name of the site 2 site tunnel (peer IP) must match on both sides?

Hello.

I'm trying to set up some private networks virtual site 2 site between 3 offices using 3 cisco ASA 5505.

In the manul to these ASAs, it is said that when you set up the connection (I use ASDM and the wizard of easyVPN) it is said that when you use a PSK for authentication between the two sites, the name of tunnel must be the IP address of the peer. Is it OK so far?

Because I always thought that the names of the tunnel must be identical on each side. So it means that the site one tunnel name will be site of 2 IP address while on site 2, the tunnel will be the IP address of the site from 1. Is this correct? As I said I always thought that the names of tunnel should match the other.

Also, can someone tell me if this configuration works.

I have 3 sites that I want to put in a mesh VPN site2site scenario.

So basically, I have 3 routers. And on each router, there will be 2 site2site tunnels configured (via easyVPN ASDM) for the other 2. This sound is feasible? And if so, the names of tunnel for each connection on each router will be the IP address peer?

Appreciate any idea.

Hi Matthew

Tunnel name musnt/beveled or even on the two sites. Only IP address peer and tunnel-group must be same to site A.

Lets say that the site will allow you to create a VPN as follows

A B - C

An interface IP = x.x.x.x site

Interface of the site B IP = y.y.y.y

Interface of the site C IP = z.z.z.z

Thus, in the ASA in site a.

tunnel-group y.y.y.y type ipsec-l2l

xmap 10 crypto map peer set y.y.y.y

ASA in site b.

tunnel-group x.x.x.x type ipsec-l2l

xmap 10 crypto map peer set x.x.x.x

tunnel-group z.z.z.z type ipsec-l2l

card crypto xmap 20 peers set z.z.z.z

ASA in site C

tunnel-group y.y.y.y type ipsec-l2l

xmap 10 crypto map peer set y.y.y.y

  • Buttons to sites that adopt the name of the site

    Hello. I made a bar by myself.

    Bildschirmfoto 2015-07-07 um 17.23.43.png

    Is it possible that the text of the buttons is bound in the name of the site on which is connected to the button?

    For example, if I change the title of the "Portable RADIO" to "BLABLA" subsite and editing text of "Portable RADIO" to "BLABLA" button too.

    And is it possible to do this "HOME / EXPENSE / portable RADIO" with a menu bar that hides the subsite "Portable RADIO" if I'm on the site above (EXPENSE)?

    Menu by default will include the name of the page that you have configured in map mode, you can use the menu manual and add names with link menu items to their corresponding pages.

  • How to change the word "HOME" on the tab to the name of the site?

    Hello

    I was wondering if there was an easy way to change the word "HOME" on the tab to the name of the site? the bit next to the favorite icon?  Any help is greatly appreciated

    In outline, it is enough to double-click the label beneath the thumbnail of the homepage and rename.  If you use an auto-menu of Muse, which renames all the links too.  This may or may not be what you want to accomplish.

    Another option is to open your page (s) Master, go to Page > Page Properties > metadata and enter your text to the title of the Page title prefix.  This text will appear in the tab before the page for each page name to that Master Page is applied.  This is a good option if, for example, you want your name or business name appear on each tab.

    Or, open a Page-master, go to Page > Page Properties > Options and use the name of the Page and the title of the Page.  Try it to see how they behave.

  • File name of the Image displayed in PSE 8 does not match the file path name in Windows 7

    I recently got a new computer. I've updated on my computer Windows XP of PSE 5.0 to 8.0 PSE.  Then, I moved my files to the new computer that is running Windows 7, following the instructions that I have received on a previous post.  I copied the catalog file and the image files on the C drive of the old computer to the new computer (file catalog to the specified location in the information system;  images of my images).   Everything seems to have worked beautifully without having to go through a great struggle to reconnect.  The organzer seems to have found all of the images and I can put them in the editor as well.  However, when I look at the properties of a given image displayed full file name is that it was on XP: C:\Documents and Settings\ < username > \My Documents\My Pictures\ < folder name >-< Filename > rather than the path as it is in Windows 7, i.e. C:\Users\ < username > \My Pictures\ < file name >-< Filename >.  I am new to Windows 7 then maybe miss me something unique to Windows 7 but I'd like information.

    You are using the alias of the special folder that Vista and Windows 7 create to maintain backward compatibility (Microsoft continues to change how and where are stored the documents of users).   On Windows 7:

    C:\Documents and Settings\\My Documents\My photos

    is a special type of alias in the file:

    C:\Users\\Pictures

    (AndC:\Users \My Pictures is yet another kind of Windows 7 special alias, a 'library', which includes the folder C:\Users\Pictures.)

    Whenever an application like PES refers to the old location, C:\Documents and Settings\\My Documents\My photos, Windows that automatically converts backstage in C:\Users\\Pictures.   But Windows Explorer is configured to prevent you to access C:\Documents and Settings\ interactively - only programs like PES are able to do.  Microsoft wants users of Windows Explorer to always use the name of 'new', C:\Users\\Pictures.

    In your case, your catalog contained the old paths of XP folder, and Windows is automatically translate on the fly for new paths, unbeknownst to PSE.

    Like most of the backward compatibility hacks, this does not work perfectly.  PSE believe that the old road and new road are two completely different cases.  I'm not positive, but I think that there are opportunities for PSE to get confused by that.   When you import new pictures, they get recorded in the Catalog under the new folder paths.

    In my previous recommendation about how to move to the new computer, I had assumed you would probably change user names and locations of photo and so you would have to make a reconnection, and you would not have met it.  If I thought that you were not have need to reconnect, I would have recommended not not using this method, but rather using Backup/Restore (my first recommended method) - my bad.

    It would be nice if your current catalog and the PES works pretty well.   But there is at least a small risk that the road of PSE will get confused by old and new folder names.  The best way to avoid this would be to start again and use the backup/restore method to move your catalogue, which is more effort on your part.  But because I do not understand the risk, I can't tell you if you should be worried about it.   No doubt do tests: editing, import and edition of new photos, use view > view of the location of the folder, try to rename and move the old photos and the new folders, try the Photo Downloader, etc.
