what the 'no nat?

I need nat, so I do not use nat, but it doesn't, but even I use the nat (inside) 0 0, I can just ping the other end, the other end can not ping back, finally, the "nat (inside) 0 access-list acl - in ' solve this problem.

My question is:

What is the "no nat" and "nat (inside) 0 0 0" really means?

Thank you

by defult the pix must do nat in order to get high to low level of security access. This is a problem if you use the public ip address in your inside interface (for example) that do not need (nat) and here comes the command nat 0...

  • Access after you turn off the router/nat [WCG200 v1]

    I use the WC200v1 for a while and it was a lot of work.  I disabled the router/Nat and comes to be used as a modem only.  After you disable the routing/Nat, you are given an IP address, which still allows access to the device.  I don't remember what is this IP address.

    I have another device offering routing/WAP capability.  The WCG200 acts ONLY as a modem.

    Someone knows what IP to use to still access the device or should I just connect my PC directly after performing a factory reset.

    Thank you!

  • The Global NAT FVRF questions - for Expert

    Hi Expert,

    I have a client with a DMVPN network. Here is a simple drawing of installation:

    First I set the router og BRANCH1 config: BRANCH1 - Config.txt

    What the client wants is simple:

    Host 200.200.200.200 reach the host 192.168.100.2 on port 3389.

    So I thought to do the static NAT like this:

    IP nat inside source static tcp 192.168.100.2 3389 100.10.10.2 3389

    but it does not work because the BRANCH1 router is configured with FVRF who wants to say outside interface is in a VRF and local area network inside interface is globally. I couldn't see any traffic coming to the server (192.168.100.2) but I could see the translation in the nat process.

    So I tried to configure the virtual interface of NAT (NVI) I read that NVI works best in the VRF environment. This time with these lines:

    interface FastEthernet0/0
    Description * WAN connection *.
    bandwidth 20000
    IP vrf forwarding DMVPN-VRF
    IP 100.10.10.2 255.255.255.0
    IP access-group OUTSIDEACL in
    activate nat IP
    IP virtual-reassembly
    automatic duplex
    automatic speed
    !
    interface FastEthernet0/1
    Description * to connect to the computer 3 *.
    IP 192.168.100.1 address 255.255.255.0
    NBAR IP protocol discovery
    activate nat IP
    IP virtual-reassembly
    load-interval 30
    automatic duplex
    automatic speed
    No cdp enable

    IP nat source static tcp 192.168.100.2 3389 100.10.10.2 3389 extensible

    Then I finally got some entries of traffic in the server 192.168.100.2. See the Wireshark log:

    200.200.200.200 192.168.100.2 TCP stgxfws > ms-wbt-Server [SYN] Seq = 0 Win = 64240 Len = 0 MSS = 1260


    192.168.100.2 200.200.200.200 ms-wbt-Server TCP > stgxfws [SYN, ACK] Seq = 0 Ack = 1 win = 64240 Len = 0 MSS = 1460

    So far so good but but... the router sends an ICMP destination 13 unreachable code to the server:

    10.1.0.1 192.168.100.2 ICMP Destination unreachable (Communication administratively filtered)

    I guess that is because the router performs a search in the global routing table instead of the destination FVRF.

    Anyone know how I can fix this problem?

    Maybe a solution to HUB1 for this so everything is managed central, what do you thing?

    Best regards

    Laurent Rlap

    I can't spoke1 config. But first the routing needs to work and I would like to try a leak of the VRF the way in Global.

    IP route 200.200.200.200 255.255.255.255 FastEthernet0/0

    When this is fixed we can watch NAT.

  • Satellite L755D-S5104 - does not know what the problem

    Hello
    I keep a L755D-S5104.
    AMD A6 3420 M with Radeon 6520G
    4 GB of Ram
    500 GB hard drive.

    The problem with my laptop recently is that I am getting i/o device error (WriteToDisk) errors thus the laptop hangs / crashes with a screen of jibberish/sand-of looking.

    So far, I got error screen with my PC as well before and I'm pretty sure it's because of the unstable driver for video/chipset. I solved as before with the installation of older drivers (but for my laptop, I can't find a choice of versions)

    I don't know if my hard drive is the cause which as well (due to the error WriteToDisk) since mainly these two errors occur at the same time. Maybe my drive is in good health, but the video/chipset driver is causing the problem?

    My laptop temperatures are normal and there is no noisy fan noise etc.

    HDTune bad block scan displays the status of my drive HARD 100% OK but the chkdsk /r utility accidents near about 45000/67000 (screen white/jibberish causes), also, I have attached my laptop HARD drive to my computer and run the chkdsk utility it without error.

    I don't know what to do? Given that I've hardly know his choice of drivers for S5104. The error started to appear since the last two days and before that my laptop was perfectly fine.

    On this virtual path, it is not easy to say what the problem is. What you can try is to do some tests and, as I see you do this very well.
    Try to get the new HARD drive and install original recovery image on it and to experiment with the settings and clean the preinstalled OS. If you do this thanks for posting comments.

    By the way: all the drivers, you should be able to find on http://support.toshiba.com/drivers
    Just put Satellite L755D-S5104 from here and you will get the list of all available drivers.

  • What the hell is an environment to help HP UEFi

    OK, HP support assistant told me that a new important upgrade was available for my laptop, UEFI support environment 4.2.5.0Ap1.  So maybe as a sheep I downloaded.  It creates a new partition on my hard drive (TOOLS HP) and installed.  Nothing serious took place, but what the hell did I download?  I have, of course, wrongly, that it was an update of an existing product.

    Because now I'm assuming that is I don't know what it is that I should not play with it.

    Thank you.

    Hello

    What this gives you is a user-friendly user interface more executing diagnostcs.  If you type following the esc key you start Notepad, you will be able to select this diagnostic menu (f2 key).

    For example, if you want to run a test on the drive hard or memory, this use is in the meu to bios (f10) where you browse and run the tests using the arrow keys and touch.  Menu diagnosis uefi will allow you to choose a variety of tests using the Mouse/touchpad in the same way that you access Windows.

    The new partition (HP_TOOLS) contains the files needed to support this interface.

    Another point to note is that this provides also a safer way to update the bios if you need to-instead of the bios flash running in Windows, in the environment of uefi, the flash occurs after the machine is restarted - that is to say before Windows loads.  It is usually safer that software which may interfere with a flash of the bios (software security etc.) is not running.

    Personally, I would only update the bios if it solves a problem you have or adds features that you need.

    Kind regards

  • What the 'cinematic' on the F5, F55 look?

    Ive been carefully after the F5 and F55 and my only concern was that most of the images shown so far has this 'look of Sony' (very strong and cooked in the oven) and less cinematic than saome of the other high-end cameras. I LOVE all things/functions/form of the new Sony factors but the so-called 'look' is what the customers want ultimately to feature films.

    I've recently went to the AbelCine event and was side by side the F65, F55. The F65 was nice and film but the F55 just seems so much.

    But someone on the mailing lists said they turned a few fottage and put to will/Aces and they said that the movie was a lot more cinematic.

    WHEN will be shot footage in the settings/formats more cinematic etcs. and placed in a good program with a good colorist for once that in for all that I can feel comfortable buying a premium movie camera that has a high-end "FILM" look?
