• IOS VPN L2L, placement and discuss best practices

  We install an IOS router VPN on a for L2L 2651XM VPN bundle.

  I am trying to determine the best placement for the VPN router.

  We have Internet BR, then switch outside, Pix, then inside the switch.

  We have installed a card 4 ports in the Pix 515e to provide the DMZ interface, but have not yet configured all interfaces.

  L2L is B2B and we need so our traffic/internal network firewall/NAT.

  I have a switch for the DMZ if necessary for additional PSS.

  I recommend you to place the VPN router outside of the interface on the outside of the firewall. Ending inside the unencrypted VPN interface on port DMZ on the PIX, in this way, you can use the pix to control which internal servers users VPN can connect to.

  This way you can your traffic inside nat, but your VPN traffic to not cross a line of nat. Your VPN users also allow the pix to access your internet connection

  On the VPN router lock the outside as much as possible interface, if the IOS supports the functionality defined firewall and then use it.

• Routing VPN Ipsec

  Morning,

  I have an ASA 5520 of Cisco running 8.4 (5). When to use a VPN ipsec client and it connects to the local network, how the connection interprets her return flights. Currently, I have all my servers pointing to the front door on our old firewall. I have a different gateway on the new Cisco firewall. It is a transitional phase we are permanently than one Cisco ASA 5520 firewall. For testing purposes, we want to test the configuration of the VPN client with our front Radius Server cut us above. Test users must connect to resources on the corporate network. Should I put a route on the old firewall so when packets hit VPN servers they will know how to return to the VPN tunnel or the source and destination address will already be taken into account when the tunnel VPN hits the server, packages will return to the tunnel. The Cisco VPN client does not NAT configuration. Once we feel that the test is passed, we will change the gateway from the Cisco ASA 5520 to match the existing bridge for all resources on the network.

  Information or advice would be greatly appreciated?

  Thank you

  Carlos

  On the SAA, you set up a pool of IP addresses for the client. This pool should be aligned on the subnet boundaries. On your infrastructure (L3 switch or your old firewall), you tricky staric asa for this pool-network. Thereby the packages of answer-VPN-will flow to the ASA.

• Cisco RV042 VPN hub and spokes, connecting spokes question

  Hello

  I have a few Cisco RV042 router and VPN links them with a hub and spoke topology.

  Each speaks VPN works, they manage to connect to the platform.

  The hub can see each VPN active rays.

  A computer under the hub can connect to a computer in any talks.

  A computer under any talks can connect to a computer running the hub.

  Which works very well.

  Now, what I really need, is to connect computers under a RADIUS to connect to computers under another spoke.

  It don't work.

  Current configuration of LAN:

  HUB IP / mask: 192.168.0.1 / 255.255.255.0

  Spoke1 IP / mask: 192.168.1.1 / 255.255.255.0

  Spoke2 IP / mask: 192.168.2.1 / 255.255.255.0

  I was wondering if the Cisco RV042 can be configured to allow that and HOW?

  If we can not do, should what other router I use as a hub? Should I change the rays as well?

  Thank you and have a nice day

  Hope that this document can point you the right direction.

• Hub and spoke VPN network traffic between two points talked

  Hi, I have a star VPN network topology, and all traffic is remote office to the data center,

  I have a request to build a tunnel between two remote sites to access some servers between two remote sites,

  Can I just change the ACL of valuable traffic to to include say a Cabinet to Office B in rule Cabinet a Datacenter and Office B tunnel to tunnel data center.

  In doing so, I can avoide the tunnel between two offices (and B)

  See you soon

  Hello

  You can make the traffic between the two rays go through the hub or build a new tunnel between the rays.

  If the hub is an ASA you must authorize same-security-traffic intra-interface permits

  If the hub and the spokes are routers, you can also use DMVPN to dynamically create a tunnel between the spokes when necessary.

• VPN Hub and Spoke with NAT

  Hello! I have a VPN network star topology, I need configuration for our customers to access. I have 3 points of endpoint in this example: VPN, Pix 515e and Linksys RV042 hub. The hub is the site of our parent company, the Pix 515e is our data center and the RV042 is at the customer's site. What I currently have is a VPN connection between our Pix 515e and the hub, and another between our Pix 515e and the RV042 VPN. What I need is for the server on the client (RV042) site to talk to the hub network via our Pix 515e. I also need to be coordinated traffic so it looks like it's from the same subnet on our Pix 515e to the hub.

  Hub (MEAN): 10.1.6.x

  PIX 515e (HUB): 172.16.3.x

  RV042 (SPOKEN): 192.168.71.x

  PIX 515e (HUB):

  Outside - 12.34.56.78

  Interior - 172.16.1.1

  Hub (TALK):

  Outside - 87.65.43.21

  Interior - 10.1.6.1

  RV042 (SPOKEN):

  Outside - 150.150.150.150

  Interior - 192.168.71.1

  The hub allows all traffic to my Pix 515e on subnet 172.16.3.x and vice versa. The RV042 allows all traffic from 172.16.3.x to talk to 192.168.71.x and vice versa. I need to get 192.168.71.5 on RV042 network 10.1.6.x the network hub through the Pix 515e and make it look like its 172.16.3.71 entry. So I need NAT traffic in the tunnel to another tunnel. Attached config running under the direction of privacy. Any help is greatly appreciated.

  On PIX you need a static policy statement,

  NAT list allowed access host ip 192.168.71.5 10.1.6.0 255.255.255.0

  public static 172.16.3.71 (external, outside) 192.168.71.5 nat access list

  And modify the ACL of appropriately crypto to include natted address.

• 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.

  client configuration address map clientmap crypto answer

  AND change the following items on your profile isakmp:

  ISAKMP authorization list groupauthor

  Also if you'll use a list for user authentication, I advise you to avoid using the default list so go ahead and change it too much under the isakmp profile

• 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.

• VPN ipsec and port 500

  Hello world

  I connected connection VPN IPSEC.

  Connection works fine.

  Here's the Setup program

  PC---R1---R2--R3---ISP---ASA

  I check on R3

  The R3 CBAC is configured.

  R3 # sh ip inspect sessions | 96.51.x.x Inc.
  65719DB4 (192.168.98.6:59936)-online (96.51.x.x:4500) SIS_OPEN udp session

  What vpn ipsec connection is established, it shows that it is plugged into the port 4500 not 500?

  What is default behavior?

  Initially when he formed theVPN connection it showed both udp, ports 500 and 4500.

  Concerning

  MAhesh

  It has NAT/PAT between R3 and ASA. like address (192.168.98.6) private IP allows you to configure the ipsec session.  IKE detects NAT/PAT exist in NAT - D payload. IKE uses UDP 4500 to negotiate ISAKMP rather than UDP 500. Subsequently, the ESP traffic is also encapsulated in UDP 4500, in this way it can cross the NAT/PAT safely.

  If this behavior is expected.

  Duyen

  Hello Duyen,

  I think I've narrowed the issue. When remote access VPN using RADIUS authentication we must keep in mind that authentication and authorization are included on the same package.

  Depending on your configuration, the ACS is defined as a server RADIUS (Gserver Protocol radius aaa server) and becomes the VPN Tunnel authenticated and 'authorized' on this server group:

  authentication-server-group LOCAL Gserver

  authorization-server-group Gserver

  As noted above, the RADIUS of request/response includes authentication and authorization on the same package. This seems to be a problem of incorrect configuration that we should not set up the 'permission' in the Tunnel of the group.

  Please remove the authorization under the Tunnel of Group:

  No authorization-server-group Gserver

  Please test the connection again and check the logs of the ACS. At this point there are only sucessful newspaper reported on the side of the ACS.

  Is 'Permission-server-group' LDAP permission when authenticating to a LDAP server so to retrieve the attributes of permission on the server. RAY doesn't have the command as explained above.

  I hope this helps.

  Kind regards.

• ASA Vpn load balancing and failover

  Hi all.

  We have two asa5520 configured as main unit and emergency in failover configuration, and everything works fine.

  Is it possible with this configuration (switch), configure the vpn load balancing/grouping?

  Thank you

  Daniele

  Hi Daniele,

  You cannot run two of them on two firewalls ASA, VPN feature load balancing or failover functionality.

  Where you need to use the two feature, you must use more than three ASA firewall, two first ASAs will work as the failover and the ASA third will work as cluster VPN for them, the following example uses four firewalls:

  ASA1 (active FO) - ASA2 (TF Standby)

  (VPN virtual master)

• Cisco ASA Site to Site VPN IPSEC and NAT question

  Hi people,

  I have a question about the two Site to Site VPN IPSEC and NAT. basically what I want to achieve is to do the following:

  ASA2 is at HQ and ASA1 is a remote site. I have no problem setting a static static is a Site to IPSEC VPN between sites. Guests residing in 10.1.0.0/16 are able to communicate with hosts in 192.168.1.0/24, but what I want is to configure the NAT with IPSEC VPN for this host to 10.1.0.0/16 will communicate with hosts in 192.168.1.0/24 with translated addresses

  Just an example:

  N2 host (10.1.0.1/16) contacted N1 192.168.1.5 with destination host say 10.23.1.5 No 192.168.1.5 (notice the last byte is the same in the present case,.5)

  The translation still for the rest of the communication (host pings ip destination host 10.23.1.6 N3 N2 not 192.168.1.6 new last byte is the same)

  It sounds a bit confusing to me, but I've seen this type of configuration before when I worked for the supplier of managed services where we have given our customers (Ipsec Site to Site VPN with NAT, don't know how it was setup)

  Basically we contact the customer via site-to-site VPN hosts but their real address were hidden and we used as translated address more high 10.23.1.0/24 instead of (real) 192.168.1.0/24, last byte must be the same.

  Grateful if someone can shed some light on this subject.

  Hello

  OK so went with the old format of NAT configuration

  It seems to me that you could do the following:

  • Configure the ASA1 with static NAT strategy
    • access-list L2LVPN-POLICYNAT allowed ip 192.168.1.0 255.255.255.0 10.1.0.0 255.255.0.0
    • public static 10.23.1.0 (inside, outside) access-list L2LVPN-POLICYNAT
  • Because the above is a static NAT of the policy, this means that the translation will be made only when the destination network is 10.1.0.0/16
  • If you have for example a PAT basic configuration to inside-> external traffic, the above NAT configuration and the custom of the actual configuration of PAT interfere with eachother
  • ASA2 side, you can normally configure NAT0 / NAT Exemption for the 10.1.0.0/16 network
    • Note of the INTERIOR-SHEEP access-list SHEEP L2LVPN
    • the permitted INSIDE SHEEP 10.1.0.0 ip access list 255.255.0.0 10.23.1.0 255.255.255.0
    • NAT (inside) 0-list of access to the INTERIOR-SHEEP
  • You will need to consider that your access-list defining the VPN encrypted L2L traffic must reflect the new NAT network
    • ASA1: allowed to access-list L2LVPN-ENCRYPTIONDOMAIN ip 10.23.1.0 255.255.255.0 10.1.0.0 255.255.0.0
    • ASA2: list L2LVPN-ENCRYPTIONDOMAIN allowed ip 10.1.0.0 access 255.255.0.0 10.23.1.0 255.255.255.0

  I could test this configuration to work tomorrow but I would like to know if it works.

  Please rate if this was helpful
