Allow the Ipsec Protocol in ISP

• Need for visibility on the IPsec protocol: aggressive Mode

  Hello

  I have a few doubts about VPN. I already went through a large number of documents. Everybody says something I don't agree with. So please don't view this kind of material in your answer.

  Aggressive mode: what I know, there are 3 Exchange for aggressive mode. Initiator in the first message sends the ID parameters, DH, HIS (IP address, domain name FULL). Then the answering machine (2nd MSG) reacts with the SA settings, DH, ID, HASH_R, then the initiator (3rd MSG) responds with HASH_I and PHASE 1 is established here.

  As the initiator and the responder IDs are sent in clear text, so we say that aggressive mode is not course.

  DH is used to exchange keys between peers. DH, negotiates and then generate a SECRET_KEY which in turn, is used to encrypt the symmetric key. We have SA parameters for encryption, hash, authentication.

  Here are my questions:

  (a) all of ITS parameters, IDs, DH traded first and second messages. The third message from the initiator is to send to HASH_I. Now, I don't see at all any use of DH in this mode, no encryption (payload ISAKAMP is not encrypted).  A single phase 1 aims to build a secure layer of management so that the PHASE connection 2 (data connection) may establish under a secure layer (PHASE 1). Now, I see that in aggressive mode we are not able to achieve this secure layer. So, what's the point of having encryption algorithms and DH in PHASE 1 if they are never used? Instead of skip PHASE 1 and we can have the PFS in Phase 2 for serving as a DH and we were hashing algorithms, encryption too.

  (b) the PRE SHARED KEY is actually shared via connect using the DH? Or just a HASH of PRE-SHARED-KEY is generated and sent on the connection for authentication?

  (c) why the aggressive mode can be used for dynamic addressing and not the main mode?

  If please answer queries and correct me if I am wrong somewhere.

  Thank you

  Rakesh Kumar

  (a). theoretically, jumping Phase 1 and done everything in Phase 2 (for aggressive mode only) would probably be a good idea to make it safer.  However, this would require a complete redesign of the IKE protocol.  As you probably already know, aggressive mode is used by default only for VPN remote access, and I've never seen used for a site to any of the customers that I came in contact.  In aggressive mode, in my opinion, would be used only in situations where a large number of VPN tunnels are built and demolished all the time (as with RA VPN) to save on material resources.  But... It is what it is, not a very safe to use method.

  (b) the pre-shared key is used to create a hash and this hash is sent to the remote peer.  If the remote peer can create the same hash using its own pre-shared key, then peers know they share the same secrets.  The problem with aggressive mode is that the hash is sent in plain text format, so if an attacker is able to capture these data they could preform a brute force offline attack.

  (c). I think that this has to do with the fact that the aggressive mode sends its identity in text clear and not must therefore not be pre-configured as a peer answer as it does with tunnels with addresses static at both ends.

• ACL to restrict the SCP Protocol

  Dear Sir

  I want to allow the SCP Protocol on my Cisco devices (routers, switches, wap,...) for a single host (a server that backs up the configuration by SCP).

  But if I'm not mistaken, the SCP Protocol through the SSH protocol.

  So, do you know if it is possible to allow the SCP to a host protocol and allow an SSH connection from any host using an ACL?

  Thanks in advance for your help.

  Kind regards

  Access lists filter network traffic by controlling whether routed packets are forwarded or blocked at the interfaces of the router. Your router examines each packet to determine whether to send or drop off the package, based on the criteria you specified in the access lists. Access lists can allow a host to access a part of your network and prevent another host to access the same area

  Hello guys,.

  I have Cisco ASA5520 facing the ISP with private IP address. We don't have a router and how to get the IPSec VPN through the internet?

  The question statement not the interface pointing to ISP isn't IP address private and inside as well.

  Firewall configuration:

  Firewall outside interface Gi0 10.0.1.2 > ISP 10.0.1.1 with security-level 0

  Firewall inside the interface Ethernet0 192.168.1.1 > LAN switch 192.168.1.2 with security-level 100

  I have public IP block 199.9.9.1/28

  How can I use the public IP address to create the IPSec VPN tunnel between two sites across the internet?

  can I assign a public IP address on the Gig1 inside the interface with the security level of 100 and how to apply inside to carry on this interface?

  If I configure > firewall inside of the item in gi1 interface ip address 199.9.9.1/28 with security-level 100. How to make a safe lane VPN through this interface on the internet?

  I'm used to the public IP address allocation to the interface outside of the firewall and private inside the interface IP address.

  Please help with configuration examples and advise.

  Thank you

  Eric

  Unfortunately, you can only complete the VPN connection on the interface the VPN connection source, in your case the external interface.

  3 options:

  (1) connect a router in front of the ASA and assign your public ip address to the ASA outside interface.

  OR /.

  (2) If your ISP can perform static translation of 1 to 1, then you can always finish the VPN on the external interface and ask your provider what is the static ip address assigned to your ASA out of the IP (10.0.1.2) - this will launch the VPN of bidirectionally

  OR /.

  (3) If your ISP performs PAT (dynamic NAT), then you can only start the tunnel VPN on the side of the ASA and the other end of the tunnel must be configured to allow VPN LAN-to-LAN dynamics.

  First of all, there is overlap crypto ACL with the VPN static L2L:

  crypto ASA1MAP 10 card matches the address 101

  access-list 101 extended allow ip 10.10.10.0 255.255.255.0 172.18.0.32 255.255.255.240

  I would remove the 2 lines of ACL 101 above because it is incorrect.

  Secondly, from the output of ' cry ipsec to show his ", you seem to be getting the ip address of the"jdv1.australis.net.au", not"CorpVPN"pool pool. Therefore, the No. NAT ACL on the management interface is incorrect. I would just add a greater variety of education no. NAT so that it covers all your ip pool:

  access-list no.-NAT-DU-MGMT scope ip 10.10.10.0 allow 255.255.255.0 172.18.0.0 255.255.255.0

  Thirdly, even with your dynamic ACL 'OUTSIDE_cryptomap_65535.65535' crypto map, it only covers the 172.18.0.32/28, so I just want to add a wider range since it seems you get the ip address of the different pool:

  OUTSIDE_cryptomap_65535.65535 list of allowed ip extended access all 172.18.0.0 255.255.255.0

  Then I would disable the following group of access for purposes of test first:

  no access-group MANAGEMENT - OUT Interface MANAGEMENT

  Finally, please clear all the SA on your ASA and xlate, then reconnect to your vpn client and test it again:

  delete the ipsec cry his

  clear the isa cry his

  clear xlate

  Please let us know how it goes after the changes. If it still doesn't work, please please send again the last configuration and also to send the output of the following:

  See the isa scream his

  See the ipsec scream his

  and a screenshot of the page of statistics on your vpn client. Thank you.

• How to prevent the FF loading all Web sites using the HTTPS protocol

  FF is trying to load initially all Web sites using the HTTPS protocol, including of mozilla.org. Then I get the error of no reliable connection of course. Mozilla .org is the "invalid security certificate" and "the issuer of the certificate is unknown." I tried to delete the file cert8.db as suggested elsewhere but that did not help. If there is an option for this somewhere, I can't find it. I have the latest version of FF and Win7 running. Thanks for the help.

  There must be some sites that are still using a secure connection, as http://www.amazon.com/. If even a link to Amazon is redirected, you can check if you have an extension like HTTPS Everywhere.

  For Mozilla sites, Yes, you establish a secure connection.

  But you shouldn't get certificate errors! When you get this for virtually all secure sites, the problem is usually as follows:

  (1) error of date, time, or time zone who throw checks validity of the certificates of your system. Sometimes allowing to use a timesource on the internet, the computers can introduce this problem.

  (2) not be set up to work with your security software that intercepts and filter secure connections from Firefox. Products with this feature include Avast, BitDefender, ESET, Kaspersky; AVG has a shield search function which can cause this error on search sites.

  (3) malicious software on your system for the interception of secure connections.

  So... who is?

  If you have any of these specific security products, which would be the first thing to check. We might be able to help with specific next steps based on what you have if you tell us.

  Alternatively, you can examine the certificate to which Firefox is opposed to see if the issuer information pointing to the culprit. Take for example my test page:

  https://jeffersonscher.com/RES/jstest.php

  You should see a section "I understand the risks" in the page. If you expand this section, you will find a button Add Exception. You don't need to complete the process of adding an exception (I suggest not adding one until we know that it is not a problem of malware), but you can use the dialog box to display the information that makes Firefox suspicious.

  Click Add an Exception, and then view. If the view is not enabled, try first the button get certificate. Then in the certificate Viewer, refer to the section "issued by". What do you find here, or under the hierarchy of certificates? I have attached a screenshot for comparison of screen.

• How to find the security protocol used by a site in firefox to version 24.6.0

  I'm unable to find the security protocol used by the site, either SSL or TLS 1.0 or 1.2.

  I see my answer above is marked as useless, so I guess it doesn't help for Firefox 24.

  You should be able to see which version of the TLS Protocol and encryption to agree to the current use of press.
  You can use the above posted extension or check in the Security tab of the Web Console (Firefox/tools > Web Developer).
  24 Firefox supports only TLS 1.0 (security.tls.version.max = 1), so that only leaves you with Protocol to guess.

  • http://KB.mozillazine.org/security.TLS.version. *
  • 0 means SSL 3.0, TLS 1.0 means 1, 2 means TLS 1.1, 3 means TLS 1.2 etc..

  In Firefox 24 you have the Security tab in "tools > Page Info > Security" to see what level of encryption is used, and you do not see what costume of encryption is used.
  To find you would have to disable any combination of encryption algorithm by setting the Pref security.ssls false and allow both until you get a secure connection.

• Canon printer does not connect via the IPP Protocol

  I work in a company that sells printers offices/schools/etc. Yesterday, we received a call from a customer indicating that the Copier, we sold them connected not to a new computer they bought.

  I went to the site and noticed that the computers in question were all purchased during 3 months and all loaded with Mac OS X El Capitan. Most was registered on 10.11.3, and some 10.11.2 and 10.11.1. All computers work turned Yosemite.

  We receive a message somewhere in the sense of "Communication error. This printer may not be able to [print], you want to save it anyway? »

  It was a cannon imageRUNNER Advanced C5235. The client declares that if he saved the printer, it would not be able to print, but would still see jams paper, messages and other statutes of the computer printer toner. After attempting to remove and reinstall the printer using the most recent driver available on the Canon Website, we received the same error, the customer received. We escalated it to Canon support, who asked us to choose LPD instead of the PPI for the Protocol, allowing the printer to you connect and start printing on all devices running El Capitan.

  After further research, to my knowledge, the ISB is more recent and has more features that the LPD, although I couldn't find much on it so I was uncertain about the origins of these two protocols, except that they were introduced in the 1990s. I know it's kind of vague, but is better/more recent than PPI LPD? If so, great. Otherwise, is there a way to solve this problem and get computers that run El Capitan to connect correctly using IPP?

  The problem here is that the driver Canon UFR2 or PS that was used on the Mac to print in ADVANCE of Canon C52xx does not support PPI. This is why you must use an alternative Protocol.

  Note that it is possible to print to the C5255 using the PPI, but you need to use the Canon PPDs which means the copier must have the kit installed Postscript printer and you get not the pretty picture base views the pilot UFR2 and PS to give you.

  Second point is that the Canon UFR2 and PS drivers, it is preferable to use HP Jetdirect-Socket to the LPD protocol. He sent larger packets and verifies the status of the target unit - LPD simply sends data to the fixed IP address so if the printer has a problem you don't get this information until you walk up to the photocopier.

  I hope this helps. Answer if you need more information.

• "The network adapter is not correctly configured to use the ip Protocol" problem on Vista

  Hello. My PC has recently came across this problem "the network adapter is not correctly configured to use the ip Protocol", every time I click on diagnose & repair. I don't know how to fix it. Please help, thanks in advance. Magic

  Hello X-x_MaGiC_x-X,

  Thank you for visiting the website of Microsoft Windows Vista Community.

  Try the rest of the stage in this article:

  System restore points are created automatically when the following occur:

  • When you install a new application or driver.
  • When you uninstall or install some programs.
  • When you install new updates
  • Automatically on a daily interval
  • Manually by creating a.
  • If you choose to use system restore to restore to a previous restore point, System Restore creates a new restore point before you restore a previous state in case something goes wrong. If you are restoring to a previous state in Mode without failure, a restore point will create for the current state.

  So that the restoration of the system to work, you must have 300 MB of free space for each hard disk that monitors the system restore. System Restore will also use up to 15% of disk space on each disk that it monitors. That hard disk space runs out, older restore points will be deleted as newer ones. It is also important to note that you must be logged in as an administrator in order to use the system restore. Now that you understand the basics of the system restore, you must continue to the next section to learn how to use it.

  Restore Windows Vista to a previous state

  In the case of a problem on your computer that cannot be solved by normal means, you can restore your computer to a previous working state. To do this, you need to start restoring the system so that you can choose the restore point to restore. If you currently have Windows Vista boot problems, you can use the system restore in Windows recovery environment. Instructions on how to do it in this tutorial can be found: System Restore using the Windows Vista recovery environment.

  If you can connect to Windows Vista, you must follow these steps.

  1. Close and save any documents that you have opened.
  2. Click the Start button to open your Start Menu. The Start button looks like this:
  3. When the Start Menu open click on the menu option all programs.
  4. Click once on the Start Menu Accessories group.
  5. Click once on the System Tools Start Menu group.
  6. Click once on the icon of the system restore. After you click the icon, if a user account control window opens, click on the button continue.

  You will now be on the screen as shown below in Figure 1 system restore. From this screen, you can specify the restore point that you want to restore.

  1 screen of system restore

  By default, Vista will be already selected the restore recommended option. This restore point is one followed a new pilot program, or update has been installed. If you do not want to use this restore point, you can click on the button next to start the restore process. On the other hand, if there is a more recent restore point that you want to restore you should select choose a different restore point and press the next button. This will bring you to a screen, as shown in Figure 2, which contains a list of all available restore points that you can restore.

  2. the list of available restore points

  You must select the restore point that you want to restore, and then press the button next to start the restore process. Vista will display a window showing your selected restore point and asking you to confirm that it is that you want to restore.

  3. confirm the selected restore point

  If you want to select a different restore point, press the Back button. Otherwise, you can press the Cancel button to exit the system restore or the button finish to begin the restore process. If you have selected finish, Vista will display a second prompt asking you to confirm that you want to continue restoring.

  4. second Confirmation

  If you are sure you want to restore, then press the Yes button. Vista will now log you off the computer and start the system restore process, as shown in Figure 5 below.

  5. restoration of a restore point

  When the restore is complete, your computer will be restarted and when Vista starts it backup will be restored to its previous state. When you open a Vista session for the first time after the restore, you will see a message indicating that the restore was successful.

  6. system restore was successful

  If there are problems with your computer because the last restoration, you can return to your previous settings to ebb in the system restore utility and select Undo system restore by pressing the next button.

  7 undo the last system restore

  Your computer should now work correctly again.

  With the help of the restoration of the system in the Windows recovery environment

  Manual creation of Restore Points

  As mentioned previously, it is also possible to create manual restore depending on points. Some popular designs to create manual restore points are when you have your computer configured perfectly and I would save the State in case of problems in the future. To create a manual restore point, you must follow these steps:

  1. Click the Start button to open your Start Menu. The Start button looks like this:
  2. Click on the control panel menu option.
  3. Click the option menu system and Maintenance.
  4. Click on the system menu option.
  5. Click on the System Protection in the list on the left.

  You will now be at the System Protection tab in the system control panel. This tab allows you to enable and disable the system restore as well as making the new manual restore points.

  8. the System Protection tab

  To create a manual restore point, you must click on the button create. When you press this button a prompt asking you to give a title to this manual restore point.

  9. Enter the manual restore point title

  Type a title for the manual restore point and press the button create. Vista will now create a restore point manually and once finished, post a notice that it was created successfully.

  10. Manual restore point has been created

  Now that you have finished doing the manual restore point, you can close the system window.

  Try to download the correct and up-to-date drivers.

  This should solve your problem.

  Let us know if these steps solve your problem.  I hope the information is useful.

  Kind regards

  This may be a better response https://learningnetwork.cisco.com/welcome, but Q in Q is actually a framework with two headers tag VLAN.  It is often used with L2 MetroE providers.  It allows the provider to have their own separate VLANs for VLAN client running on their network.  For example, on the MetroE provider VLAN 5 network contains all customer traffic VLAN 6 x contains all clients traffic Y, again customer X and the customer is using several VLANS, possibly including VLAN 5 or 6.

• Help: Adding to the IPsec Tunnel encryption field Questions

  Good evening everyone,

  I'm looking for help and/or advise in what concerns adding more networking in the field of encryption of an existing IPsec site-to-site tunnel.  Both sides of the tunnel are of ASA.  The client on the remote end is eager to access the networks more on my end.  They have already updated their ACL crypto map to include the new networks.  When they perform "show crypto IPsec his counterpart x.x.x.x" it shows already encap packets attempting to join my network.

  On my side, I updated my ACL crypto map to reference the new 2 networks, created the double NAT and added the ACL needed to allow the inbound access through ports they want.  When I perform a 'see the crypto IPsec his counterpart x.x.x.x' output is NOT up-to-date with the new networks added to the field of encryption.  When I run a tracer of package of supply of one of the servers in the new network, the traffic is translated as he should, but a fall when it hits the outgoing interface for the VPN tunnel.

  Am I missing something here? Can I bounce the tunnel so that the new networks must be recognized in the surveillance society?

  Thanks in advance.

  Hello

  You must bounce the tunnel when you change the interesting traffic, otherwise the new SA will not be created, is a little funny that you say that SA is already build on the remote side, SA cannot be established only on one side, is like building a new tunnel, if you don't have it on one side, it can not simply prevail and create the entry of SA. In addition, adding new networks and bounce the tunnel you need to generate traffic to trigger the ITS new or you will never see that it created. Check your no nats and routing and it should work.

  Best regards, please rate.
