2901 router as an SSL VPN using
Hello world!
I was wondering if someone could give me a hand on this. I'm trying to use a Cisco 2901 to allow remote workers to access resources on the local network using the Client AnyConnect Secure Mobility Client. I just read this doco
http://www.Cisco.com/c/en/us/support/docs/routers/3800-series-integrated...
But it seems it does not support the 2901 platforms. I quote:
WebVPN or VPN SSL technology relies on these router IOS platforms:
870, 1811, 1841, 2801, 2811, 2821, no. 2851
3725, 3745, 3825, 3845, 7200 and 7301
Is that all just because this topic is old?
Before I have to spend money on the wrong license, I decided to give it a go (above the following article). So, when I went to
' Configure > Security > VPN > SSL VPN > SSL VPN Manager "CCP says I need license"(securityk9). I then followed the link "activate license" and clicked on the tab 'evaluation licenses. But where there are two that seems good:
- securityk9 (the CCP one says it needs)
- SSL_VPN (one who seems reasonable as AnyConnect uses SSL VPN, right?)
What is the license of right? Anyone can enlighten us please?
Also, is there any resource that explains better than all the options and how to configure the AnyConnect on a router ISR2, using CLI?
Thanks in advance
Alvaro
Hello Alvaro,
What IOS version you are using?
Beginning in Cisco IOS version 15.0 (1) M, the SSL VPN gateway is a licensing feature sits a count on Cisco 880, 890 Cisco, Cisco 1900, Cisco 2900 and 3900 Cisco platforms. A Chair does refers to the maximum number of sessions allowed both.
For more information, go through:

SSL VPN using core instead of configured Group group
I have a 3000 configured for Ipsec using ACS to authenticate users. I tried to add SSL VPN. I can authenticate and install the SSL client, but I can't access anything whatsoever. I am connected via the base group, explains the newspaper on the 3000. How can I get SSL to work via the group which I configured and not the core group?
You should be able to achieve this with your RADIUS server. You must set the class attribute 25 as an ORGANIZATIONAL unit name equal on behalf of the particular group you want to connect to on the hub.
For example, suppose you want a SVC_User user to connect to a group called SSL_VPN. In the configuration of the RADIUS user, you would (under the attribute 25):
UO = SSL_VPN;
(... Do not omit the semicolon.)

SSL VPN using ASA 5520 mode cluster - several problems
I configured 2 ASA 5520 s in the load balancing cluster mode. I connect using anyconnect and I download the customer the first time and everything works well except outlook. I don't know why outlook does not work.
The second problem is after the anyconnect client is installed on your machine, he remembers that ASA (say ASA2) he first connected and the GUI shows the address IP of ASA2 instead of the virtual IP address of the cluster. I want users always connect using the virtual IP address.
The third problem I have is there is a default group of SSL VPN and I want all users to use this group. In the initial web page, there is a drop down menu which shows that this group, but I still want to disable this menu drop-down.
Any suggestions?
To disable the drop-down menu, you can turn it off with the command
WebVPN
no activation of tunnel-group-list
This will take care of your last issue.
***************************
You can create a profile of the Anyconnect client with the name of the server you want to connect with and that make the ASA that will solve your problem of virtual IP.
**************************
Regarding Outlook, do you use specific ports which allows inspection of the ASA. Take a look at the list of inspection on the SAA and perhaps try to disable inspection and see if it works.

I work on the AnyConnect SSL VPN deployment and seeks to secure the connection with a certificate that is NOT provided by the internal CA of the ASA or a 3rd party. What I would do, is our domain CA (MS) approve the certificate - in this way, all users of portable computers that connect to the VPN will accept the certificate without asking for confirmation.
Is there any type of document from Cisco that describes this case? I looked at the Cisco configuration documents that show:
-install manually 3rd party SSL VPN vendor certs (IE. VeriSign)-to obtain digital certificates for a MS CA ASA (it emits only IPSec certificates for users - the lancers ASA an error on the EKU without specifying the role of authentication server)
-renew/install the certificate SSL with ADSM (applies only to the self-signed certificates)
-examined the anyconnect Administrator's guide
I found two similar positions in the community, but there is no answer from anyone whether or not this is possible.

I would be grateful for any feedback. I may end up copying the certificate self-signed ASA on all laptops users VPN: S
Greg
You treat the SSL VPN as a web server... Create a 3rd party application signing, load it onto your MS CA and select Web server profile... You will need the CA cert so the cert of identification. You load the CA cert first then the cert of the identity.
You then attach the cert to an interface.
I did it on my internal interface so that the customization pages would stop sent me some errors in my browser... I went with a cert of public own party 3rd for the external interface given that I expect no area machines to connect and telling users how to install certificates is a pain.

AnyConnect ssl vpn using digital certificates
people
I have an asa 5540 (8.4) used to stop vpn ssl connections
the device is used as a local certification authority and issued certificates to remote users and these are then used as part of the authentication process
I now have an obligation to replace the self-signed certificate and buy a third-party certificate, for example verisign etc.
can someone point me to a guide for the performance for this
can I still use the asa to generate certificates for guests to use as part of the authentication process
Thanks to anyone taking the time to answer or two reading this
greatly appreciated
http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a00808b3cff.shtml
is the guide to install 3rd party cert.
The local process of CA is independent of user certificate to authenticate the ASA, in fact, if you look at the CERT gives users that they are provided by the CA of the ASA and unsigned by cert used for authentication.
Take care of is not to remove too much of RSA keys ;-)

SSL VPN authentication using the ad group
Hi all
I tried to restrict users to authenticate to the SSL VPN using an ad server. I have install the AAA server with the IP address of the AD server and attributed to the connection profile as well; However, I see that any user who is a member of a group in AD is able to authenticate.
I want to only users who belong to the group "VPN users" get authenticated while everyone and all those who have credentials of the AD and not even a part of the 'VPN users' group is making authenticated.
Can someone advice how I can make the ASA authenticate users based on ad groups? I use the ASDM to configure my VPN RA.
Thanks in advance!
Kind regards
Riou
Hey riri,.
Try to use DAP to restrict access to users who belong to a specific ad group:
https://supportforums.Cisco.com/document/7691/ASA-8X-dynamic-access-poli...
Use the AAA attribute "LDAP .member of" to allow access to the users belonging to a specific group and deny access to other users.

For CISCO1841-SEC/K9, ssl and ipsec vpn connection vpn how, we can make and? The datasheet is not any specific number.
Thank you.
Dijoux
With the PIX and ASA, the number of peers is specified in the license and limited to the number specified in the license (so in support of peers, you must update the license). From my experience of the IOS application does not bind the number of peers for what anyone in the license. So, if you buy a feature set for IOS router supports IPSec/SSL VPN, then this is your license for IPSec and SSL peering (no separate license is required).

RVL200 firmware 1.1.12.1 - Windows 7 still does not work for SSL VPN
Try to connect RVL200 SSL VPN using Windows 7, IE 8.
After update to firmware 1.1.12.1, I am able to install the webcachecleaner, but when I tried to click on the padlock on the screen, I get
"Error: Virtual Passage not installed." Please install as Administrator".
I'm already the only administrator on the computer, and I installed the C++ 2005 Redistributable Package (x 64) according to the accompanying note. Date shows the add-on XTunnel IE 3 March 2010. The certificate is updated (expires 2011).
Any ideas how to get around this problem?
Thank you. Christina
On Windows 7 or Vista, Internet Explorer does not always run with administrator privileges. You must select the "Run As Administrator" option when you start the IEv8.

SSL VPN and RSA on demand tokens
Hello
I tried scouring the web and can't find anything on how to get this working. We have our SSL VPN using RSA atm but would also like to be able to use the version on request as well.
I was not able to find any doco on how to enable this.
Any help in pointing me in the right direction would be thank you much
Kris,
Any name of username/password authentication is (nearly) transparent to ASA.
ASA or any device authentication sends a request containing the credentials to the back-end server that meets the acceptance, rejection or in some cases, a challenge.
A notable exception side RSA's Adaptive Authentication (sometimes called tokenless) that requires further customization on the SAA.
The people on the side RSA are a smart bunch they can usually answer how their solution integrates with different vendors/solutions. If I am that prepare properly (that I could find with a quick query) there is no additional considerations side ASA save to set the right server and point it as the service of the methods (and if any NAT/ACL to allow users access to the server where you can request the token to send - usually in a zone demilitarized).
I am based on:
http://www.RSA.com/products/SecurID/datasheets/9240_SIDODA_DS_0310.PDF
and

Router WAN double with SSL VPN inaccessible for customers

The customer wishes to use the ADSL link to the normal navigation and external SSL VPN users to complete on the SDSL connection. I tried to configure the link failover for the ADSL SDSL.
What works:
-Access to the Internet for clients the
What does not work:
-The ADSL SDSL connection failover.

Hello
It works for me. When the client tries to resolve the fqdn for the domain specified in "svc split dns.." he will contact the DNS server assigned through the Tunnel. For all other questions, he contacts the DNS outside the Tunnel.
You can run a capture of packets on the physical interface on the Client to see the query DNS leaving?
Also in some routers, DNS is designated as the router itself (who is usually address 192.168.X.X), if you want to make sure that assigned DNS server doesn't not part of the Split Tunnel.

Hi all
I have a strange architecture including VPN and I have a few problems that I am not able to solve:
-J' use the ssl vpn gateway to allocate internal IP addresses of the local network described in the schema (8.8.2.0 or 8.8.3.0 according to the tunnel-group network.
-The purpose is for vpn clients directly access the internal network.
This works very well if there are strictly internal communications within the network. But recently, we have installed an application that needs to access both networks. No problem, I thought, but I was wrong, there seems to be a problem of routing inherent in the architecture in place.
Let me explain the problem:
-When I access the VPN, for example I will gave the 8.8.3.5 ip address.
-Im running the application that needs to open a page on the web server, located at 8.8.2.120
-l'asa receive my tcp syn datagram and forward it directly to the directly connected interface fa0/1 (based on the routing table)
-the web server returns the response, but he sends on its default gateway which is the cisco 6509.
-6509 it sends its vlan svi 2000
- and finally the ASA it receives on its interface fa0/2 but seems he falls as she opened a tcp on fa0/1 connection and receives the response on fa0/2.
I want it's traffic by tunnel to bypass the connected roads and transmit it to a default gateway of tunnel. This would ensure that the path for the request and the response would be the same.
I would like to know if there are orders of debugging for routing decisions validate my theory?
Do you know of any response to solve this problem?
Thanks a lot for your help.
When you configure the TCP State derivation always think ' which way is the SYN package coming?
Routing failed messages always have source and destination, are of course copied the entire message?
BTW, instead of letting clients SSL addresses attributed to vlan2000? Why not give them a separate subnet and the road back via correct interface?
I would also check your config and the routing :-) table

Routing IP will on SAA for SSL VPN
I have a question let internal DHCP network is 192.168.0.0 and if you configure SSL VPN on ASA to assign the ip address of 10.0.0.0 network routing where must be configured so that the customer can route between network?
2 lets say im using im 192.168.10.0/.20.0/.30.0 my network if I place ASA to assign 30.0 will be ther be conflict DHCP? or ASA DHCP will ONLY respond outside requests? (I mean Anyconnect)
Hello
You don't have to use a dynamic routing protocol if you need / want. In a simple network you could just use static routes.
That is the way that manage you routing I don't think it really changes the configuration at all.
This of course provided that the ASA is the default route outside of your network. Then all traffic to the networks VPN pool naturally would be always accessible from the local network as the default route would already be transfer all traffic to networks outside the local network to the ASA.
However if the ASA is not device gateway for all Internet traffic on your network then you will need to manage the routing so that the networks/subnets used as the VPN pools would be routed to the ASA on the local network.
