• Any bug IOS (ADSL + IPSEC) with Cisco 1721?

  Hello

  I tried to install an IOS image with support ADSL and IPSEC on a Cisco 1721.

  When the router works fine with ADSL, it does not work with IPSEC and vice versa.

  I tried to change the router with a similar 1721, but nothing has changed.

  I tried the following images (I found them with IOS Scheduler) for IPsec:

  C1700-o3sy756i - mz.121 - 3.XP3.bin

  C1700-o3sy756i - mz.121 - 5.YB5.bin

  When I install the versions of IOS, I can't see the ATM interface.

  Have you noticed any IOS bug related to ADSL + IPSEC with the Cisco 1721 versions?

  Thank you

  Paolo

  Hi Paolo

  It comes to the interface card WIC ADSL is not supported in versions of software you tried.

  According to "Software Advisor", the card WIC-1ADSL is supported on the platform of 1721 in the following versions:

  12.2 (13) T, 12.2 (4) AGO, 12.2 (4) 12.2 (4) YH, YJ 12.2 (8), YL 12.2 (8), YM 12.2 (8), YB, YN 12.2 (8)

  So, you will need to get a new image, a crypto of the cause.

• 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.

• Single Sign on authentication failed with error [user: username is found, but]

  Hello
  
  URGENT:
  
  One user is trying to connect to Essbase by Excle worksheet. To connect in Essbase, this user who connects to the network using the VPN connection. I suspect that this question arises because of an invalid password, but the user claiming that password is correct. When I checked the user information in Essabase, he gave an external authentication that is valid.
  
  Please help me on this issue. What should go wrong with this user?
  
  * Single Sign on authentication failed with error [user: username found, but could not authenticate] *.
  
  Thanks again for your help.
  
  Kind regards
  UB.

  If essbase uses an external authentication as MSAD, you can get the password changed at the level of the AD by someone who takes care of the administration.

  See you soon

• Unable to set authentication of IPSec with RADIUS clients

  Hello

  I configured the VPN IPSec server for remote clients on Cisco 2811 with XAuth (see attached cisco vpn configuration). Initially, I configured clients extended authentication (Xauth) using a local database of IOS users and it worked fine, but then I tried to configure the authentication of clients through FreeRADIUS and got authentication errors (see part of freeradius log attached): in fact, instead of username/password name customer shipped Xauth Cisco sends a VPN-group/pre-shared key combination to FreeRADIUS. Obviously FreeRADIUS does not name of user and password in its database and answers with an error. Is it possible somehow to reconfigure Cisco such that it would be sent insead of name of user and password to VPN-group/pre-shared key or reconfigure FreeRADIUS so that he would interpret the VPN-group/pre-shared key parameters?

  xauth to the radius server must be not sending the group name and the password to the RADIUS. xauth should send the user name and password when the user authenticates.

  (1) you can try to authenticate to the server radius of the router itself, using the command 'test aaa'--> check if authentication works.

  (2) when you connect with the vpn client, you get prompted for the user name and password, and what do you have?

• Dynamic to static IPSec with certificate-based authentication

  I'm trying to implement a dynamic to static LAN2LAN vpn from an ASA 5505 (with a dynamic IP address) to an ASA5520 (with a static IP address)
  I wish I had a small (/ 30) network on the side dynamics which I can connect to a larger (/ 24) network on the static side.
  I also try to use the identity for authentication certificates.

  I produced a root and intermediate CA signed of the intermediate CA with the certificate authority root and then created identity cases for
  the ASAs, signed with the intermediate CA using OpenSSL and imported to a trustpoint

  I tried to use the instructions on:
  http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a0080930f21.shtml
  to configure certificates (replacing MS with OpenSSL) and following the instructions to:

  I tried the ASDM to set up the cert to identity appropriate on the external interface
  [Configuration-> Device Management-> advanced-> SSL settings]

  and establish a connection profile [Configuration-> Device Management-> connection profiles] on both devices,
  setting the part that gets its IP via DHCP static and the side that has the IP permanently to accept dynamic.

  I apply the settings, and nothing happens.

  See the crypto isakmp just returns "there is none its isakmp.

  I don't know where to start debugging it. How can I force the side DHCP to initiate a connection?

  We are sure that both peers are using the same isakmp settings? It seems the policy that uses rsa - sig on one end uses a different Diffie-Hellman group.

• Problem creating a VPN IPSec with SRP527W

  Hello.

  I have a Setup like this:

  192.168.15.0/24 SRP527W <->internet <->ROUTER [172.16.16.1] <1:1 nat="">pfSense (raccoon vpn server) [172.16.16.2] 192.168.55.0/24

  I set up a VPN between the SRP and pfsense connection but the connection is not established because that timeout of the phase 1. According to racoon on the remote side does not.

  Before that, I've properly established a VPN between the SRP and another box of pfsense, but with a public IP address. The same host, I have an another vpn to the pfsense box (172.16.16.1) works correctly.

  These parameters of the PRS:

  IKE policy:

  Exchange mode: aggressive

  Permit ID: manual

  Remote ID: 172.16.16.2

  Encryption: 3DES

  Authentication: MD5

  DH: Group 2

  Remote end point: IP ADDRESS

  IP: 172.16.16.2

  Life expectancy: 7800

  Set local subnet and remote according to the above (192.168.x.x) Network Setup.

  How can I check what is the problem? I struggled for several hours now and have failed to go out again! Any help really welcome!

  Thank you

  Lorenzo,

  The router to 172.16.16.1 allows all traffic to the pfsense VPN server when specific NAT is enabled or you have create access rules? My guess is that the router is blocking the traffic.

  Unfortunately, as you have understood well enough already, XAuth is enabled at the global level, not by group. If you turn it on for some users, it gets turned on for all, no way around it.

• Authentication IPSEC Client tunnel computer

  I'm trying to convert our access existing distance from Microsoft Threat Management Gateway Cisco ASA.  Our security people just made me aware that in addition to the Radius authentication against powers AD they want as machine authentication to make sure that the computer name of the system trying to get remote access has a machine account in AD.

  I have been looking for a way to do it with the client IPSEC but you have not found anything yet.  Would appreciate links that show me how to do to get there.  Anyconnect moving is not an option at this point because of budget problems.  I use the latest version of the Cisco VPN client on the train 5.x and 8.2.5 code that runs on my 5520.

  I can watch maybe NAC (Network Admission Control?).  Looking for any suggestions at this point.

  Thank you

  Ron

  I used certificates X.509 USER registered with Cisco VPN Client 4.x / 5.x in an ASA. They are issued by the CA root of the partner and the connection has been authorized on the basis of this root CA being approved by the ASA remote.

  But yes, what you're asking about more than a NAC or the successor to the type of engine service identity (ISE) feature product. In the case of ISE, it can do what you ask, but requires a good bit of investment to get this and many many more features.

  I strongly suspect that some additional investments will be needed to get that request your security team. At least AnyConnect Premium licenses and use of the functionality of the access network (NAM) Manager. See this reference.

• Problem with tunnel IPSEC with NAT

• Authentication problems with PEAP WLC IAS Windows 2 k 3

  Hi all

  I configured a WLC (6.0.182.0 model 2100) with authentiacion PEAP with IAS and DA of Microsoft Windows 2003. I read in the documentation "PEAP under Unified Wireless networks with Microsoft Authentication Service IAS (Internet)" in the process of installing Active Directory, it must select the "Permissions compatible with operating systems prior to Windows 2000 server". In my scenario the other option was selected "Permissions compatible only with Windows Server 2003 operating system or Windows 200".

  I test this scenario and it does not work.

  Is there a configuration in the WLC so that it can operate without having to reinstall the AD?

  Thank you

  In most cases the WLC does not care about the type of authentication is used. It's really just the transmission by proxy requests between the client and the Radius server.

  I'll make sure that your timer EAP are extensive with the commands:

  Advanced Configuration eap identity-request-timeout 10

  You should also check wireless downloads. In the area where you can find the code of the controller to download, you can also find a 'Wireless LAN Controller Web authentication Bundle' containing several samples of html, including e-mail data.

  This link might work, maybe not:
