The GRE + IPSEC but have no encypt certain traffic?

Hello

I'm banging my head a little bit here. I want to encrypt all traffic between 2 sites except voice.

On the cisco site, it would appear that the command "crypto map" should appear on the two physical (in this case Dialer) and on the Tunnel interface. Why is it necessary on the Tunnel interface?

I have configured the following: -.

Can anyone suggest a better way to accomplish the non-voix encryption only traffic, and also if an expert out there can explain the card crypto interface Tunnel thing, that would be great!

Thank you

Peter.

Let me explain the whole thing in its entirety.

You have a public IP address or the other site and you form a GRE tunnel to route your IPs private above the GRE tunnel. This traffic includes voice and data. Then create your IPSec policy only traffic to be corresponding encryped (u know have explicitly deny the telephone traffic) and apply the crypto map on the tunnel. Who should install the IPSec VPN for you. This is the best medium for what is as iam concerned (I did in one case as well).

Instead of carrying all the traffic thorugh one IPSec VPN and data on a GRE traffic, according to me, you can send voice traffic on free WILL and encrypt traffic IPSec over GRE.

Hope that clarifies.

  • establish the GRE/IPSEC behind ADSL router

    Hi all. This is my first post. I watch a lot to the internet so I can't find any help on this problem.

    I would like to set up a VPN with ACCORD between 2 sites, but one of them is behind a router ADSL. This router redirects all external traffic to the external interface of the router.

    The problem is that I don't know how to configure this router because only to see the crypto ipsec his you can see Start local crypto is 192.168.0.147

    and the other router to assign this IP address to complete the second phase.

    I hope that this has been explained clearly.

    Thank you very much experts!

    The problem is so much simpler if your GRE and IPSec endpoint termination ends on the same interface without NAT.  However, things get a little tricky when you have NAT involved.  In this situation, the following the following configuration example:

  • in Outlook Express, how can I send the same message to a group important (in the address book already), but have to each recipient can only see his name (not the Group)

    In Outlook Express, how can I send the same message to the large group (already in the address book), but have to each recipient can only see his name (not the Group)?

    To use the functionality of the BCC (Blind Carbon Copy), in a new message window, click View | All headers and type the addresses separated by a; Or: Click the button to. You will see your list of contacts and the choice to put them in the To, CC, or BCC field. Click on an address, and then click BCC to add it. Repeat for all of the contacts you want. (Note: most of the providers have limits as to how many messages you can send both a. 25 is common, but it varies).

    Put your own address in the box to. That's the only name/address that any recipient will see. If you leave the field empty, some people may not receive e-mail because of message rules they put in place, or restrictions imposed by their ISP.

    You can also make an entry in the address book using your e-mail address, but put something like the mailing list in the area of the display.

    *********************

    You can also create groups if you send e-mail to the same people often.

    To create a group of contacts:

    You can create a single group name (or alias) to use when sending a message to several contacts at the same time. Just create a group name and add individual contacts to the group. Then just type the name of the group in the box for when you send mail.

    1. in the address book, select the folder in which you want to create a group. Click New in the toolbar, and then click New Group.
    2. the Properties dialog box opens. In the group name box, type the name of the group.
    3. There are several ways to add people to the Group:
    a. to add a person from your address book list, click Select members, and then click a name in the address book list.
    (b) to add a person directly to the group without adding the name to your address book, type the person's name and e-mail address at the bottom of the Properties dialog box and then click Add.
    to add a person to both the Group and your address book, click New Contact and enter the appropriate information.
    (d) to use a directory service, click Select members, and then click search. Select a directory service in the drop-down list at the end of the text box. After finding and selecting an address, it is automatically added to your address book.
    4. Repeat for each addition until your group is defined.

    Note

    a. to view a list of your groups separately from the list of address book in the address book on the view menu, make sure that folders and groups is selected.
     
    b. you can create multiple groups, and contacts can belong to several groups.

    If you want to send to a group without addresses are displayed for each recipient, open the address book and make a new entry. Enter the name of the group in the area of the display, but use your address. (Some Internet service providers require a legitimate address in the line to and recipients will know it's from the Group).

    Click on the button to. Enter the name of the group using your address. Enter the group in the BCC field.

  • When I linked book FM, I have files in the project files, but no chapter file in Table of contents chapter

    Using RH9 in TC 3/Windows XP

    I've linked to a number of books in this project. A book has all the chapters files well displayed in project files folder in the project manager, but have no books in the table of related materials.  Only topics.  How to fix this problem.  It seems that I deleted all the files in the table of contents before that I can delete the TOC file in the project manager, but is it anyway to regenerate the table of contents?

    Thanks in advance for the help.

    Mary

    Hi parties,

    You don't want to say that the table of contents are different in RoboHelp compared to FrameMaker TOC, please take a look at this blog http://blogs.adobe.com/techcomm/2010/03/demystifying_mapping_filesettingisf_and_toc_genera tion.html- it might be useful.

    you don't Ned to remove the link from the book of RoboHelp can just make changes in FrameMaker or update and correct path of TOC in RoboHelp and Force the link to update.

    It should make changes in ROboHelp TOC.

    In addition to that you can change the table of contents to RoboHelp after generation according to your need (these changes are going to get is returned on the next update)

    Hope this will help

  • Recently upgraded Windows 2000 server to 2008 which does not support Netbeui. I am trying to install TCP/IP on the BACK box, but can't find a 16-bit version.

  • ThinkPad 560 X - How the hell do you have the CD of external work?

    I just bought a 560 X used to use a development for Windows 98 computer.

    HARD drive was empty. I am looking for the external CD (P/N 1969-010) to work.

    I installed DOS 6.22 software then Cardsoft for DOS. When I inserted the IBM IDE PC card, the system emits a signal indicating that it has recognized that a card has been inserted, but nothing else happens.

    I have tracked down a lot of files to options/install/etc on the support site but have not yet tried all the.

    Will try to install Windows 3.1 and using some install files for Cardsoft for 3.1 but I guess just at present.

    I have the impression that there should be an installation file/program for the CD itself, but did not find one that looks right.

    I just want to get the CD to work so I can install Windows 98. Then I need to be able to use the CD with Windows 98.

    Any suggestions?

    Solved by myself - after a few permutations.

    (1) installed BACK 6.22

    2)
    Using another system, I find the driver on the Lenovo site,
    files for CardSoft for DOS (pctpcdos.exe) and IBM 20 X Max Portable
    P/N 1969010 (820xnosd.exe) CD-ROM drive

    These two files are self-extracting compressed files. Execution of creates them a diskette in A:

    (3) BACK started on the Thinkpad X 560

    (4) Insert the diskette for Cardsoft created by pctpcdos.exe software.

    5)
    Install.exe Ran from the diskette. This installs BACK support for the PCMCIA
    cards. In this case, we want to use the IBM IDE PC Card used for
    connect the CD to the 560 X.

    (6) switched disks, inserted the diskette created for CD 820xnosd.exe

    7)
    Passed to A: and run install.exe - important, for some reason any
    the installation program does not run correctly unless you switch to the A:
    drive. Using A:install does not work. You do A: the current
    drive.

    (8) the CD is now available at BACK

    (9) copied all the contents of a Windows 98 installation CD into a directory named WIN98CD hard disk

    10) ran Windows Setup from the hard drive.

    11)
    After the installation is complete and has detected all new
    material, I used the point to install new hardware from the control panel
    looking for a new material that was not installed.

    (12) the CD
    has been located. I put the Setup CD disk (created in step 2 of the)
    file 820xnosd.exe) and made the installation of the driver to the A: drive.
    Windows finds the correct driver and - hop, the CD player is now
    recognized and is usable from Windows 98.

    After getting the CD
    working, I used the other drivers that I found during my search of the
    Lenovo - things like audio and video - site and install them.

    Here
    is a complete list of the files that I downloaded from the Lenovo site. They
    include various support for BACK, Win3.1, Win95 and Win98

    Note-
    the date and time are the date and time when I downloaded the files to
    my system, not the date and time of the file on the Lenovo site.

    Also beyond what I remember, in the old codes he was required to have a card encryption on tunnel and physical interface, but now is not.

    Since we use GRE over IPSEC, so for the verification of the tunnel I'll do the following steps:

    (1.) to check if the tunnel interface is in place. "show ip int br".

    2.) check if the statistics of tunnel are increasing and packages are browsing through it. 'show interface '.

    3.) check if crypto ACL includes only interesting traffic listed as GRE counterparts.

    (4.) If Yes, check the IPSEC Security Association statistics. "See the crypto ipsec his."

    If all of them are correct statistical evidence with respective counters increase traffic is passing by GRE and then by wrapping in IPSEC.

    I hope this helps.

    Kind regards

  • Somehow my XP OS some features to go home, but have always some quirks: the function of automatic update is on but a prompt warning burst to say computer is in danger and that the automatic update is disabled...

    I have been in contact with Avast and they got my antivirus works then it has eliminated some of the infected files, but has done some damage to my XP system. Now, as mentioned, I can do things that my previous question. I can't use my cd to repair XP due to a prompt to say that my laptop is a version higher than the cd update...
    Back to the drawing board. Any advice? An Apple MacPro is perhaps in my near future...

    Thanks to all of you who have read my problems.

    Well, that would be good...  If your system has installed Service Pack 3 (you did not) and your XP installation CD has an older PC, you probably want to use your old CD to repair your current system, would you?  Does this sound like your situation?

    Unless you have created an installation CD of new/updated XP with SP3 on it yourself, it is unlikely for most people to have such a thing.  You can certainly use your old XP CD to create a new installation CD of XP that has SP3 on it, but you can do it later (this is a fun project).

    So far things are working perfectly!

    Avast! sometimes has a bad habit of quarantine (effectively Delete) critical XP system files...  This is not sound like the problem with your automatic updates, but it would be nice to let some other scanners to look at your system (Avast! don't know everything).

    Since you seem to have had some kind of infection of the system, I suggest you do the following tests in addition to your Avast! and THEN solve any problems the scans by operating clean.

    Download, install, update and do a full scan with these free malware detection programs:
    Malwarebytes (MMFA): http://malwarebytes.org/
    SUPERAntiSpyware: (SAS): http://www.superantispyware.com/
    They can be uninstalled later if you wish.
  • ADAPTER DOUBLE BAND ONLY SHOW THE 2 GHZ RANGE, HAVE LOST 5 GHZ BUT PRESENT ON ALL OTHER PCS

    I inadvertently "REMOVED" the recognition of 'network' of 5 ghz on a menu that allowed me to "remove unnecessary networks."  I thought I was doing the right thing, but deleted by mistake the 5 ghz. Now I just can't side 5 ghz of the card to show as an available network when I click available networks at the bottom right of my screen.

    My dual band router LInksys is certainly put 2 and 5 ghz because I can see them on other PCs in the House and my Iphone6. It's only the HP All In One which now lacks the recognition of 5 ghz.

    It was working fine before my despicable act. I could easily switch between 2 ghz or 5 ghz...

    I rebooted router and reset I can see the 'admin' menu for the router on this computer.  I restarted my HP. I tried to restore my pc soon, and no effect. It seems that somehow I just simply deleted a vital statement or turned a vital switch that prevent this receiver WiFi HP-receive adapter or by switching to the 5 ghz range and the value by default only the 2 ghz.

    My system details also show that it is a working adapter RALink 3290 80211 bgn

    Is there a way to turn this back on? How do I re - establish the 5 ghz network on this HP?

    Any help out there?

    You are the very welcome.

    That is right.  No 'a' doesn't = No 5 GHz.

    I can't explain why you thought you saw other 5 GHz networks on your PC.

    The only wireless networks that should be visible on your PC are only in the 2.4 GHz band, because it's all Ralink card in your model can see.

    You might be able to replace the card with a wireless card dual band but I can't say for sure.  Some PC have a BIOS lock that prevents users from installing a different wireless card.

    You would have to make sure your PC has two antennas connected to the current Ralink wireless card because all dual-band cards have at least two terminals of the antenna to connect to.

    I would say the best thing you can do would be to go to your local office supply store and pick up a wireless network adapter dual band USB external.

    They now power USB wireless adapters, so you can get one of these.

    You wouldn't have any compatibility or hardware issues with an external USB card and not worry about BIOS locks or the number of antennas inside your PC.
