• IPSec with Cisco 819 G (license)

  Hello

  I'm trying to configure IPSec on a Cisco 819 G. According to this document ( http://www.cisco.com/c/en/us/products/collateral/routers/800-series-rout... ), the SL-810-AIS (IP services) licenses and SL-810-ADVSEC (Adv security) are included by default.

  However, Adv security is not enabled:

  Do you know how is it possible to get activated in order to be able to configure IPSec?

  Thank you

• IOS router VPN Client (easy VPN) IPsec with Anyconnect

  Hello

  I would like to set up my router IOS IPsec VPN Client and connect with any connect.
  Is it possible to configure an IPSec and SSL VPN Client on IOS router? I use for example a 1841.

  It would be perfect to give the user the choice of SSL or IPSec protocol. And the user needs that the Anyconnect Client.

  I think it's possible with a Cisco ASA. But I can also do this with an IOS router?

  Please let me know how if this is possible.

  Also is it true that the IOS routers are not affected to hear bug bleed? SSL VPN and SSL VPN with Anyconnect page is also save?

  http://Tools.Cisco.com/Security/Center/content/CiscoSecurityAdvisory/CIS...

  But I am in any way interested in using IPSec and SSL VPN on a router IOS...

  It's true - CCP does not yet offer the options to configure a VPN IPsec with IKEv2.

  The configuration guide (here) offers detailed advice and includes examples of configuration.

  I tried ISA550 a config with the same constelations, but without suggesting.

  Anyone has the same problem?

  And had anyone has a tip for me, or has someone expirense with a site-by-site with ISA550 and Cisco 2821 ipsec tunnel?

  I can successfully establish a tunnel between openswan linux server and the isa550.

  Patrick,

  as you can see on newspapers, the software behind ISA is also OpenSWAN

  I have a facility with a 892 SRI running which should be the same as your 29erxx.

  Use your IOS Config dynmap, penny, you are on the average nomad. If you don't have any RW customer you shoul go on IOS "No.-xauth" after the isakmp encryption key.

  Here is my setup, with roardwarrior AND 2, site 2 site.

• IPsec VPN with Cisco AnyConnect and 1921 ISR G2 router

  Hello

  Is it possible to establish a remote access VPN IPSec using Cisco Anyconnect client with router Cisco ISR G2 1921.

  If someone does share it please the sample configuration. as I've been on this topic since last week a.

  My Cisco rep recommended I have not try AnyConnect a router ISR or ASR.  So I used an Open Source client.  Don't say that AnyConnect won't work, just the route I took on my project.  I work good known configuration for a 1921 with strongSwan as a Client.  It is with IPSEC and IKEV2 using certificates for authentication.

• LAN-to-LAN tunnel between VPN 3000 and Cisco 1721

  Hello

  I have a current LAN-to-LAN tunnel configuration between VPN 3000 (3.6) and Cisco 1721 (12.2 (11) T).

  When I use the encryption = authentication and Des-56 = ESP\MD5\HMAC-128 for the IPSec Security Association, everything works fine.

  However, I would like to Turn off encryption for some time getting the speed improvements, so I changed

  Encryption = null esp (in 1721) and to "null" in VPN-3000.

  Now the tunnel is setup but I can spend only ICMP traffic. When I pass the traffic UDP\TCP the message below appears the Cisco 1721

  % C1700_EM-1-ERROR: error in packet-rx: pad size error, id 75, hen offset 0

  Has anyone seen this behavior?

  All those put in place an IPSec Tunnel with only the ESP authentication and NO encryption between VPN-3000 and Cisco 1721?

  Thanx------Naman

  Naman,

  Disable you the vpn Accelerator? "no accel crypto engine. Sure that you can't do with a null module vpn.

• AnyConnect + possible PSK (pre-shared key) as under with cisco vpn client ikev1 and ikev2

  Is it possible to create a VPN Anyconnect of RA with just the name of user and password + pre-shared key (Group) for the connection, as could do for ikev1 with cisco VPN client? I am running 8.4.X ASA code and looks like tunnel-group commands have 8.2.X somewhat change. If you change the group type of the tunnel for remote access, now there is no option for IKEv2 PSK.

  I'm getting old so I hope that it is not in another complaint curmudgeonly on the loss of functionality. :)

  Many small businesses do not want to invest in the PKI. It is usually a pain to deploy, backup, make redundant, etc..

  But it would be nice to have a bit more security on VPN other than just the connections of username and password.

  If this is not possible, it is possible to configure the Anyconnect customer to IKEv1 with PSK and name at the level of the Group client?

  If this is not possible, WTH did cisco end customer VPN cisco as a choice of VPN connection (other than to get more fresh mail of license)?

  I really hope that something like this exists still!

  THX,

  WR

  You are welcome

  In addition to two factors, you can also do double authentication (ie the two using the user name and password). Each set of credentials can come from a Bank of different identities.

  With this scheme, you can can configure a local user name (common) with password on the SAA (think of it as your analog PSK) and the other be the AD user identification information.

• need help with VPN IPSEC with RV042

  https://supportforums.Cisco.com/docs/doc-30883

  I enjoy any support for a trial with RV042 VPN IPSec game please.

  Thanks in advance.

  Hi Bay, if you use a Windows computer, you can use QuickVPN. The only thing to note is the router that you have as the gateway to the RV042. You must define a port forward for all IPsec services be able to overcome the problems with the NAT device.

  RV042 configuration is easy, create a name of user and password and that's it. The problem/challenge will get your NAT connection to allow VPN pass.

• Authentication IPSEC with CA

  Hello

  During the configuration of IPSEC with CA authentication. We have to install two certificates on ASA - identity certificate and the certificate of the CA. I did not really understand these notion of certificate of towing.

  Please share the experience of any explanation link / URL is very significant.

  Attach here the Cisco document that we are referring to the configuration.

  (This paper shows the installation of these two - identity and CA certificate).

  Thanks in advance.

  Subodh

  2 certificates are different things-

  (1) identity certificate identifies the real device. So when your firewall implements one VPN with another firewall identity certificate is that your firewall uses to identify itself.

  (2) the CA is a certificate issued by a certification authority (CA). This CA can be a public CA such as Versign, or it can be your own internal CA.

  The idea behind a certification authority is that someone should be able to tell if a certificate is valid or not. So when your firewall sends its certificate of identity to a 3rd party how this thrid party knows he sent certificate is valid and is your firewall. Here comes the CA.

  Basically a public CA such as Versign act as an independent body that says whether or not identity certificates are valid. Of course, this means that all parties must trust Verisign. When the 3rd party firewall receives your identification certificate it will be a string of included certificate that will point to Verisign. If the third-party firewall then can "ask" If Verisign certificate is correct or not.

  I don't know, but probably this was not yet supported 12.4.

• My computer is infected with virus/bug I have checkd with Anti virus few records showed infected but could not remove.

  My computer is infected with a virus/bug I have checkd with Anti virus few records showed infected but could not withdraw, step by step programs stoped working, I tried all the things microsoft Web and other webs to run antispy etc, but nothing works programs start, but halfway to display error and stop now even explore stop working, now I had a white windoa screen opens more but I have a lot of data that is important, how to fix it? can anyone help please thanks

  Raz2009,
  If you have a known problem with the virus then I suggest to get an antivirus program that you can boot from and run it without starting Windows.

  Another option would be to format your drive and do a clean install of Windows (this would remove all the data of your drive).  If you have a backup of your data, this is the best course of action.  If you do not have a backup, you can then do a parallel install (This installs XP in a different folder if you don't lose any data). Here is an article on installation options: http://support.microsoft.com/kb/316941

SLM2024 and WAG320N work perfectly, the statistics showed no loss of packages of Ant conflicts... but any computer (win 7) lost access to the internet, otherwise access to the local network.
