• ASA5505 with 10 users. Need to connect 25 remote users with AnyConnect Client

  Hello to everyone.

  I ASA5505 with license 10 users. I need to connect 25 remote users via SSL VPN (in my case cisco Anyconnect client). So I have to buy the license more security (ASA5505-SEC-PL =) for more then 10 simultaneous VPN connections on Cisco ASA 5505. Fix?

  And the main question. What I need to order the user getting up-to-date (for example ASA5505-SW-10-50 =, or ASA5505-SW-10-UL =) license for my device Cisco ASA5505 in order to have 25 connections of concurrent remote users without restriction for each remote user?

  You need the license SecPlus for increased remote access users. But you don't need an extra user license if you still only up to 10 internal systems.

• Problems of NAT with AnyConnect and 8.3 of the ASA

  I have set up on an ASA 8.3 AnyConnect.  I'm properly connect and pulling an IP from the pool that I created.  The problem I have is that I'm quite see "receive" packets in the AnyConnect details.  I know about the ASA 8.2 and earlier you would use a "waiver" NAT to do the translation of the identity.  How is what is done with 8.3 and later?

  Within 8.3 and later networks are defined as objects using groups of objects. Then, these groups of objects are referenced in the NAT statement to define both pre and post NAT (real / mapped) addresses.

  network of the LOCAL_LAN object
  Subnet 192.168.0.0 255.255.0.0

• IOS router VPN Client (easy VPN) IPsec with Anyconnect

  Hello

  I would like to set up my router IOS IPsec VPN Client and connect with any connect.
  Is it possible to configure an IPSec and SSL VPN Client on IOS router? I use for example a 1841.

  It would be perfect to give the user the choice of SSL or IPSec protocol. And the user needs that the Anyconnect Client.

  I think it's possible with a Cisco ASA. But I can also do this with an IOS router?

  Please let me know how if this is possible.

  Also is it true that the IOS routers are not affected to hear bug bleed? SSL VPN and SSL VPN with Anyconnect page is also save?

  http://Tools.Cisco.com/Security/Center/content/CiscoSecurityAdvisory/CIS...

  But I am in any way interested in using IPSec and SSL VPN on a router IOS...

  It's true - CCP does not yet offer the options to configure a VPN IPsec with IKEv2.

  The configuration guide (here) offers detailed advice and includes examples of configuration.

• AnyConnect Clients cannot communicate with each other

  I have a problem that I've been pulling my hair out... my teleworkers connect to our network of Corp. via a connection AnyConnect VPN (version 3.1) to a Cisco ASA5520. I have not split tunneling enabled for this profile, so that all traffic should pass through the tunnel and all guests are in the same subnet L3... as far as their IP VPN address goes. The problem is the teleworker PCs cannot communicate with each other (pings/RDP/etc.). When I look at the newspaper I see traffic from one to another, have denied anything, but they do not communicate. My Network Corp., I can communicate with the two PCs Anyconnect very well. When I go to monitoring. ASDM itineraries I see each host that is connected to the ASA via Anyconnect, and the gateway for each is the default gateway of the SAA.

  Am I missing some setting in the VPN profile that prevents the access between these hosts? I think that something come in the newspaper...

  Have you enabled crossed and also a free NAT between AnyConnect users?

  permit same-security-traffic intra-interface

  network of the AnyConnect_users object

  subnet

  public static AnyConnect_users AnyConnect_users destination NAT (outside, outside) static source AnyConnect_users AnyConnect_users

  If this does not resolve your problem, please post a sanitized complete configuration of your ASA.

• AnyConnect client cannot access external sites

  I am installing AnyConnect VPN with no split tunneling. ASA 5505 v8.2. It seems that it should be really easy. I must be missing something.

  I can get AnyConnect users to connect very well and they can access internal sites and on other sites in IPSec tunnel. But no access to internet.

  Internal 10.1.1.x pool VPN is 10.1.1.251 - 253 (list of Temp for the test). I have published the following plotter:

  packet-tracer input outside tcp 10.1.1.253 12345 69.147.125.65 80 detailed
  

  The last reported point (where it fails) is:

  Phase: 7
  Type: WEBVPN-SVC
  Subtype: in
  Result: DROP
  Config:
  Additional Information:
  Forward Flow based lookup yields rule:
  in  id=0xda7e9808, priority=70, domain=svc-ib-tunnel-flow, deny=false
  hits=364, user_data=0xcb000, cs_id=0x0, reverse, flags=0x0, protocol=0
  src ip=TempVPNPool3, mask=255.255.255.255, port=0
  dst ip=0.0.0.0, mask=0.0.0.0, port=0, dscp=0x0
  

  Which means by SVC-WEBVPN?

  A relevant config:

  No ACLs, filters or limitations of policy group on HQ customers.

  Security-same permit intra-interface

  Global 1 interface (outside)

  On advice, I've added: nat (outside) 1 10.1.1.0 255.255.255.0, then I can get no tunnel guests outside guests, but then no IPSec.

  Kind of a weird, that with this, the tracer of package does not change. Continue to deny shows, but the site is accessible.

  When you say tunnel IPsec sites... is that the tunnels IPsec Site to Site on the SAA?

  The command:

  NAT (outside) 1 10.1.1.0 255.255.255.0

  It should allow the AnyConnect customer pool for PATed to Internet.

  If you need clients AnyConnect to access the Internet and the access to remote IPsec tunnels as well, you can do it with policy NAT:

  access-list anyconnect deny ip 10.1.1.0 255.255.255.0 x.x.x.x

  access-list anyconnect deny ip 10.1.1.0 255.255.255.0 y.y.y.y

  access-list allowed anyconnect ip 10.1.1.0 255.255.255.0 any

  NAT (outside) 1 access list anyconnect

  Global 1 interface (outside)

  With the above configuration, you are bypassing NAT for AnyConnect customers when they want to access remote sites through the IPsec tunnels (assuming that x.x.x.x and y.y.y.y for remote networks through these tunnels).

  And the rest of the AnyConnect (10.1.1.0/24) pool will be PATed to Internet.

• RDP fails to connect with anyconnect

  Hi all
  I have a problem with the configuration of an ASA 5505
  When my users connect with anyconnect they can only connect to the server, but when they want to connect to their own pc, it does not connect.
  When they are connected, they can ping their own pc even with the DNS name.
  When I let connect them trough the clientportal. They make RDP on their own pc.
  NAT is set to the ip address of the server as well as the pc owners.
  The server is a victory of 2008 SBS and clients are Win XP
  Anyone have an idea?

  Please indicate the following:

  Can you ping 192.168.1.14? and can try you to telnet to port 3389 to 192.168.1.14 invites back?

  In addition, if the connection that allows 192.168.1.14 different IP subnet RDP to the server? Is there a PC firewall that would block access? You can try to disable the Windows Firewall on 192.168.1.14.

• AnyConnect Client AnyConnect communication

  Hello

  We have users that are connected via AnyConnect that cannot communicate with each other using their software phones during extension call. They can communicate with each other when using 7 digits well. They use Split tunnel and we have unchecked network list under the internal policy of the Group and added the AnyConnect subnets. They can call for any other network but network AnyConnect. Is there a defect that does not allow AnyConnect AnyConnect communication?

  Also, I got their firewalls, turn to users and they still couldn't call or ping or tracert.

  Is it possible for a client AnyConnect ping on another AnyConnect client that is on the same subnet?

  Any suggestions?

  Thank you, Pat.

  You can remove the following because it is not necessary ("clear xlate):

  NAT (outside, outside) static source AP-SSLDHCP destination interface static any_vpn any_vpn

  It's OK that the OSPF is advertising and redistribute, so not know internal OSPF routers to send the 10.3.8.0 subnet to the ASA.

  And when I say roads that overlap, I mean when you have for example 10.3.8.0/21 pointing inward, you need to configure more specific routes (10.3.8.0/22) pointing outward. Otherwise, it's going to be routing inwards and the loop since the supposed to exist outside vpn pool. Routing should be good, because you can access internal networks, so I wouldn't change anything regarding the roads.
  

• Error in installing AnyConnect Client

  During his installation of Cisco AnyConnect Secure Mobility Client, I got the error: "VPN client agent could not create the filing of interprocess communication."

• Automatic demotion of the Anyconnect Client (router IOS)

  Hello

  We run a Cisco Anyconnect client with a router IOS environment (2921) as the lead aircraft.

  We have upgraded the client package on the router to the latest version 3.1.13015. After installing this package on the customers, we discovered a bug. Windows-based computers are not able to establish a VPN connection more (authentication and auto-package-level still works, but then an error message is displayed ("unable to cannot" or similar).)

  I returned the package on the router back to an older version (3.1.11004), but is not beeing auto-installe when a client with the new version (buggy) connects.

  Is it possible to configure the router to force a downgrade to the customers, or is the only way to workaround to manually uninstall the package on clients?

  Thank you

  Heinz

  No you can't auto-downgrade the station clients.

  Unfortunately, you will need to uninstall it from the client end, then get the right package (older) of the router.

  Hello

  I have a problem with the local domain name resolution when connected via a VPN SSL using anyconnect.

  I've identified it is due to the fact that the assigned DHCP DNS is not by adding a domain suffix.

  I proved this by adding the local domain after the host name, I'm ping.

  On the the ASA5505 ASDM I ensured that the appropriate field is identified on the DNS, but this still does not work.

  Please could someone guide me in the right direction. It should be on the profile that is downloaded or a configuration that automatically adds the correct suffix when DNS queries are sent to the DNS server.

  Hi again,

  I just figured my DNS suffix name resolution problem and I thought I'd share my solution in case it helps you:

  • Connect to ASDM, select VPN remote access, expand access to the network (Client), highlight the group policies.
  • On the right, edit the group policy that you connect your remote users.
  • Screen that comes up, highlight the server on the left and then click on the small arrow to the right to display other editing options in group policy.
  • Fill in the default domain with your internal domain name (for example, mydomainname.local)
  • Click Ok to save and save config to Flash running.

  Test of reconnection to with a client AnyConnect and performing a ipconfig/all.

  For me, I can now see the suffix dns that I defined in the group policy and successfully, I can ping internal hosts by name.

  Good luck!

• Mobility AnyConnect client configuration suggestions

  We used IPSEC VPN 30XXs and ACS 4.3 (or 4.2?) with the former VPN clients but with Windows 10 years we can do is more work. Time for Anyconnect.   We have a few ASA 5510 / 5520 s with the Anyconnect Premium peer support so that we can move out of IPsec. I have it works using TLS with CAS but I think we need a new version of the AAA server too.

  Questions... What is the way better / cheaper to use a bit of a two-factor authentication. Currently it seems using GBA only a user name and password (no user/psw group) is used to authenticate in. A cert paid on the 55xxs to avoid the problem of security is not a problem, but for each client CERT would be cumbersome to manage. ICS seems to be the way forward for the management of users unless there is a compatible more easy/less expensive product.

  Directions of the best way to go would be appreciated as there seems to be a lot of options - all at additional costs. We want a complete IP connectivity that we have with IPsec, since we also have Citrix GW for specialized connections.

  The only options interested is to check for a virus protection service. We do not allow tunneling split for users allow I got it during the test (Split tunneling only for admin users).

  We'll stay with Anyconnect 3.x since it's free and supported for 3 years more than what I read. AC 4.x seems to involve extra cost of client of what we currently have.

  Thank you!

  If you're handy with Windows server and want to stay on the road of low cost, issues the certificates users using CEP through the ASA proxy protocol. Then their certificate issued is the first authentication method, and the second is their password.

  You can even set the ASA to remove the user name of the certificate automatically and prevent the user from typing in anything else if you so desire.

  Take a look at the Cisco Live presentation "BRKSEC-3053 practical PKI for remote VPN access" San Diego 2015. It is a very complete guide for this operation (and the use of EHT as well).

• SSL VPN without disabled in ASA5505 after the Activation of the AnyConnect client

  Hello everyone,

  I am facing a problem with the VPN service in ASA 5505. Initially, I was using SSL VPN without customer who was working absolutely fine, no problem. Recently I bought AnyConnect Essentials License with license AnyConnect VPN, Mobile (for focusing on the Client SSL VPN Service for desktop and mobile respectively) and have activated these keys inside of the firewall. After that I may be able to connect to based on the VPN Client, using the AnyConnect client. Clientless VPN access is not allowing you to connect and displays an error (see the attached screenshot).

  I created two VPN profiles Viz, basic (for clientless VPN) and rvsvpn (for client based VPN). Download the AnyConnect Client I can connect to the rvsvpn profile. But if I try to connect using the basic profile, it throws an error has been to what is displayed in the exhibition.

  Please help me in this regard, as what can be done to use both the vpn connection profile. Or what the use of AnyConnect disables client access?

  Waiting for your help.

  Thanks in advance.

  Samrat.

  "Anyconnect essentials" in your configuration command to disable all profiles without customer (as well as other features that require the Premium license).

  Essentials and Premium are mutually exclusive as the performance of duties. You can have both installed licenses, but only use one or the other (and never both at once) in your running configuration.

• AnyConnect client... SSL vs. IPSec

  Hello

  I have a few questions on the Anyconnect VPN remote access.

  The anyconnect client works with SSL or IPSec ISAKMPv2? Y at - it no default or the default method?

  Where you would identify what method you choose? The anyconnect client automatically detects the type (SSL or IPSec)-based VPN server? How does the SSL over IPSec works in this case?  What is new ANyconnect 4.xclient?

  I would say that 90% or more customers use SSL.

  IPsec IKEv2 is used mainly by two categories of people:

  1. those who have need of next gen cryptographic algorithms for legal or regulatory reasons

  2. those who have had lovers, or CCIE candidates configure their VPN (joke - just a little bit)

  Is, when it is implemented correctly, did a good job to secure your traffic.

  The server (for example, the ASA) defines the method and the client that honors due to the associated connection profile that updates / downloads from the server.

  This initial process, even if you have IPsec IKEv2, normally happens over SSL as part of the preamble of IPsec session establishment. Manually, you can eliminate this small, but it is generally more trouble that it's worth.
