Win2K NAT would be from 1650 to a PIX 515 - does not

Hello

:

I have a working VPN config on my 515 (6.2.2) and can tunnel from one host with a valid external IP without any problem. But, with a NAT would be customer, nothing seems to work.

I use RADIUS to authenticate after using a password for the group. Here is the sequence of events.

(1) client machine as a 10.0.0.1 address, NAT had a public address to come into the port of 'outside '.

(2) the client connects, the user enters GANYMEDE password and is connected.

(3) the user tries to browse any service and can not.

(4) if the user switches DNS to an external server, the portion of the split tunnel internet works fine but inside is still broken.

(5) clients with static IP addresses that are publicly routable connect and can perform all internal and external activities of split tunnel.

Excerpts from config. I'm doing something wrong?

Permitted connection ipsec sysopt

No sysopt route dnat

Crypto ipsec transform-set esp - esp-md5-hmac noaset

Crypto dynnoamap dynamic-map 10 transform-set noaset

You do not have something wrong. The problem is that NAT (NAT actually PAT, port) and IPSec is not working very well, and many features PAT can PAT IPSec traffic to all (PIX included until version 6.3).

The problem is that PAT depends on using the port number TCP or UDP source as a way to differentiate between sessions, because they are all PAT would be from the same source IP address. However IPSec (ESP at least), tracks right on top of IP, in other words, it is NOT a TCP or UDP protocol, and therefore has no associated port number. It breaks most of the PAT devices.

The reason for which you can build your tunnel initially, it is that it is all done by ISAKMP, which is a UDP protocol, which can be PAT would be fine. Once the tunnel is built however, all encrypted data are sent by packs of ESP, which as I said, is not a TCP or UDP protocol.

Trnalsations NAT static work cause they do not rely on the use of the port number, they just change the address of the source that works very well with ESP.

There is not much you can do about it. If you were closing the VPN into a VPN3000 concentrator, it has a feature called IPSec through NAT, which encapsulates all ESP packets in a UDP packet, which can then be PAT would be properly. The PIX, unfortunately, doesn't have this feature. The only solution is to get a NAT device that manages properly the IPSEc. Surprisingly, some of the less expensive devices on the market handle it, but you should check with each manufacturer to be sure.

  • Smartphones from blackBerry Desktop Manager - Calendar sync does not

    I noticed today that my calendar sync has not worked for a week or two. Nothing moves device or outlook, they are simply not speaking.  When you click on synchronize that he told me that he is dealing with, he lights the BB with the photo of transfer, he tells me "please a moment" then stops and returns to DM (as if he did so quickly, that I missed). But it does nothing, I checked the paper, nothing is recorded for calendar synchronization.

    Tasks, Memo, and address book are all working very well (it is a non set - up) so I've unchecked them to sync, so I can focus on the calendar.

    I uninstalled the Desktop Manager (and cleaned of all research in the files of application etc.) and then reinstalled version DM 5 - which does not set it.

    I used the backup & restore, Advanced Options and schedule database deleted completely then tried one-way synchronization from the pc to the device - that did not set it.

    I tried restoring from an old calendar backup - which does not set it.

    I restarted the phone - which does not set it.

    3 hours later, I am all ideas... any help would be appreciated please.

    I wiped my handheld completely computer (settings / options-> Security-> General settings options-> push the menu button and choose "scrub Pocket")

    Restored from backup, and now the clock works again.

    If the DPI (dots per inch) is less than 100, the printer will not print the photo because it would be too low in quality. Draw the image on the computer, then right-click on it and click Properties, check the horizontal and vertical dpi and see if these figures are less than 100. Have you tried to connect the iPhone to the same network as the printer and try to AirPrint peak? AirPrint road doesn't have the same requirements on IPR as the ePrint.

    You must install the driver for Winows 7 for the camera, * if * it exists. Get it at the web site of the manufacturer of the camera.

    Also, note the following:

    You ever need connect your device directly. Buy a card reader for the type of flash card your camera uses (they are very expensive), put the flash card and plug it into a USB port.

    Personally, I prefer to do it this way. It is much easier and doesn't use the camera battery. I have two cards - one readers that I keep on my desk next to my desktop computer and another that I keep in my case of laptop for use when traveling.

  • Post photo or video from the album shared and it does not appear

    Lately I've known something very strange.  Very rarely, I go through the steps to post a photo or a video on an album shared my Photos on my iPhone, but after finishing when I type then "Shared" downstairs to check the album, the photo is not here.  It does not appear in the shared himself album, or activity.  It just is not there.  It happened several times. Basically, I am able to post fine, but this happens sometimes, apparently with nothing else.  WiFi is fine.

    Any thoughts?  It seems that there is so much it's always bugged on shared albums.

    What is happening with Albums that you share or shared Albums from someone else? It happens in the same album, or different? Y at - it albums that you try to add photos or videos of exceeding limits of sharing:

    limitations of sharing photos to iCloud

    These are sharing photos of iCloud hourly and daily limits:

    • Maximum number of photos and videos in a single contributor through all the albums at the time: 1000
    • Maximum number of photos and videos in a single contributor through all the albums, per day: 10 000

    These limits sharing are separated from the download above limit. For example, in the same day, you could upload 10,000 photos to my photo stream, then share these photos 10 000 or 10,000 other photos.

    Some additional limits to shared albums:

    • Maximum shared albums an owner can share: 100
    • Maximum shared albums, a user can subscribe to: 100
    • The maximum subscribers per shared album: 100 (the number of subscribers on each shared album)
    • Maximum number of photos and videos of all contributors in any album shared a handset: 5000
    • Maximum number of comments per photo or video in a shared album: 200 (a comment can be a text entry or a like)
    • Maximum number of characters per comment: 200
    • Maximum number of guest, owner of a shared album can send per day: 200

  • back from Win10 to Win7 now backup does not work

    I tried Windows 10, but had trouble with the resolution of the screen.  I've started using the tool provided by MS Windows7 and now backup gives me an error and does not perform a backup.

    Here is the error I get:

    Windows cannot disable the task of automatic backup for the following reason:

    The task image is corrupt or has been tampered with. (0 x 80041321)

    Try again.

    Can someone please?

    Thanks in advance!

    I finally had to call MS and they have managed to solve the problem.  Somehow when I started again from Win10 to Win7 the Task Scheduler or WindowsBackup was damaged.  The registry has also been affected.  The skills needed to repair this problem was well beyond my capabilities.

    With the assistance of MS, this problem is now resolved.

  • Transfer from one Mac to another catalog does not work?

    I copied an entire Lightroom Catalog folder from one Mac to another, and I placed it in the Documents folder on the new Mac. I expected just open when I launched CC2015, although she does not.

    1. what should I do to repoint CC2015 in this catalog folder?

    2. to do this, I can place the main folder anywhere on the computer too long that I indicate in LR it where? Are there benefits to be placed in any particular place, or is it just the preferences of the user?

    Thank you.

    IMO, you should keep records high-lit & files to the screen clip below.

    That is to say. Your most recent work catalog dated February 27, 2016 with its record of previews.

    and keep a few folders of backup.

    All the rest could be deleted.

    Catalog backups must be in the same folder as your catalog of work - if the disk drive fails you have lost a lot. !!

    The catalogue dated February 9, 2016, {Lightroom Catalog.lrcat 5} can also contain development not in the catalogue 27 Feb. -then maybe preserve also!

    You could remove the 'Previews' folder, but Lightroom will slow down a bit because he rebuilt the previews when you reopen {Lightroom Catalog.lrcat}
