Restriction of VPN AnyConnect Source (Caller-ID)
Hi all
I was wondering if it is possible on the Association or ASA to restrict access to a political group according to IP address, they come? For example, if I wanted to home users to connect to the external interface of the firewall to authenticate with a token, but if they are in the Office to connect to the internal interface and just use LDAP. The two work these options but this does not prevent someone from home to authenticate off the coast of LDAP of the House. I know that Ray has the Caller-ID field that has the IP address of the authentication device. I was wondering if it is possible to use this information on the ASA or ACS to add the control, I need. Any ideas?
Kind regards
Mike
Hi Michael,
you have several options:
-l'ASA indeed sends 2 attributes to a Radius server that contains the ip address of the client. It's 'debug RADIUS' when I connect from a client with the ip 192.168.0.98:
RADIUS: Type = 31 (0x1F) Calling-Station-Id
RADIUS: Length = 14 (0x0E)
RADIUS: Value (String) =
31 39 32 2e 31 36 38 30 2 2 39 38 | 192.168.0.98
...
RADIUS: Type = 66 Tunnel-Client-Endpoint (0x42)
RADIUS: Length = 14 (0x0E)
RADIUS: Value (String) =
31 39 32 2e 31 36 38 30 2 2 39 38 | 192.168.0.98
Now if you configure ACS to generate a different response based on the value of Calling-Station-Id or Tunnel-Client-Endpoint, I don't know (I mean I'm sure you can, but it's been a while since I have anything fancy on ACS) you can ask this question in the forum of AAA.
-If you want ASA to make the decision, you can do this with CSD (Cisco Secure Desktop - requires a license). CSD to create policies based on the features of endpoint (client) as the version of the antivirus installed, but also the ip address of the client. You may need to use in combination with DAP (dynamic access policy) to allow/deny access to a certain group, based on criteria of CSD endpoint.
- but for the scenario specific you describe, you might be able to solve this problem by simply specifying interface in the Group of authentication servers.
That is, if you currently have
attributes global-tunnel-group-of-inside
authentication-server-group MyLDAP
can change this:
attributes global-tunnel-group-of-inside
authentication-server-group (inside) MyLDAP
This will cause LDAP to be used only for connections from the inside. Other connections will use the LOCAL (so anyone with an account on the SAA will be always able to connect outside this group - in order to avoid that you can create a new aaa server group with a non-existent server and use it for external authentication).
Or maybe merge with your existing 2 groups into a single,
tunnel-group of no matter where-global attributes
authentication-server-group (inside) MyLDAP
authentication-server-group (outside MyTokenServer)

Cisco ASA 5510 - restrictions of VPN (AnyConnect) based on the AD user or IP address
Hello
I want to test how to restrict access user on an ASA 5510 AnyConnect. In politics, I can define what networks will go through the VPN tunnel and which not (split tunneling). The ASA has a LDAP connection and only AD users with a special security group can connect over AnyConnect.
On the other hand I would like to restrict access for special users within a VPN policy.So my question:
What are your recommendations to implement this szenario?My two ideas would be:
1. the access rules based on the user of the AD.
2. special reserve IP addresses in the pool of addresses AnyConnect for some users, so I can limit access to the normal firewall rules base based on the source IP address.What are your recommendations and is it possible to realize my ideas (and how)?
Thanks in advance
Best regards
Hello
I will suggest that you configure a second ad group in the server and another group strategy in the ASA, you can configure certain access on each group policy "the installer of the filters, assign different split political tunnel, different ACL' and in the ad server, you can assign users for example to the AD Group A and AD Group B based on the access you want to give them now , you must configure LDAP mapping to assign the user specific group policy that you want based on the AD group that they belong.
You can follow this documentation that will help you configure the LDAP Mapping:

Hide the AnyConnect VPN AnyConnect GUI Module
Dear team
We are wired deployment 802. 1 x with Posture and that NAM is sufficient for us.
but when installing AnyConnect vpn module must be installed and cannot be avoided, so VPN tab is also visible in the GUI AnyConnect interface,
I need to disable the VPN tab from the interface chart anyconnect, because it is not used and confusing for end users.
We have anyconnect-win-4.1.00028-pre-deploy-k9.
We have a manual installation of AnyConnect on PC or Client Provisioning, we don't use MSI
Please suggest 'VPN profile' to end users, which will hide this vpn module.
Thank you
Ahad
Your situation is highlighted in the AnyConnect Administrator's Guide as well:
When you configure the object Configuration AnyConnect to ISE, unchecking the VPN module under the AnyConnect Module selection does not disable VPN on the customer deployed/put in service. You must set VPNDisable_ServiceProfile.xml to disable the VPN AnyConnect GUI tile. VPNDisable_ServiceProfile.xml is on EAC with other files AnyConnect.
The xml file, you need should be on the AnyConnect downloads page, but is not. There's a BugID noting that (CSCus26084). Work around the BugID does not work for me, but it could for you.
The profile CAN be found in the msi file - if you open with 7-zip, you can find the file. She is short, so I'll just paste here:

Hi all
I'm trying to assign the attribute DAP users VPN (Anyconnect 3.0 +) who fulfil certain conditions of registry. When setting up political DAP, while selecting the condition of the register, it is in error as "secure desktop cisco (CSD) is not enabled, CSD should be enabled to configure the registry endpoint attribute. But as I link percevied, to check the attribute registry "scan host' which is integrated in the module anyconnect 3.0 will be charged. So why he asks me to activate the CSD? CSD is really necessary to verify the registry attribute even if we use anyconenct 3.0 +? Any pointer
The end of the ASA must be activated and more bits based on AnyConnect.
Notes elsewhere in the link you quoted, it is said ' host Scan automatically identifies the operating systems and service packs on any remote device establishing a clientless SSL VPN and AnyConnect Cisco client session and when the host Scan/CSD or CSD is activated on the SAA. " (emphasis added).
FYI Cisco is to denigrate these features over time for the Posture of scanning at the ISE in conjunction with the new posture AnyConnect 4.0 module.

WebVPN and remote vpn, ssl vpn anyconnect
Hi all
Differences between webvpn and remote vpn, ssl vpn anyconnect
All require a separate license?Thank you
Hello
The difference between the webvpn and SSL VPN Client is the WebVPN to use SSL/TLS and port
send through a java application to support the application, it also only supports TCP for unicast traffic, no ip address
address is assigned to the customer, and the navigation on the web in the tunnel is made with a SSL
Web-mangle that allows us stuff things in theSSL session.
SSL VPN (Anyconnect) Client is a client of complete tunneling using SSL/TCP, which installs an application on the computer and
envelopes vpn traffic in the ssl session and thus also an assigned ip address has the
tunnel's two-way, not one-way. It allows for the support of the application on the
tunnel without having to configure a port forward for each application.
AnyConnect is a client of new generation, which has replaced the old vpn client and can be used as long as the IPSEC vpn ssl.
For anyconnect licenses please see the link below:

ASA 5520 - SSL VPN (Anyconnect) licenses
Hello
Can someone clarify for me the SSL VPN/AnyConnect for the ASA 5520 license? Specifically, the differences between the AnyConnect Essentials and AnyConnect Premium. Our current license looks like this:
The devices allowed for this platform:
The maximum physical Interfaces: unlimited
VLAN maximum: 150
Internal hosts: unlimited
Failover: Active/active
VPN - A: enabled
VPN-3DES-AES: enabled
Security contexts: 2
GTP/GPRS: disabled
SSL VPN peers: 2
Total of the VPN peers: 750
Sharing license: disabled
AnyConnect for Mobile: disabled
AnyConnect Cisco VPN 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: disabledThis platform includes an ASA 5520 VPN Plus license.
I guess that means that we have just the 2 'free trial' SSL VPN licenses and nothing else.
I would like to add 25 or maybe 50 SSL VPN licenses and be able to use a combination of full free client, thin client and groups client AnyConnect. The 'ASA5500-SSL-25' (or 50) would be the correct license I need to buy?
Thank you
Rob
Hello
The essentials license is per device and does not allow full-tunnel.
If you need other features like Secure Desktop, without client SSL and other optional features such as shared licenses, you must go to the Premium license.

Is that correct, or is at - it an easier way to do this without having to add all statements of NAT? Moreover, any change would be to do on the access list?
Hello
To my knowledge you should not create several new instructions from NAT. You should be well just create a new Group 'object' for new addresses your source address NAT.
To better explain, take a look at your current ' object-group ' that defines your source addresses
the APP_CLIENT_Hosts object-group network
network-object, object SITE1_APP_JCAPS_Dev_VIP
network-object, object SITE1_APP_JCAPS_Prod_VIP
network-object, object SITE2_APP_JCAPS_Dev_Host
network-object, object SITE2_APP_JCAPS_Prod_VIP
network-object, object SITE1_APP_PACS_Primary
Now you can do this sets up a "object-group" that contains a NAT IP address for each of the IP addresses inside the ' object-group ' and 'object' used above. The IMPORTANT thing is that the ' object-group ' that contains the NAT IP addresses is in the SAME ORDER as the actual source addresses.
I mean, this is the first IP address is in most object - group ' will correspond to the first IP address in the newly created "object-group" for the IP NAT addresses.
As above, you can simply have the same "nat" configurations 3 as before but you change/add in the newly created "object-group"
For example, you might do the following
network of the SITE1_APP_JCAPS_Dev_VIP_NAT object
Home 88.88.88.81
network of the SITE1_APP_JCAPS_Prod_VIP_NAT object
Home 88.88.88.82
network of the SITE2_APP_JCAPS_Dev_Host_NAT object
Home 88.88.88.83
network of the SITE2_APP_JCAPS_Prod_VIP_NAT object
Home 88.88.88.84
network of the SITE1_APP_PACS_Primary_NAT object
Home 88.88.88.85
the APP_CLIENT_Hosts_NAT object-group network
network-object, object SITE1_APP_JCAPS_Dev_VIP_NAT
network-object, object SITE1_APP_JCAPS_Prod_VIP_NAT
network-object, object SITE2_APP_JCAPS_Dev_Host_NAT
network-object, object SITE2_APP_JCAPS_Prod_VIP_NAT
network-object, object SITE1_APP_PACS_Primary_NAT
Then you add the following configurations of "nat"
NAT (inside, outside) 1 static source APP_CLIENT_Hosts APP_CLIENT_Hosts_NAT CLIENT_Host_1_NAT CLIENT_Host_1 non-proxy-arp-search of route static destination
Static NAT APP_CLIENT_Hosts APP_CLIENT_Hosts_NAT static destination CLIENT_Host_2_NAT CLIENT_Host_2 non-proxy-arp-search of source route 2 (inside, outside)
NAT 3 (indoor, outdoor) static source APP_CLIENT_Hosts APP_CLIENT_Hosts_NAT CLIENT_Host_3_NAT CLIENT_Host_3 non-proxy-arp-search of route static destination
Note line numbers, we added the above commands. This allows them to enter the upper part of the ASAs NAT rules, and therefore, they will become active immediately. Without line numbers that they will only be used after when you remove the old lines.
Then you can remove the "old"
no nat source (indoor, outdoor) public static APP_CLIENT_Hosts APP_CLIENT_Hosts CLIENT_Host_1_NAT CLIENT_Host_1 non-proxy-arp-search of route static destination
no nat source (indoor, outdoor) public static APP_CLIENT_Hosts APP_CLIENT_Hosts CLIENT_Host_2_NAT CLIENT_Host_2 non-proxy-arp-search of route static destination
no nat source (indoor, outdoor) public static APP_CLIENT_Hosts APP_CLIENT_Hosts CLIENT_Host_3_NAT CLIENT_Host_3 non-proxy-arp-search of route static destination
This should leave you with 3 configurations "nat" who made the NAT source addresses and destination.
Naturally while you perform this change you will also have to change the ACL Crypto to match the new source NAT. This is because as all NAT is done before any VPN on the ASA. So the destination addresses are Nations United for before VPN and source addresses are translated before VPN.
If you do not want to make the changes without affecting the connections too so I suggest
- Add rules to the ACL Crypto for new addresses (NAT) source. Of course, this must be done on both sides of the VPN L2L. You would still be leaving the original configurations to the Crypto ACL does not not the functioning of the L2L VPN.
- Add new configurations of "nat" above without the line numbers I mentioned who mean you that they wont be used until you remove the "old".
- When you are ready to be migrated to use the new IP addresses, simply remove the original "nat" configurations and the ASA will start the corresponding traffic for new "nat" configurations. Provided of course that there is no other "nat" configuration before the nine that could mess things up. This should be verified by the person making the changes.
Of course if you can afford a small cut when then changing the order in which you do things should not matter that much. In my work, that connections are usually not that critical that you can't make these changes almost at any point as it is a matter of minutes what it takes to make changes.
Hope this made sense and helped

Restrictions of ASA Anyconnect for Split Tunneling network list
Hello
I have a question. We use Cisco ASA 5520 9.1.1 firmware version with configure SSL VPN Anyconnect(Anyconnect client version 2.5.605).)
We use the big Split Tunneling access-list with 200 ACEs.
If I add more than 200 entries in the list of access and then I connect to the VPN, and after that, we will see that only 200 entries have been added to the routing table.
So my question is... There is a limit for Split Tunneling ACL when you use the Anyconnect client?
Thank you
Hello
This is very well document in one of internal bug at Cisco . Unfortunately, as it is internal I will not be able to share the same with you. The only workaround available as of now is to combine your networks and make the list as small as possible covering all the required network you need which is less than or equal to 200
Thank you

Help please - configuration VPN AnyConnect crossed
Hi there, forgive me if I missed all the protocols forum because this is my first post.
I am trying to configure an AnyConnect VPN and I think it's nearly there, but not enough yet. When I connect from an outside network, it gives me the following error '... No address is available for an SVC connection. I checked the pools of addresses and what I see, they are assigned to the profile. I'm doing it also crossed, I all VPN traffic through this router... traffic LAN and remote Internet sometimes when I'm on the unfamiliar wifi hotspots. I tried to get this to work for more than 1 week with a lot of different forums to scouring. I have included my config running for anyone to help me with. I appreciate a lot of the answers to get me on the right track. Thank you.
Update 15 minutes later: I posted my SSLVPN IP pool to the DefaultWebVPNGroup and it connected but I was unable to browse the web or ping network resources. I would like to disable the "DefaultWebVPNGroup" without any consequences for the installation program. What I still have to disable?

Thanks again to all.
To access the internal resources of VPN, here's what needs to be configured for NAT:
obj-SSL-pool of network objects
192.168.132.0 subnet 255.255.255.0
object obj-Interior-LAN network
192.168.123.0 subnet 255.255.255.0
Static NAT obj-Interior-LAN obj-Interior-LAN destination source (indoor, outdoor) obj-SSL-pool static obj-SSL-pool
I also advise you to remove the following statement of the NAT:
NAT (exterior, Interior) source Dynamics one interface
If you want all traffic internet VPN to be routed to the tunnel, then here's the NAT config:
object obj-SSL-internet network
192.168.132.0 subnet 255.255.255.0
dynamic NAT interface (outdoors, outdoor)
And finally, you cannot disable the group policy by default 'DefaultWebVPNGroup '. So that when you log-in, you chose
SSLVPN_users group of tunnel, which will apply SSLVPN automatically group policy that you have configured explicitly that.
I hope this helps.

Restrict access VPN client on IOS 12.4
I'm trying to restrict access to the client VPN ports for the specific customer VPN leading to a router in 1841 running IOS 12.4 (9).
With versions of IOS of pre-12, 4 that this could be done by using the ACL on the outside, but with version 12.4, it seems that VPN connections are allowed even without a declaration of "permitted" in the external ACL (similar to "sysopt connection permit-ipsec" on the PIX).
Is it possible to limit the VPN traffic on the external interface of the client?
See you soon,.
Christoph.
Hello
The feature you're looking for is called:
Access check crypto on plaintext packets
Check it out in the Configuration Guide for Cisco IOS, version 12.4 security
In sort, set the encryption to your ACL post, go into your crypto-map and apply it with:
set ip access-group {access-list-number | access-list-name} {in | out}

Restrictions of VPN concentrator
We use an all 3000 series concentrator some users access to a part of our network.
It has been implemented to allow the PC to communicate with our private addresses (class B).
I need access to a couple of IP internally (within the class B).
Is it possible to refuse access to these IP specifically, or should I go and completely re - build the lists allow?
To do this, the most consistent is to use filters and rules to deny traffic to these IP addresses, click on the following link for it:
http://www.Cisco.com/en/us/docs/security/vpn3000/vpn3000_47/configuration/guide/polmgt.html
Create rules and add them to a filter that can then be applied to the group that these clients are connecting to.
On a different approach, if these vpn clients use the TunnelAll like politics of split tunnel, you can modify the policy to be "exclude the networks in the list in order to bypass the tunnel" and use a list system (which will contain the restricted hosts), and where the traffic is provided for guests, the VPN client will not tunnel traffic. FYI, this will send traffic for guests with this policy of TUNNEL from SPLIT to be sent the text, not routed, but sent in plain text by the vpn client.

Clients vpn AnyConnect and cisco using the same certificate
Can use the same certificate on the ASA client Anyconnect and cisco vpn ikev1-2?
John.
The certificate is to identify a user/machine rather than the Protocol, then Yes, generally 'yes' you can use the same certificate for SSL/IKEv1/IKEv2 connections.
What you need to take care of, it's that said certificate is fulliling Elements of the Protocol, for example implmentations IKEv2 is 'necessary' particular KU are defined and client-server-auth/auth EKU are defined on the certificates.

Tunnel VPN AnyConnect w/certificates IKEv2
We have an ASA5525 that we strive to use to create a VPN tunnel using certificates. For now, the ASA will be CA. It seems that we have successfully downloaded the cert to the customer. Our network is quite simple. ASA is 10.0.0.1 outdoors and the client to 10.0.0.3. The client connects via a switch outside the VPN. That part works.
The requiement is for the customer to authenicate using only a cert. Debugging, it is apparent that cert withdraw ok. When trying to connect the customer (AnyConnect V3.1) receives a pop up when selecting a group when the group is selected, connection is refused for the unauthorized connection mechanism. We try to use IKEv2. Please note that we are using a beta version of the code for the SAA. I have attached a log of our attempt, a 'performance show' and a 'version '.
Thank you
Douglas
Douglas,
If it works, right?

ASA5505 management via VPN/Anyconnect without group
I have 2 questions about the configuration of the SAA.
The first is related to the SSL VPN configuration. Just one group of users to which you connect to our main office via remote access. Is there a way to configure SSL VPN to not display a group selection?
I have the omission of the list of the groups-tunnel-enable command and configuration group on user accounts locking, but neither work.
Secondly, I am at a loss on how to configure ssh to allow users connected via VPN connections. I guess:
SSH 172.16.1.0 255.255.255.0 inside
with 172.16.1.0 24 is the ip pool assigned to remote access vpn users would do so, however, it's a no go. How can users of remote access (which are for the most part, all technicians) granted the possibility to connect to the device?
Thanks for your help.
To be able to manage the ASA via SSH via a VPN tunnel, you will need to enter the configuration command "in man".

A remote VPN (link source and destination ip peer)
Hi all
I can access my thought of networking Office RAS VPN I have a static ip address on my home modem, now I want to create an access list, so I should be able to access to my office network through this static ip address only, I tried with given below ACL on my desktop firewall, but it did not work for me.
Example access-list 101 permit interface host 10.0.0.1 udp outside eq 500
access-list 101 permit interface host 10.0.0.1 esp outdoors
Access-group 101 in external interface
Any idea,
Thank you inadvance
Concerning
Tash
Hello guys,.
Tash, so say you now you have purchased a static IP address for your home, and now you want your ASA to accept than intellectual property. you use the Cisco VPN Client right?
Amatahen, you have reason sysopt connection permit VPN will allow encrypted traffic to bypass the access-group, but is not encrypted but the traffic of negotiation, because it's we´re AM going to use 3 packets (UDP 500, but if any side is at the origin of the package NAT #2 and #3 will move to UDP 4500 instead of 500)
Filter access group by-the-box traffic is NOT employment traffic so to achieve, you need to create a group of access to your home IP but the thing, it is that your group access must be configured with the keyword for control-plane at the end., you'll also need to allow ssh, https, etc., depending on the services you run on this device.
Kind regards
