• WebVPN client SFR module removes the http packets

  Hi, I have configured the WEBVPN access to ASA 5512 with SFR module a long time ago and internal http links have been working great.

  After the ASA upgrade to 9.5 (2), module of firepower to 6.0.0 - 1005 and DefenseCentar to 6.0.0 (build 1005), I am unable to open the internal http links (also CIFS works very well at the same time).

  After I connect to the WEBVPN, try to open "http://192.168.4.3" and then go to the monitoring of the ASA, I see these newspapers:

  6 August 5, 2016 19:11:32 302014 192.168.4.3 80 172.16.1.2 13215 connection disassembly of the TCP 5709589 for Internal:192.168.4.3/80 to identity:172.16.1.2/13215 duration 0:00:21 bytes 0 TCP Reset-O

  172.16.1.2 is internal IP address of the ASA and 192.168.4.3 is the internal web server.

  If I stop with forwarding traffic to the SFR module all work very well. I checked on DefenseCenter access policy, traffic is allowed I can see in the connection events.

  Have no idea what might be a problem here?

  Y at - it a debugging option more detailed why SFR removes these packages?

  Thank you!

  Hi Nele,

  I think you might be hitting a bug.

  I understand that you have an authorization for this traffic rule. But can you please create a rule to trust the IP address of the ASA for internal services that should be available in your access control strategy.

  Now, check if the traffic still gets deleted.

  Thank you

• WebVpn and enter URL

  I use an ASA and WebVPn. It all works well, but on the left side of the WebVpn page. I can enter in any url I love and get on this side, internal or external. Is there a way to delete this box where you enter a url.

  Most likely you have entered

  ASA(config-Group-WebVPN) functions entry url file-access - the entry of the file file-navigation

  No it takes the url entry to remove the toolbar from the url.

• failed the WebVPN login

  Hello world!

  I'm setting up a asa 5520 (software Version 8.2 (5)) connection without customer serveral profiles and ACS 5.3 as server authentication, this works well AD users or local can connect vpn without problem, but now I need to show only one (common to all) profile on the portal of the ASA and behind the stage allocated to the connection profile right according to the profile of the user authorization I followed the following document

  'Lock group VPN using ACS 5.x.pdf', but it does not work as expected, it continues to show "cannot connect".

  So I took a glance at the ACS on radius authentication and the user is authenticated, I did a debug aaa 255 common, debug all the RADIUS

  everything seems to be ok, but when I use debug webvpn 255

  It gives me the following message

  Jonathan,

  The question is clear, your users do not connect to the right profile.

  Please see this:

  ASA 8.x: allow users to select a group when connecting WebVPN with Group Alias group-URL method

  The idea of having the authorization of GBA is to affect a specific group depending on probably the attribute Radius 25 policy, but if you have it working in conjunction with the 'group-lock' feature, then you must ensure that users connect to the correct connection profile, group policy does not allow the connection.

  For example:

  test group policy attributes
  

  Group-lock testGroup
  

  !

  tunnel-group testGroup General attributes
  

  Group Policy - by default-test

  !
  

  testGroup webvpn attributes tunnel-group

  Group-url https://1.1.1.1/testGroup enable

  So if a user connects to a different profile that is not the testGroup and gets group policy named test, then the connection will be rejected.

  HTH.

• Authorization of RADIUS WebVPN ASA

  Hi, guys.

  I'm working on an ASA 5510 and plan to work as a waiter webvpn. Currently I am facing a Raius permission problem.

  I can't config Raiuds AV pair in ACS server to designate the webvpn different policies for each group of users.

  Until I have it configured on the router to IOS, and it might well work.

  How can I understand this? Anyone have any ideas? ASA does not support the webvpn radius av pair? Thank you.

• WEBVPN and AD group membership

  I desperately need some advice with my design of authentication of WEBVPN.

  How to restrict specific users to connect only to certain profile connection alias?

  For example. Let's say I have the GROUP A and GROUP B GROUP C as an alias, available in the drop down below to the SSL login screen. In AD, I have 3 groups of security, the same. How can I make sure that only members of the group a security group can authenticate to the GROUP a connection profile and not the others. Ideally, I'd like to achieve with the Radius Authentication, but I couldn't find an attribute that has been passed along that I can pre-selection against. Any suggestions are appreciated. Thank you.

  You can use the ldap mapping to authenticate your users against AD with ldap and retrieve the memberOf and this value map to the value of the IETF-class which includes the SAA this to activate Group locking, allowing only users belonging to a specific tunnel group strategy to connect to this strategy of tunnel group.

• WebVPN and remote VPN access

  Hello

  Is there a difference between WebVPN and remote VPN access or they are the same.

  Thank you.

  access remote vpn consists of

  -IPSEC VPN remote access. It is part of the ASA, no permit required, requires pre-installed Client from Cisco VPN IPSEC on PC

  -with AnyConnect SSL VPN remote access. It requires licensing of SSL VPN on SAA. AnyConnect client can be installed automatically on the PC with the launch of web.

  -with Essentials AnyConnect SSL VPN remote access. Beginning with ASA 8.2 (1), almost license $ 0. It's the same AnyConnect client as in the previous article, but it cannot be installed automatically with the launch of web. It must be previously installed as of Cisco IPSEC VPN client.

  -webvpn aka clientless vpn. It is a portal HTTPS which allows HTTP connections, file sharing, telnet, RDP and much more (with smart tunnels) resources without having to install a real client on the PC. It requires licensing of SSL VPN on SAA. It cannot be used if "AnyConnect Essentials" license is activated on SAA after 8.2 (1)

• ASA - logging URL enter WebVPN

  We have a Cisco ASA and use it for multiple WebVPN (aka SSL VPN) connections.

  Based on the URL, they are placed in different profiles of group. For example https://asa.mydomain.com/test will put them in the Test connection profile, while https://asa.mydomain.com/prod is put in the Prod connection profile.

  It works very well, however, we would like to be able to connect (ASA journal) the exact URL used to start their user session. Is this possible?

  It is not possible. If I had to guess without seeing your config, you use only group URL rather than the alias and the drop-down selection list. In a case like this, users accessing the FQDN such as http://vpn.yourcompany.com uses by default the connection DefaultWebVPNGroup profile. If there is no limit session configured on this policy and authentication is configured the same, then the user may access. You can use the DefaultWebVPNGroup as a catch all and set the concurrent connection to 0 in the policy to restrict access. A better approach would be to seek locking group.

• Enable WebVPN without granting access to the ASA/AMPS/CLI

  Is there a way to allow access to users WebVPN (SSL) through the ASA (8.2.1) without allowing them to connect via ASDM, SSH, Telnet or CLI? I want to warn my VPN users to access the configuration of the firewall.

  I see in ASDM there are certain formulations on "it's effective only if AAA authenticates command console is configured" but I do not understand what it is explained.

  Thanks in advance,

  Greg

  You can restrict local users with the following:

  name of user attributes

  type of remote access service

  You need aaa authenticate console orders because when its not defined you can come as the default username (pix) or no username at all and the password enable (in the case of Deputy Ministers DEPUTIES). If there is no sent username, so we cannot verify obviously not the option of type 'service' in the attributes of user name. Here is more information on the command "aaa authenticate console":

• WebVPN file download problem

  Hello world

  I have an ASA5520 with active WebVPN ASA 8.21 is software version.  I have users of webVPN login and need to download files from a cifs share.  Users successfully connect and gain access to the share.  However, it seems that when a file is greater than 2 GB, the download does not complete.  The download stops each time than 2GB.  If I log on locally and ride sharing, I can successfully download the entire file over 2GBs.    Is there a download through the WebVPN file limit?  Any other ideas of what could be the cause?

  Thank you

  Scott

  There are a few legacy group policy controls that allow you to restrict download, view, and download files.  What I read, I do not believe that these commands are hooked into the burner without ASA 8.x client.  I have this model in my lab to see if it really affects the max download file size.

  Hello

  Make sure that you have the list of nat source configured to allow the VPN pool, if you want to use internet from the router or you can use split tunnel to allow only internal traffic on VPN

  example:

  SVC split Router (config-WebVPN-Group) # include 198.168.100.0 255.255.255.0

  SVC split Router (config-WebVPN-Group) # include 192.168.200.0 255.255.255.0

• 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:

  http://www.Cisco.com/c/en/us/TD/docs/security/vpn_client/AnyConnect/ANYC...

• SSO with WebVPN ASA using RSA tokens

  Current configuration:

  Chip & PIN the user authenticates for-> ASA5510 8.2 Clientless VPN-> past to the 7.2 SDI RSA Authentication Manager.

  I've got of authentication works great, at the first connection, users can connect with their AD usernames and RSA tokens and generate his pin code.

  We used to use ACS express and their advertising information for vpn authentication, but now we have to two factors of authentication.

  Is it possible to some how to maintain SSO so that when the user authenticates via its RSA token they can always browse through OWA, Sharepoint, CIFS (file share) without having to enter their credentials for the AD?

  Any help or information is much appreciated.

  Thank you

  You can activate the field "internal password" on the customization of WebVPN and also re-name-the ("Password AD" for example) and then configure the entries in the auto-code of access for internal URLS on NTLM.  Such that when the guest servers the WebVPN session will send the user name used to connect to the ASA but send the internal password captured during the connection instead of the password used to connect to the WebVPN himself.

  The only problem I saw during the test, there is no seam to be a graceful way to establishing a password incorrect or missing, then NTLM would fail and fall back basic over ssl.   Finally it would block the AD accounts based on URL how much the user has tried when the password entered when the connection is bad or missing (because it failed to connect to the WebVPN).

• WebVPN and Anyconnect?

  Is it possible to get WebVPN (i.e. without customer) and AnyConnect on the same interface? Whenever I have activate AnyConnect, even with another port, he sweeps my bookmarks and the elements that I have currently defined in the page without client.

  Assuming that your profiles and groups are configured correctly, the only other configuration that can force you to AnyConnect as default would be your configuration of dynamic access policies.

  Check if you have more than one DAP configured, otherwise, check the default DAP strategy.

  -Go to the tab "Access method" to confirm the option set to "unchanged".

  If you have more than one DAP configured, you need to comb your configurations of DAP to see which is used, or check your logs.

  The DAP will force you to use AnyConnect, Clientless default AnyConnect or default to Clientless.  DAPs are a boon and a burden.

  Dynamic access policies can be configured for access to the network (Client) or clientless SSL VPN access sections of the ASDM.

  If you are still experiencing a problem, CLI for your firewall post regarding the community to consider your WebVPN configuration.  That's all for the most part in the second case of the configuration.

  In addition, if authenticate you LOCAL, make sure that the user configuration is set to legacy.  I hope you havn't hardset the user to a particular group policy.

  FYI - application of the policy is in the following order:

  DAP-> user uploading-> Group-> Group Policy policy w / profile of fitting-> attributes of default group policy
