect to an already paired bluetooth device automatically - iOS 7.0.

  • Dear Apple, unfortunately, I think I have found a bug in ios 7. During an incoming call is no call rejection or selection of the ability to send a text message. I hope it is a bug and there is a solution. Thank you very much.

    A good read. Have you done anything at all to resolve your problem. Reset? Restore?
    By the way - "your products"... nobody here produced the iPhone, we are all just users. Apple is not here.

  • I found a bug in IOS

    Where can I report it?
    I assume I'm not the first one, so where can I check any further details? Maybe it's not even a bug
    It's delated with BVI - Bridge-Group Virtual Interface. It won't come UP, unless you type
    "R1(config)#interface bvi 1 ?"
    That question mark at the end is the key that will enable BVI interface. You don't need to press enter. It took me a few days to figure it out...

    I noticed another bug in IOS. This time on static DHCP settings. You need to have default-router entry otherwise it doesn't work.
    Here's sample config:
    ip dhcp pool STATIC
    host 10.10.10.10 255.255.255.240
    client-identifier 0122.5b27.1f62.aa
    default-router 10.10.10.1
    Thisway is working, but without last command - it's not working.
    "show ip dhcp bindings" is properly showing that static entry exists, but router doesn't assign desired IP. I'm using universal IOS v15 on cisco 800 series.

  • Bug Report iOS 7 iTunes. Since it is repeatable on 3 iPhones and 4 iPads here, I'm sure others are experiencing the same thing. Apple, might want to take a peek at this. When a tv show or movie is deleted from Videos, the Videos app shuts down.

    Restarting videos works and looks like video is getting deleted.
    Just a bug report

    You might want to report that to Apple instead of to the other users in this forum.

  • What is apple doing to fix the bugs from IOS 7.1.2 update? this update has ruined my phone

    What is Apple doing to fix the bugs from IOS 7.1.2 update??? This update has ruined my phone! Why would you put out a update you know is going to ruin someones phone? Whats being done? I have tried everything to fix my phone which was just fine before Apples IOS 7.1.2 update!!!

    I have also experienced issues with my iphone5 since updating to ios 7.1.2, prior to this update my phone was working perfectly fine and I know I didnt cause any damage to the phone because I baby my iphone as if it was my child. Ever since I updated to 7.1.2 my phone shutts itself down while I am using it, it can be while using whatsapp, browsing the internet or using apps, more than anything it fails while using the internet. The screen will either start to flicker or vertical lines will pop up and then the phone will fade to black, after this happens the phone will get really hot and to turn it back on I have to wait 5-10 minutes and hold down the power and home keys at the same time for about 15 seconds for it to turn back on, I have to wait 5-10 minutes because if I dont when I boot it back up it immediately shutts down again. This is a constant all day thing and for now i get by just making phone calls and sending regular text but I try to keep the action down to a minimum to prevent missing a phone call. I tried clearing the phone and rebooting it to original setting but this didnt fix it. After reading and speaking with several techs they tell me that ios 7.1.2 rolled out some performance adjustments one particular that affects the amp levels that the battery works at and supposedly the iphone 5 cant handle it, they explained that the phone for certain activities is asking for more or less power and the phone panics into safe mode and shutts itself down. My battery life is fine so I havent changed the battery like someone had suggested. In the diagnostic data it gives a panic.ips error. Id really like to know if there is any possible way to roll back to 7.1.1 through jailbreak or any other way, I was perfectly happy with this phone and didnt plan on buying another one for atleast 1-2 more years. If anyone can help me out this would be greatly appreciated, if not I hope apple is working to fix this.

    Hello,
    Same problem for me. Really a pain in the *** this bug ! Does Apple fixed it. I'm really suprised noone reports this problem  and apple does not adress this.
    Because of that, I cannot give it anymore to children because it hurts the view. Really a shame on the part of apple !

  • My iPod Touch 5 brightness suddenly turned dim but when I go to my brightness and wallpaper page in settings it is at the middle (Normal Brightness). Is this a bug in ios 6 or something?

    My iPod Touch 5 brightness suddenly turned dim but when I go to my brightness and wallpaper page in settings it is at the middle (Normal Brightness). Is this a bug in ios 6 or something?

    If the reset does not work I would try the following before going to Apple
    - Reset all settings      
    Go to Settings > General > Reset and tap Reset All Settings.
    All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
    - Restore from backup. See:                                 
    iOS: How to back up                             
    - Restore to factory settings/new iOS device.
    If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

  • "Why Apple do not fix light sensor bug in ios 6 ipod touch 4g plz give me update for this"

    Light Sensor increase but not Decreas light

    As you have been directed in the other posts you've made on the issue, this is most likely a hardware problem with your particular iPod, and you won't get different answers by posting more threads on the topic. If this was a bug in iOS 6, I'm sure we'd have seen many more posts on the problem, so this is more likely to be a problem with your iPod, not with iOS 6 itself.
