ACL and anyconnect ssl vpn
Hello world
I was testing the few things at my lab at home.
PC - running ssl vpn - sw - router - ISP - ASA (anyconnect ssl)
AnyConnect ssl works very well and I am also able to access the internet.
I use full tunnel
I have ACLs on the external interface of the ASA
1 | True | any | any | intellectual property | Deny | 0 | By default | [] |
I know that the ACL is used to traffic passing by ASA.
I need to understand the flow of traffic for internet via ssl vpn access. ?
Concerning
MAhesh
As you correctly say, the ACL interface is not important for that because the VPN traffic is not inspected by the ACL. Of the at least not by default.
You can control the traffic with a different ACL that is applied to the group policy with the command "vpn-filter". And of course you need a NAT rule that translates your traffic when running to the internet. This rule should work on the pair of interface (outside, outside).

Cisco ASA AnyConnect SSL VPN - certificates + token?
Hello
I'm looking for an answer is it possible such configuration:
The Cisco AnyConnect SSL VPN service with two-factor - first method is the Microsoft CA certificate local and second method - a token solution Symantec VIP password?
I don't know if two-factor authentication is user/password from Active Directory + OTP by Symantec VIP there is no problem, because you can send the user + pass with Radius, but with certificates I do not really understand who will check the validity of the certificate, which certificate, we will send you to the RADIUS for the validation server and how the configuration of the point of view of ASA will look like.
Thank you very much for the help!
Hi Alex,
I don't see a problem with having certificate + token to connect to the VPN. Certificate authentication must be performed on the SAA, see an example below:
https://supportforums.Cisco.com/blog/152941/AnyConnect-certificate-based-authentication
Authentication token can be specified as primary/secondary (authentication SDI) on the SAA, an example below:

Hi guys,.
I am currently ut setting for the first time on a Cisco ASA 5505 Cisco AnyConnect SSL VPN.
I enclose my topology.
I ran the wizard of the ASDM on the ASA2 I want to use for my VPN connections.
Everything works fine except that I can't access any internal computer servers on my network.
I do a specific configuration because my servers have a different default gateway of the ASA that I use for my VPN?
I have since the ASA2 the 192.168.10.0 network.
my remote ip address of the pool is 10.0.0.1-10.0.0.10/24
config (I've included what, in my view, is necessary, please let me know if you need to see more):

Hello
The unit behind your ASAs on the internal LAN should really be a router switch or L3 and not a basic L2 switch.
You now have an asymmetric routing on your network, and this is the reason why the connection of the VPN device will not work.
The problem comes from the fact that internal devices use the ASA1 for the default gateway. When trying to connect to the VPN Client, the following happens
- Client VPN armed sends TCP SYN that happens by the VPN with the ASA2
- ASA2 passes the TCP SYN to the server
- Server responds with TCP SYN ACK for the VPN Client and sends this information to the ASA1 as the destination host is in another network (vpn pool)
- ASA1 sees the TCP SYN ACK, but never saw the TCP SYN so he abandoned the connection.
To work around the problem, you need to essentially configure TCP State Bypass on the ASA1 although I wouldn't really say that, but rather to change the configuration of the network so that traffic makes this way to start.
An option, even if not the best, would be to set the LAN of the ASA2 to ASA1 on some physical ports and set up a new network connection between them (not the same 192.168.10.x/yy). In this way the ASA1 would see the entire conversation between servers and VPN Clients and there are no problems with the flow of traffic.
But as I said it probably still isn't the best solution, but in my opinion better than having recourse to special configurations ASA1.
There could be a 'special' configuration on the ASA2 that you could use to make the Client VPN connections operate in their current configuration, without changing anything in the physical topology.
You can change the NAT for VPN Clients configuration so that the VPN ALL users would actually PATed to 192.168.10.4 IP address when they connect to your internal network. Given that the server would see the connection coming from the same network segment, they would know to forward traffic back with the ASA2 rather than ASA1 like her today.
If this is not an ideal solution.
No source (indoor, outdoor) nat static any any static destination NETWORK_OBJ_10.0.0.0 NETWORK_OBJ_10.0.0.0 non-proxy-arp-search to itinerary

Essential AnyConnect SSL VPN?
Hello
I'm a bit confused. What is the difference between licenses(L-ASA-SSL-PR-25=) SSL VPN and Anyconnect Essential(L-ASA-AC-E-5510=)? I'm trying to be more objective and confused about what to buy.
1 allow users to VPN through SSL and telnet on the unix system.
2. allow users to use RDP sessions, once connected to the windows system.
3 allow users to leave their outlook to connect to the Exchange once connected server.
I need a solution that would download the client (just the browser to https://x.x.x.x) and let the customer gets pushed. I also need another VPN profile that uninstalls all customer downloaded when you are offline. The second profile is for people who are using public PC of the trip.
Also, do I need license Anyconnect Mobile wanted to use iPhone or iPad to access vpn SSL url?
Any response would be greatly appreciated.
Thank you
Sam
Clientless SSL means you are tunneling SSL to the ASA without (AnyConnect) client.
In other words, the remote computer needs only a browser to establish the secure HTTPS connection and access a potal web that may redirect access to internal resources. This type of connection (without customer) allows access to web applications and via port-forwarding to enable access to other TCP applications.
When you need full network access (imitating the IPsec VPN client) you need the connection SSL (AnyConnect) Client-centred.
This does not require a Web portal, provides with a complete full network access.
If you use AnyConnect, the client can be pushed from the ASA to the customer via the HTTPS connection (and kept on the remote system or removed) depending on the configuration.
If you are looking for a remote SSL connection that can access a portal and newspaper via telnet/RDP, you can use clientless SSL with port forwarding.
If you want to that remote clients have full network access (everything as if they are sitting in the local network), will need you the AnyConnect.

AnyConnect SSL VPN Split tunneling problem
Hello
We have home users that VPN in on a regular basis, but when they VPN in they cannot print locally or to connect to local resources. Is there a way to activate the split for all remote users VPN tunneling? It is not possible to add all the remote subnets, especially since I don't know which subnets are used and it would be a question of management. I noticed that when I connect to the House a new route is added to my PC, who prefers the VPN link.
I noticed one of the options with the client Anyconnect is 'enable local LAN access (if configured) '. Can I use?
Thanks in advance.
Hello
According to my understanding, you need to connect to your local printers while you are connected to the ASA via SSL VPN.
You can do this by creating a policy of exclusion of tunnel split on SAA and the local lan access on the client option, or you can use the profile AnyConnect allowing local lan access.
Please find the link below: -.
I hope it helps.
Thank you

Cisco ACS 5.1 and ASA SSL VPN change or notify the expired password
Hello
Now, my ACS and ASA related to RADIUS (MSCHAPv2). I've set up password life on GBA and password management on SAA. But Cisco ASA did prompt change or whatever it is to notify when the user tries to log on with Clientless SSL VPN. Could you advice me everything to change, or notify the expired password?
PS.
I check change password on the first login of th on ACS this confirmation of the ASA to change password dialog box. But I want change or warn when the expired password
Thank you
The default password is marked as disabled after expiry
I think that there is an improvement for this in the 5.2.0.26.2 patch and above, which includes the following:
CSCtk32168: Add an option to change the password when the password expires (T + and Radius)
After you install this hotfix, you get an option to the user authentication settings is:
-Disable the user account
-Expire the password
When the expiration period is exceeded
If password is expired then user will be asked to change password next authentication
Note this latest patch for 5.2 is 5.2.0.26.4. All patches are cumulative

AnyConnect SSL VPN through IPSEC Tunnel
Everyone was able to set up and connect using Cisco anyconnect vpn ssl on a Cisco IPSEC's tunnel. I used this in the past from a Windows XP system in the past but its not working now. None of my users are able to cooect using the Anyconnect on IPSEC. IPSEC on its own works very well.
The Anyconnect is also able to create the connection to its ASA firewall however its not able to route all traffic through. Do you have any suggestions?
Thanks for the update.

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 ;-)

IPHONE 4.0 with Anyconnect ssl vpn client
Hello
It does anyone know how to configure an Iphone 4.0 with client anyconnect with certificate-based authentication?
I just found that is supported, but I have not found any documentation about it.
Hello
The client anyconnect for iPhone has not yet been published, and so now you can configure.
Kind regards

Cisco Anyconnect VPN vs IPSec AnyConnect SSL
Hello
Can someone tell me what is the difference between the Anyconnect SSL VPN and Anyconnect VPN IPSec.
When we use one and not the other?
Thank you very much.
Best regards.
Hello Abdollah,
AnyConnect based on the SSL protocol is called Anyconnect SSL VPN and if you deploy Anyconnect with the IPSec protocol, it is called IKev2.
AnyConnect (via IKEv2 or SSLVPN) does not use a pre shared key to authenticate the user. A certificate will be used to authenticate the user and the ASA of + pass and the certificate used to authenticate the user. The XML profile is necessary just to use the Anyconnect IKEv2 client rather than the default of SSL when connecting to the ASA.
Here is the doc announced some of the benefits of using Anyconnect with Ikev2 rather than SSL VPN.
http://www.Cisco.com/en/us/docs/iOS-XML/iOS/sec_conn_ike2vpn/configuration/15-2mt/sec-cfg-IKEv2-Flex.html#GUID-6548042E-1E4C-416A-8347-00DCF96F04DFIn essence, if you have a simple deployment, then you can go with the installation of SSL VPN and if you want to take advantage of additional features, you can use Anyconnect with IPSec.
Kind regards

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.

Router WAN double with SSL VPN inaccessible for customers
I have a configured in a Dual WAN setup Cisco 888. There is an ADSL link connected to the VLAN 100 and a SDSL link associated with the Dialer0. 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.
-Access SSL VPN for customers. Surf to the external IP address will cause only a page by default HTTP. Specification webvpn.html results in a 404 not found error.

Any suggestions on where to look?
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.

ASA 5505 SSL VPN license update
Hi all.
Our ASA 5505 with DATABASE default license allowing only 10 simultaneous vpn sessions (including 2 Anyconnect + IPsec). attached a TXT file with the license information. This Firewall is's use only for vpn access, and we less vpn tunnel vpn IPSec-L2L, anyconnect client SSL and IPSec client access configurations vpn to the top and race walk,.
We are in terms of upgrading vpn license to archive IPSec 10 and 10 Anyconnect and 1 anyconect mobile VPN sessions in time. so my questions are;
1. can I buy "ASA5500-SSL-10 =" accounting and to upgrade our ASA 5505 without having to buy "L-ASA5505-SEC-PL =" license of pus of security.
2. asa use to upgrade only Anyconnect SSL vpn license while keeping 10 vpn IPSec comes with the base license.
Thank you & you expects value comment
Thank you
JCK
1. Yes.
2.Yes.
If you want to keep Clientless SSL VPN you do not want to continue with the addition of the ASA5500-SSL-10 = part. If you can do without client (including the conversion the two existing ones), more economically, you can opt for Security Plus and AnyConnect Essentials licenses. (US$ 800 vs price $1250).
In both cases, the Mobile requires the AnyConnect Mobile (ASA-AC-M-5505) license.
