ASA checks AnyConnect VPN computer name
Hi all
I have searched the Forum and documentation, but have not found a solution to my problem. I'm guessing it happens sometimes, but maybe I'm looking for the wrong thing. We AnyConnect deployed across our cell phones, but have trouble with employees who do get the software from other sources AnyConnect and install on personal computers. We are an agency, although relatively small, but we have policies in place and I need to lock for users unable to connect to the VPN unless you're a book PC connected to our AD domain. I found a possible solution is to use dynamic access within the ASA policies to check the Windows computer name. So I set up LDAP and has created a policy to check an AAA attribute. It lets me select "MemberOf", which I assume it is the Group of users, but I need to check the name of the computer on the client before allowing access.
Step by step of what I did, does anyone know of a more logical or easier way to lock on what AnyConnect VPN client computers can be used?
Or if I go about this common sense with dynamic access policies, anyone have any suggestions or knowledge of documentation that helps to configure things properly when you check the computer name LDAP attribute?
Thank you!
JD
Hey Joe,
You do not need LDAP to do this, what you need is CSD (Cisco Secure Desktop) combined with DAP.
Once you enable SSC, edit your DAP strategy and instead of an IPN to attribute you to try, add an attribute of endpoint (on the right hand side).
To verify the host name, select the type of the attribute "peripheral".
Alternatively, you can also activate the sweep of host (under Contract) and let the CSD to check the presence of a file with a certain file name, or a registry entry or a process name. CSD passes the result of this verification to the PAD, so you can use it in a policy (attributes of endpoint of type process, registry and files).
Another alternative is to use the CSD with a policy before opening session - that you cannot check the host name, but it does not have control over the IP, OS type, certificate as well as the presence of a process, the registry key, the file. In this case you need not to DAP.

MAC and PC can reach the same an ASA for Anyconnect VPN?
Hi, we have MAC and PC users. We configure the Anyconnect VPN in an ASA. But two users need two image of sorts. We must therefore use the two commands:
AnyConnect image disk0: / anyconnect -win- 3.1.04066 - k9.pkg
AnyConnect image disk0: / anyconnect -macosx- i386 - 2.5.2014 - k9.pkg.
This is what two commands cannot coexist in an ASA. How to solve the problem? I hope your suggestion. Thank you
They can co-exist, but you must add different sequence numbers at the end of each command.

Cisco ASA and AnyConnect VPN certificate error
Hello
I am trying to configure Cisco AnyConnect VPN and everything works, but I get this warning message when the connection is opened:
I don't have public certificate in ASA. Is it possible to use the self-signed certificate and get rid of this warning message?
Hello
This is expected behavior on the SAA for an SSL connection. You can certainly use the certificate self-signed on the SAA and then apply it on the external interface.
Once done, you will need to install this certificate on the clients and this will alleviate the popup error message.Here is a document that you can refer to create a self-signed certificate.

Select the timeout on ASA Cisco Anyconnect VPN
Hello world
I use the Cisco Anyconnect VPN client with the ASA 5540 firewall. I need allow a time-out on the VPN clients, so they log off after x hours of inactivity.
Thank you to
Best respect
Hello
To my understanding of the default timeout value is 30 minutes
You should be able to change this setting in the "username" configurations (if you use LOCAL AAA on the SAA) or under the configurations of the 'group policy' .
The command is
VPN-idle-timeout

ASA 5512 Anyconnect VPN cannot connect inside the network 9.1 x
Hello
I'm new to ASA, can I please help with this. I managed to connect to the vpn through the mobility cisco anyconnect client, but I am unable to connect to the Internet. the allocated ip address was 172.16.1.60 and it seems OK, I thought my acl and nat is configured to allow and translate the given vpn ip pool but I'm not able to ping anything on the inside.
If anyone can share some light... There's got to be something escapes me...

inspect the icmp errorYour NAT0 configurations for traffic between LAN and VPN users seem to. Your Split Tunnel ACL seems fine too because it has included 192.168.0.0/16. I don't know what are the other.
I wonder if this is a test installation since you don't seem to have a dynamic PAT configured for your local network at all. Just a few static PAT and the NAT0 for VPN configurations. If it is a test configuration yet then confirmed that the device behind the ASA in the internal network has a default route pointing to the ASAs interface and if so is it properly configured?
Can you same ICMP the directly behind the ASA which is the gateway to LANs?
If you want to try ICMP interface internal to the VPN ASA then you can add this command and then try ICMP to the internal interface of the ASA
Int Management-access
As the post is a little confusing in the sense that the subject talk on the traffic doesn't work not internal to the network, while the message mentions the traffic to the Internet? I guess you meant only traffic to the local network because you use Split Tunnel VPN, which means that Internet traffic should use the VPN local Internet users while traffic to the networks specified in the ACL Tunnel Split list should be sent to the VPN.

Anyconnect VPN management if password password has already expired
Hello
I have ASA Cisco AnyConnect vpn with Microsoft AD ldaps authentication. In the Group of the tunnel, I configured management password (password expire days 14). It works but my testing it seems to be no possible to update the password if it is already expired. No way to solve this problem?
Thank you
Hi, Giuseppe.
Yes, the change of password should work even when he arrived at expiration.
Maybe you can try placing screenshots on the user and the server and make sure that the TCP process is successful when the password has expired.

Hi, we have MAC and PC users. Two users could reach inside the network through ASA and Anyconnect VPN. However, MAC users can not have connection (please see screenshot in attachment). The output of the show run webvpn command is below:

We don't think that this is the reason why MAC users are unable to reach the inside of the network because we do not have this command for a long time. Any suggestions can give? Thank you.
> The question is that the command for MAC was not there for long. Why is it could work when the order wasn't there?
I don't know, but I remember that in versions, it was not necessary to have * all * images in flash. Perhaps this changed some time. , You upgrade your ASA recently before the problems began?

IP Phone/Android IPSEC VPN to ASA using AnyConnect
With course of Blackberry support in our Organization, we are eager to implement, configure, and deploy a vpn to access remote ipsec Ikev2 of our ASA 5540 9.1 (5) 19 (license Premium VPN) for the iphone and android.
Was so fair to ask is - it possible, if it is possible, what is the best approach to take, and if someone has a recommended best practices?
And do we need to purchase several licenses for AnyConnect for Mobile?
As looked at loads of documentation, but have I just more confused.
So, any help much appreciated.
Thank you
NESSIE
Hi Nessie,

We have a pair of cisco ASA 5520 with version 8.2 (5) works well with active mode / standby. As the situation requires, we intend to change the SSL vpn to clientless SSL VPN (AnyConnect Premium) to anyconnect vpn with mobile clients (IOS & Android)
Please specify below
(1) I have read, we cannot have two Anyconnect Essentials & AnyConnect Premium on the same system time. We need to disable accordingly to our need-pl correct me?
(2) what is the best way to have the device for end-user client deployment? pushing of ASA or install individually on the system? Can I have the best, I mean the latest version of windows, client MAC e.t.c I shud get?
While pushing ASA LU that much memory cache will be used, since we have IPS (AIP - SSM) modules has also installed on ASA who shud method I adopt here?
(3) what is the exact product for license Anyconnect Essentials & customer name mobile (IOS & Android) we get from cisco?
(4) once I get the correct license how do I active in systems? should I remove the failover command and install the license in two devices separately?
(5) Finally, I need to authenticate vpn anyconnect essentials with LDAP that is already configured for clientless SSL VPN(AnyConnect Premium). any suggestions here?
Below the version Sh emitted by the devices, it seems essential Anyconnect is already active... Please correct me?

Thank you
1 correct. You can run one or the other, but not both.
2 since you have the upgrade memory to 2 GB, you should be fine perform web deployment via the pkg file method.
3. for a 5520, you need:
L-ASA-AC-E-5520 =
L-ASA-AC-M-5520.. .to the Essentials and Mobile licenses respectively.
4. on ASA 8.2, you need licenses for both units. If you upgrade to 8.3 + (8.4 (7) recommend at least), you can share licenses between members of a pair of HA. If you choose not to upgrade, just apply the key of activation on the rescue unit, then on the unit activates. You don't need to move on and in the failover configuration. Failover of the rescue unit status will show as ineligible briefly while he holds the new license is not the case of the active unit. Which will be resolved after you have applied the same license on the main unit. (If you were on 8.3 + would not happen at all).
5. simply create a new connection profile for customers of Essentials by using the same AAA server group.

Hi team
Hope you do well. !!!
currently I am doing a project which consists in CISCO ASA-5545-X, RADIUS (domain controller) server for authentication. Here, I need to configure Anyconnect VPN and host checker in cisco asa.
1 users will connect: user advanced browser on SSL VPN pop past username and password.
2. (cisco ASA) authentication: VPN sends credentials to the RADIUS server.
3 RADIUS server: authentication: receipt and SSL VPN (ASA) group.
4 connectivity creation: If employee: PC so NAW verified compliance, no PC check Assign user to the appropriate role and give IP.
This is my requirement, so someone please guide me how to set up step by step.
1. how to set up the Radius Server?
2. how to configure CISCO ASA?
Thanks in advance.
Hey Chick,
Please consult the following page of installation as well as ASA Radius server. The ASA end there is frankly nothing much difference by doing this.

BTW, I changed the NAT configuration many attempts the problem, this is the current...
YPU need to allow your client VPN address pool (10.6.4.1 mask - 10.6.7.254 255.255.252.0) ssh and http from 'outside' access, which is where they come from. Add them to the:
http 0.0.0.0 0.0.0.0 inside

SSH 0.0.0.0 0.0.0.0 inside

SSL VPN and access to computers by computer name
I have a SonicWall TZ 205 running SonicOS Enhanced 5.9.1.0 firmware - 22o. It seems that I have things to work except solve computers by computer name. Since the client SSL VPN Extender I can ping machines, I can reach their actions through \\192.168.1.12\myshare for example but not of \\mycomputername\myshare. I tried enabling NetBIOS settings but still does not. Thoughts please.
Thank you
OK so in this case you can resolve names of machine by completing the "Wins servers" section in the same pop-up down (if you have a wins server).
Often the DNS servers are also the wins servers.
If you don't have a wins server, then will not work without creating files on each machine that needs to resolve the name of the host computer.
Technical Net Bios is not a routable protocol
