  Unfortunately, the "vpn-filter option" under the group policy on the Cisco ASA applies only the VPN filter in the incoming direction and automatically configures the outbound direction. Refer to this link. There is an improvement that has been opened to support VPN filters in each direction, but it is not yet applied.

  The only way I see is to modify the default behavior and configure ASA to submit VPN traffic to ACL interface using the command of not sysopt connection VPN-enabled and then configure ACL interface accordingly. I don't know if it's worth to you.

• Download ACL for VPN users. ACS 4.1 & 1841 router

  Hello

  I have configured the router 1841 as a VPN server. All VPN users get authenticated using RADIUS ACS 4.1

  I need to apply downloadable ACLs by user.

  I configured the Downlodabale ACL ACS. Same ACS event report shows that the ACL is applied to the authenticated user, but traffic is not blocked or past accordingly.

  What is your configuration?

  I think that the more easy to do is to use IPSEC TIV in interfaces, as well as the aaa authorization network and on the radius server, use ip:inacl to the cisco av pair, as

  IP:inacl #1 = permit tcp any any eq 80

  IP:inacl #2 = permit tcp any any eq 443

  ...

• Assign ACLs to VPN clients

  We have a client that VPN in a Pix 515. I inserted the configuration of intra-interface same-security-traffic allowed on the pix so that members of staff who use the VPN would be able to access a specific resource from the public side. What I would do is to continue to use the same-security-traffic intra-interface command permit, but restrict access to other resources to the VPN client. Can I assign an access list to the VPN client allowing 10.10.10.10 everything and refuse all other connections? Where can I insert this in the VPN structure?

  Thank you

  Yes.

• IOS router + VPN + ACS downloadable IP ACL

  I want to use the function "Downloadable IP ACL" 3825-router VPN (OI 12.4 T) in combination with a CBS.

  In many documents and discussions, I read that it is possible to use the DACLs on "devices Cisco IOS version 12.3 (8) T or higher.

  Authentication and authorization by the AEC works and the device gets some settings of the av-pair-feature.

  I have tried several things to apply the DACL as the use of av pairs or ACS "Downloadable IP ACL" function, but nothing works.

  In the debug log, I see that the av pair is transmitted to the device, but it is not used.

  --> Can you tell me, is it possible to use the DACLs on the IOS routers?

  --> How does it work? What can I change?

  --> Is there a good manual to apply it?

  Thanks for your help!

  Martin

  It would be useful to know the PURPOSE of what you're trying to do...

  AFAIR client config mode requires no ACL for filtering short tunnel split ACL... and I have no way to test right now.

  If you want to allow or not some clients access to certain subnets why not investigate tunneling ACL and vpn-filter in combination with ACS split will rather than for the DACL.

• ACL entering for public router VPN

  Hi all

  I set up our VPN router for access to all of our mobile customers. Our private VPN range is going to be 172.16.10.x/24. I have to add ACL allow rules for this range on our ACL entering all inside LANs to facilitate access for VPN users?

  for example int S0/0/0

  IP address 85.x.x.x

  IP access-group 100 to

  access-list 100 permit ip 172.16.10.0 0.0.0.255 192.168.1.0 0.0.0.255

  If I understand it, once the user connects the VPN tunnel to the inside of the interface, so is traffic through the VPN is encapsulated and therefore wouldn't appear as a private IP address?

  All comments are greatly appreciated.

  Paul

  Sorry I mean you should not change outside the acl for vpn traffic for the rest of the things you can do.

  Thank you

• Cisco ASA, connect an IP address on the OUTSIDE of the VPN remote access

  Hello

  I tried to find resources on the net but could not find a solution, then post it here. Maybe someone can help.

  So the problem is that I'm trying to access a server on the cloud for remote VPN access (cisco asa 5510).

  The server on the cloud (54.54.54.54) is only accessible from the outside interface (192.168.11.2) NY Firewall (cisco asa 5510)

  I added some ACE for this in the ACL of VPN tunnel to divide.

  NY-standard host allowed fw # access - list vpn_remote-customer 54.54.54.54

  And I see the road added to my cliet machine after the VPN connection, but still it cannot connect to this server.

  The network INTERIOR, I can connect to the server.

  

  Thanks in advance.

  Hello

  This is most likely a problem with NAT hair/U-turn hairpin.

  Will need to see the configurations or you would need to check yourself

  I don't know what your version of the Software ASA is to be like who determines what is the format of NAT configuration.

  So far, you have confirmed that the ASA VPN configuration provides the VPN Client with the route to the remote server. Then in circulation should be tunnel to the ASA.

  Then, you will need to check the output of this command

  See the race same-security-traffic

  You should see the command in the output below

  permit same-security-traffic intra-interface

  If you do not, you will need to add it. This effect of controls is to allow traffic to enter an interface and exit through the same interface. In your case this applies to Internet VPN Client traffic to the remote server as it between ' outside ' and spell through the 'outside'.

  Then, should ensure that dynamic PAT is configured for the VPN Clients.

  8.2 software (and below)

  You most likely have a dynamic configuration PAT like that on the firewall, if levels of above running software version

  Global 1 interface (outside)

  NAT (inside) 1 0.0.0.0 0.0.0.0

  In this situation if we wanted to add dynamic PAT for a pool of VPN, we would add

  NAT (outside) 1

  This would allow users to use the same public IP address as LAN users, when accessing the remote VPN server

  Software 8.3 (and above)

  Because the NAT configuration format is completely different in the latest software, you could probably just add a new configuration of NAT completely without adding a

  network of the VPN-PAT object

  subnet

  dynamic NAT interface (outdoors, outdoor)

  Of course, its possible that there could be some configuration NAT already on the device which could cause problems for this configuration. If this does not work then that we would have to look at the actual configurations on the ASA.

  Hope this helps

  Let me know how it goes

• 9.0 can a dynamic nat be used via ipsec vpn?

  9.0 can a dynamic nat be used via ipsec vpn?

  We have a vpn and work between asa and when we run traffic through a static nat rule traffic goes over the vpn. When we use a dynamic nat traffic does not get picked up by the ACL vpn.

  We disable the nat rules to switch back and just so, even when we use the same destination to source the result is the same.

  Am I missing something with 9.0 versions of code? If I disable all the nats and pass traffic it goes via the vpn.

  So, it seems that when you use the dynamic nat statement, it pushes traffic to the external interface without looking at the acl of vpn. Please let me know if I'm crazy, I'm a newb on 8.3 zip code.

  Thank you

  Have you included in the ACL crytop natted ip address or range?

  You allowed natted ip address or range to the other end of the tunnel?

• Remote access VPN clients

  Hello

  I've set up IPSec VPN remotely and it works fine. I need access to connected VPN clients, and it does not work. I have already added an entry to traffic allowing sheep ACL from inside my network to the VPN.

  More information:

  Inside of the net: 10.1.1.0/24

  Is it possible to access from my internal network to the VPN users?

  Thanks in advance.

  Best regards.

  VPN users have access to certain servers via the list of Tunnel from Split.

  Marcelo,

  Split tunnel ACLs must be an IP acl, it is not recommended and supported to set the TCP ports on the split tunnel ACL, the vpn client don't interpret this ACl as a lot are interested in IP, TCP ports, and that could cause you a problem. You can change your config to reflect this. Regarding ACL split tunnel, it must contain the server line. networks that this vpn, customers arrive, remind you this is two-way, as you know.

  So if IT supports the IP range is on this vpnExample ACL vpn clients will be able to reach the IT support guys and vice versa.

  I advise you to change your split tunnel ACLs to specific ports to only the desired servers and the presenters what these customers need to achieve.

  Remove the ports out of this Split tunnel ACLs.

  If you need to restrict services for vpn rather clients use VPN filters.

• 8.2 ASA vpn filter for connections l2l

  I have a vpn-filter set to my police L2L. The remote site uses a Cisco 1811 router and the main hub is a Cisco 5580. I already have an acl of vpn-filter in place on an existing L2L connection which works fine. The only question is, when I make changes to the ACLs for add/remove access, I have to reload the whole of the tunnel until the changes take place.

  My question is, are at - it a command to reload the access control without destroying the tunnel?

  Hi Jeffrey,.

  Design whenever there are changes in the attributes of Group Policy (including the vpn-filter, dns ip of victories or vpn-Protocol etc.), you need to reset the respective tunnel while phase 2 is negotiating with the newly added policy. The command to clear a specific tunnel is: -.

  his clear crypto ipsec peer

  For more details on the command, please see the link below

  http://www.Cisco.com/en/us/docs/security/ASA/asa80/command/reference/C3.html#wp2133652

  So, to answer your query wasn't there command is not to reset the access control. There had been such a command you would still back the tunnel to trigger negotiations ipsec with the new group policy settings.

• VPN IPSec S2S problems

  Hello

  I have a headquarters and a remote site and I want to get a VPN site-to site between the two. I have the following Setup on each router. 'Show encryption session' says that the VPN is in the IDLE-UP condition (and my somewhat limited understanding of virtual private networks, this means that the phase 1 of IKE is complete and waiting for phase 2) When you run a "debug crypto ipsec" on the remote site, I get "no ip crypto card is for addresses local 100.x.x.x" and the VPN remains to IDLE-UP. The ACL on the external interface allows the IP of the remote site. I have CBAC running on the external interface of both routers and ACL permits all traffic between the addresses 100.x.x.x and 200.x.x.x. Could someone help me with the config? I have to do something wrong somewhere.

  Thank you!

  Hi Shaun,

  Some comments...

  The QM_IDLE means that the phase 1 is established. (sh cry isa his)

  You should see with "sh cry ips its" that he has put SAs in place for IPsec encryption/decryption of traffic for the phase 2.

  The ACL for VPN (the crypto ACL) should be one mirror of the other (you have "all" on one side and two statements by the other peer network.

  You do NAT, therefore, there should be a 'workaround NAT rule' VPN traffic (to remove the IPsec NAT traffic).

  This should be it.

  Federico.

• Policy NAT for VPN L2L

  Summary:

  We strive to establish a two-way VPN L2L tunnel with a partner. VPN traffic is one-to-many towards our partner, and our partner they need of a many-to-one to us (they need to access a host on our network). In addition, our partner has many VPN, so they force us to use a separate NAT with two private hosts addresses, one for each direction of the tunnel.

  My initial configuration of the tunnel on my grown up side of Phase 1, but not IPSec. Partner ran debug that revealed that my host did not address NAT'd in the NAT policy. We use an ASA5520, ver 7.0.

  I realize that the ACL for the VPN should read:

  access allowed extended VPN ip host 172.20.n.0 PARTNERHosts object-group list

  access allowed extended VPN ip host 172.20.n.1 PARTNERHosts object-group list

  .. . If the NAT was working properly, but when this ACL is used, Phase 1 is not even negotiating, so I know the NAT is never translated.

  What am I missing to NAT guests for 172.20 addresses host trying to access their internal addresses via the VPN?

  Thanks in advance.

  Here is the order of operations for NAT on the firewall:

  1 nat 0-list of access (free from nat)

  2. match the existing xlates

  3. match the static controls

  a. static NAT with no access list

  b. static PAT with no access list

  4. match orders nat

  a. nat [id] access-list (first match)

  b. nat [id] [address] [mask] (best match)

  i. If the ID is 0, create an xlate identity

  II. use global pool for dynamic NAT

  III. use global dynamic pool for PAT

  If you can try

  (1) a static NAT with an access list that will have priority on instruction of dynamic NAT

  (2) as you can see on 4A it uses first match with NAT and access list so theoretically Exchange autour should do the trick.

  I don't see any negative consequences? -Well Yes, you could lose all connectivity. I don't think that will happen, but I can't promise if you do absolutely not this after-hours.

  Hi Florin,

  In the case of remote VPN access, the user must be authenticated by name of user and password or certificates.
  You can deploy authentication certificate based as follows: -.
  http://www.Cisco.com/c/en/us/support/docs/security-VPN/IPSec-negotiation-IKE-protocols/22520-unityclient-iOS.html#router-config

  This will use the certificate for authentication of users and only requires name of user and password.

  Kind regards

• Doubt on the RA aaa using ACS 5.3 vpn user

  Hello

  I'm putting in place of the VPN on 8.4 ASA with 2 - VPNGp1 and VPNGp2. VPNGp1 groups users will access 1.2.3.0/24 and VPNGp2 users will have access to 5.6.7.0/24. User authentication will be done using RADIUS 5.3 ACS.

  On ASA, I configured pools VPN groups, ACL of VPN, IP, tunnel of groups and group for each group strategies.

  GBA, I created vpn-user1 and user2-vpn for each of the 2 groups.

  I don't know if some configurations more must be done on ASA and AC... Do I need to add new users - vpn-user1 and user2-vpn - on ASA, under each corresponding group policy, using the command political vpn-group?  Or I need to do something else on the ACS?

  Finally, how can I configure authorization and accounting for VPN users? I have to do this on GBA or ASA?

  Please advice.

  Thank you.

  Hello

  Authentication using radius aims to centralize user accounts and policies so that you will not have to configure these on the SAA. You must create a group of authentication servers that points to your ACS, then you will have to refer to this group of servers to your tunnel-group for user authentication queries will be forwarded to ACS for authentication. For accounting you will create an accounting server group and also assign to your tunnel group configuration.

  The GBA, you will need to create a network client that is ASA, and the shared secret will be the same. You create an element of authorization policy network who have the permission settings, or you can choose allowed access, which allows authentication succeed without any special authorization.

  You can debug the sessoin using crypto vpnclient 255 debugging to view the authentication stream.

  Using SSL vpn (anyconnect) for these sessions?

  Thank you
