Basic querying AnyConnect VPN
I have two questions regarding Anyconnect VPN in ASDM.
VPN Wizard--> Anyconnect VPN Wizard--> VPN protocols
(a) SSL, anyconnect SSL will use and I only need to allows port 443 to the right of the ASA?
With SSL, can I use NFP function?
(b) IPSec, anyconnect using IPSec, and I need to allow IKE, ESP & AH.
Yes, what about your assumptions when you use another firewall. For SSL, it is just the TCP 443 port. For IPSec, you will need to allow ESP (IP Protocol ID 50), AH (IP Protocol ID 51) and ISAKMP (UDP 500 port). You also need the TCP 443 port to the first handshake with IPSec VPN and port UDP 4500 (IPSec NAT traversal).
SSL is the 'traditional' AnyConnect client access method and is also used for clientless SSL VPN (permit required). It is sometimes preferred for simplicity and knowledge.
IPSec is probably safer and recently available only with AnyConnect because it has a dependency on the use of IKEv2.
Or does the job.

Hi I'm new Anyconnect VPN. These are fundamental questions. The first step to set up the vpn is download image. What is this image? I noticed that the configuration of the VPN does not contain some general vpn configuration steps such as crypto isakmp policy and crypto ipsec etc. Maybe the image contains all of this information? If so, how to get the image? Thank you
IPsec is not a kind of SSL. It's a total different encryption mechanism.
IPsec uses pre-shared keys (almost always) and is so symmetric cryptography (the two peers have the same "secret"). Until there are 4-5 ears it was predominant VPN technology and is still widely used, particularly in site-to-site VPN connections.
SSL uses a PKI (PKI) with a private key ('secret') not shared between peers and therefore asymmetric. More new remote access VPN in recent years are based on SSL. SSL does not use lines of configuration of ipsec crypto or crypto isakmp but instead relies on certificates and trustpoints.
Complicating the landscape there is a new safer type of VPN IPsec is IKEv2. It is not widely adopted in my experience, but is increasingly used by organizations and agencies who need to comply to strict government standards.

Hello friends!
I ve been trying to configure the anyconnect VPN, but I cannot generate the CA, probably I m doing wrong sothing.
To be honest, I Don t know if the problem int this VPN is only what is missing, but is the only thing that I've seen what can be a problem.
Someone knows how to generate the CA in the ASA?
Hi Marcio,
Please follow this link:
https://supportforums.Cisco.com/document/12597006/how-configure-ASA-CA-s...
Do you want authentication certificate based for Anyconnect users?
I'm not sure we really need a CA in this case.
You can try to check this third party link to configure the Anyconnect on SAA basic settings:

Hi all
There is a single query on the anyconnect ASA 5510 deployment. We have the ASA 5510 with security more lic. and for lack of run (client) anyconnect VPN for concurrent users. It requires a separate licence for Anyconnect (client).
5510 a security more lic.
Firewall settings:
AnyConnect Essentials: disabled
AnyConnect Premium: 2
Max VPN session: 250
If I run anyconnect VPN it takes max 2 session. But need more sessions.
Thank you
Vishaw
If you just want to use computers to connect to anyconnect using the AnyConnect client and not the clientless SSL, you only need to purchase the license AnyConnect Essentials for the amount of connection you need (supports up to 250). If you need SSL clientless also, then you must purchase the Premium license. If you also require that mobile phones, tabs, etc. need to connect to the AnyConnect client, then you need client AnyConnect mobility.
The following link gives you an overview of the licnenses for the 5510 and other models ASA.
In addition, here Pete does a good job of explaining AnyConnect licenses.

ASA Anyconnect VPN do not work or download the VPN client
I have a Cisco ASA 5505 that I try to configure anyconnect VPN and thought, I've changed my setup several times but trying to access my static public IP address of the external IP address to download the image, I am not able to. Also when I do a package tracer I see he has been ignored through the acl when the packets from side to the ASA via port 443, it drops because of the ACL. My DMZ so will he look like something trying to access the ASA via the VPN's going to port 443. Here is my config

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:

Hello
You could start by adding the following configurations
permit same-security-traffic intra-interface
This will allow traffic to the VPN users access the interface ' outside ' of the SAA and to leave to the Internet using the same interface ' outside '. Without the above command, it is not possible.
Also, you need to add a NAT configuration for VPN Client users can use the Internet connection of the ASA
To do this, you can add this command
NAT (outside) 1 172.16.0.0 255.255.0.0
This will allow the PAT for the Pool of VPN dynamics.
Hope this helps

ASA 5510 Anyconnect licenses with Cisco Anyconnect VPN IP phone
Hi, hoping someone can shed some light on what I'm just more confused over trying to get by. Not sure if this goes in the section IP Telehpony or here...
We have an ASA 5510 with the base license. We need to install IP phones to home teleworkers, and I understand there are Cisco IP phones that have built-in VPN clients to enable a tunnel to the central private network. IT seems that you can't use Anyconnect VPN to do this, and I am trying to establish what upgrade licenses, we must apply to the ASA, as both Anyconnect licenses that you get for free on the SAA is not enough.
This is the phone that we seek;
I want to know is the Anyconnect Essentials license will work with these IP phones?
When I do a version of the show,
The devices allowed for this platform:
The maximum physical Interfaces: unlimited
VLAN maximum: 50
Internal hosts: unlimited
Failover: disabled
VPN - A: enabled
VPN-3DES-AES: enabled
Security contexts: 0
GTP/GPRS: disabled
SSL VPN peers: 2
The VPN peers total: 250
Sharing license: disabled
AnyConnect for Mobile: disabled
AnyConnect for Linksys phone: disabled
AnyConnect Essentials: disabled
Assessment of Advanced endpoint: disabled
Proxy sessions for the UC phone: 2
Total number of Sessions of Proxy UC: 2
Botnet traffic filter: disabled
This platform includes a basic license.
It shows "AnyConnect for Linksys phone: Disabled", it is the same for the Cisco IP phones? It is the kind of specific license, should I seek for Anyconnect on IP phones or will Essentials?
Hi Leo,
you will need 2 licenses: an Anyconnect Premium license and a permit «Anyconnect of Cisco VPN phone»
ASA 8.2 and earlier license "for Cisco VPN Phone" has been named "for phone Linksys' it's the same.

Access via L2L AnyConnect VPN IPSec
I'm trying to connect two ASA 5505s for a IPSec L2L VPN. They can connect, but not pass traffic from the AnyConnect subnet. I've added the config from ASA-2, with the LAN subnet of 192.168.138.0 and a subnet of 192.168.238.0 for AnyConnect client. I'm trying to get the AnyConnect Clients access to the 192.168.137.0 LAN behind ASA-1 at 1.1.1.1. Having both 192.168.238.0 and 192.168.138.0 both access 192.168.137.0 is acceptable. There's probably a lot of cruft in this config, as I've been reading all over forums and docs without much success. Can someone point me in the right direction? : ASA Version 8.2(1) ! hostname asa-wal names name 192.168.238.0 anyconnect-vpn ! interface Vlan1 nameif inside security-level 100 ip address 192.168.138.1 255.255.255.0 !

Post edited by: Shawn Barrick - line breaks
It seems good Shawn but I just noticed an error on the asa-wal, you have a vpn-filter applied on the DfltGrpPolicy and since you have not any value defined the strategy of Wal-AnyConnect group then will inherit the DfltGrpPolicy vpn-filter, don't forget that the vpn filters should be applied to the incoming direction, I mean pool resources you want them to have access to. It's the ACL you have for the filter:
NO_NAT list extended access allowed anyconnect vpn - ip 255.255.255.0 everything
This isn't in the inbound direction, increasingly looks like you want to allow access to what it is as long as the traffic is coming from the 192.168.238.0, if that's the case, you can do this:
attributes of Group Policy DfltGrpPolicy
VPN-filter no
Do not forget to disconnect and reconnect after the above change...
If you really need to be more specific, allowing traffic for clients then apply the inbound rules, for example:
Your pool is here 192.168.238.0/24 and the local subnet is 192.168.138, to this effect, the 192.168.137 is considered to be local too because of the perspective Anyconnect we'll see in the room even if it is a remote network accessible via a L2L tunnel of the Anyconnect client does not.
The following AS will allow the Anyconnect Telnet client for local networks:
permit access-list vpnfilt-ra 192.168.238.0 255.255.255.255 192.168.138.0 255.255.255.0 eq 23
permit access-list vpnfilt-ra 192.168.238.0 255.255.255.255 192.168.137.0 255.255.255.0 eq 23
The following ACE will allow local networks of Telnet for the Anyconnect Client:
permit access-list vpnfilt-ra 192.168.238.0 255.255.255.255 eq 23 192.168.138.0 255.255.255.0
permit access-list vpnfilt-ra 192.168.238.0 255.255.255.255 eq 23 192.168.137.0 255.255.255.0
Note that the two first ACE will allow LAN launch connection to the Anyconnect client on any TCP port if he uses a source 23 port while the last two ACEs allow the Anyconnect client connect to networks the on any TCP port if he uses a port source from 23.
Kind regards

AnyConnect VPN and HP Office Jet Pro 8500 A910
I can print from my laptop IBM T400 running Windows 7 64 bit. However, when I log in work AnyConnect VPN, I can't print. He says that the printer is disconnected from the network, even if it is connected. IT support at work said he can't change or adjust the VPN settings. The only way I can print is to disconnect from the VPN. Is this what I can adjust on the software of the printer or the printer itself?
Hello
To be able to print on the local network when you are connected to a network remote VPN might be possible by changing the VPN split tunneling configuration.
However, it is depands on the VPN features and cannot be authorized because of the security requirements of your IT Department.
Anyway, there is no way to configure such a thing by the printer or the printer software... It is directly affected by the configuration of the network and therefore require to modify VPN settings.
Kind regards

Cisco AnyConnect VPN Client maintains reconnection
Hello
We have recently installed an ASA5505 and activated the VPN access.
Two of my colleagues have no problems connecting to the VPN using Cisco AnyConnect VPN Client, but I do.
I am still disconnected after a few seconds with the message:
"A VPN reconnect gave rise to different configuration settings. VPN network interface is to be reset. Applications using the private network may be required to restart. »
Cisco AnyConnect VPN Client Version 2.5.2019
I work with Windows 7 but the same thing happens when I try to connect using my computer that is running Windows Vista.
My colleagues also using Win7
I also tried to disable the Windows Firewall.
Any help would be appreciated.

IOS anyconnect vpn group lock and user restrictions
Dear Experts,
I now have two questions about cisco IOS vpn on ISR G2:
1 is it possible to lock user group in IOS anyconnect VPN we can do in ASA? If so, can someone share the steps for her?
2 - a customer wishes to restrict the anyconnect user login as it might turn the connection to the user on request. That is to say whenever the user wants to connect via vpn to ask the administrator to allow connection. can we do without deleting the username and create again?
the other may be on ASA or IOS.
Please see this guide:
http://www.Cisco.com/c/en/us/support/docs/security/iOS-easy-VPN/117634-c...
As he points out, "for the Cisco IOS group-lock and the ipsec: use vpn-group, it only works for IPSec (the easy VPN server)." In order to group-lock specific users in specific contexts of WebVPN (and strategies Group attached), authentication domains should be used. »
If you lock a user to a policy that authenticates, but does provide real access permissions (say an ACL that blocks all traffic to the private network) then you have essentially made their ability to non-functional connection.
If you use an external AAA server (for example, RADIUS or LDAP), then you can move in and out of the group which is authorized without disable VPN access / delete their account altogether.

CISCO ANYCONNECT VPN CISCO VPN CLIENT
Hi, I was in the process of configuring cisco anyconnect vpn for ip phones to our local obtained the license for them either, the question that I get is that I already have remote configured cisco connect via the old cisco vpn client.
now, if I activate the anyconnect ssl on the same outside the interface both can exist without conflict or maybe I need to migrate users to install the end customer for anyconnect system software to connect.
I also need help with authentication of certification.
concerning
You can run both VPN at the same time without problems.
However, you should try and migrate everyone to the latest technology Anyconnect SSL anyway.

Hello
I have configured AnyConnect VPN with split tunneling, so my internal networks is in the tunnel and get internet directly (not via an internal network).
But we want to access one of the public IP (8.8.8.8) through AnyConnect VPN tunnel.
When we check the capture of packets on an external interface, trying to ping 8.8.8.8 showing the icmp-request package but not get icmp-response packages.
Additional configuration required to access the ip address above by tunnel?
We have activated the below configuration as well.
