• VPN tunnel between the concentrator 3005 and router Cisco 827

  I am trying to establish a VPN tunnel between the Central Office with VPN 3005 and controller branch Cisco 827 router.

  There is a router of perimeter with access set up in front of the 3005 list.

  I quote the ACLs on the Central perimeter router instructionsuivante to allow traffic to permit ip 3005 - acl 101 all 193.188.X.X (address of the hub)

  I get the following message appears when I try to ping a local host in the Central site.

  Can Anyoune give me the correct steps to 827 and 3005.

  Thank you

• Two VPN tunnels on the same device with the same protected networks

  There is a remote site that wants me to put in place two separate tunnels of VPN with the same internal IP at each end. FOR EXAMPLE

  LAN = 10.212.170.201/32, 10.212.170.202/32

  Remote network 192.168.0.0/24 =

  I currently have a tunnel between the above:

  End Point distance = 111.93.152.186

  Local endpoint point = 198.205.115.252

  Now, they want to set up a VPN for the same networks between:

  End Point distance = 115.115.130.34

  Local endpoint point = 198.205.115.252

  It is my understanding that the Cisco ASA 5520 can do. The only way I've seen this done with Cisco hardware is to use two ASAs, but there may be a way to use the costs of road or some other tricks to make it happen.

  I'm open to suggestions.

  Is a backup?

  In, specify endpoint remote second as a "backup" of the peer in the first virtual private network.  Alone will be active at the time - but there are toggled if the VPN in first dies.

• VPN Tunnel to the TOP but no traffic passing (PIX515)

  I'll put up a remote engineers access to off-site to access my network (using the cisco vpn client). I use PIX 515E software version 7.0 (3) 20 as a vpn server. I can establish a tunnel, but I can't access network resources. I can ping the external interface of the PIX. This is my setup: internet-router-pix-dmz(server farm). Please find attached my setup. Thanks in advance.

  After a glance at your policy, it seems that the Pool of IP, that is assigned to the clients behind the outside interface, runs behind the DMZ. I don't think it will work.

  In addition, defined distribution policy seems to be backward. Im sure that you intend to send traffic FROM the IP pool to 196.26.12.64/26. Your acl split is the opposite.

  In addition, your routing table does not contain a route for the 196 network, so the firewall will use the default route to the outside. If this is intentional, the clients and dst are on the outside, which is considered to be crossed. This is allowed on the SAA only with the same security setting configured.

• Is it possible to build a vpn tunnel to the DMZ on a pix 515 interface?

  I would like to know if it is possible to have a vpn tunnel ending on a DMZ interface rather then inside interface of a pix 3-way. All the examples of configuration, I found route traffic from the VPN client somewhere on the internet on the inside interface of the pix. I tried a sheep-access list of the demilitarized zone to the vpn client, but it does not work. According to me, because the vpn traffic goes to the safety higher by definition interface. Am I wrong?

• Problems with VPN tunnels after the upgrade to PIX 7.0

  It seems that Cisco has revamped the VPN process on the new Version of PIX 7.0.

  After I've upgraded, I noticed that AH (i.e. ah-sha-hmac, ah-md5-hmac) was no longer supported and all my container transformation games OH no were not converted.

  Another question, if you have enabled on Versieon 6.3, names when you upgrade, tunnel groups will be created (formerly "identity isakmp crypto, crypto key isakmp peer ') which will include a hostname (hostname of identity) instead of IP as it was to the point 6.3. Guess what... Nothing works! Having to delete and recreate it using the IP address.

  See an example...

  tunnel-group OTHER_END type ipsec-l2l

  IPSec-attributes tunnel-group OTHER_END

  pre-shared-key *.

  The above does not work... Having to recreate using the IP address mapped to OTHER_END...

  tunnel-group 2.2.2.2 type ipsec-l2l

  2.2.2.2 tunnel-group ipsec-attributes

  pre-shared-key *.

  Furthermore, I have problems with my racoon and freeswan extranet... Did someone recently updated with success and other gateways VPN provider (i.e. checkpoint, Freeswan and Racoon) work?

  We found the solution for this problem. It appeared that the perfect forward secrecy is enabled at the other side. If a 'card crypto outside_map 10 set pfs' is necessary. With the pix 6.3 version that appears not to make the difference, the vpn works even with pfs disabled on the side of pix.

• SSL VPN authentication using the ad group

  Hi all

  I tried to restrict users to authenticate to the SSL VPN using an ad server. I have install the AAA server with the IP address of the AD server and attributed to the connection profile as well; However, I see that any user who is a member of a group in AD is able to authenticate.

  I want to only users who belong to the group "VPN users" get authenticated while everyone and all those who have credentials of the AD and not even a part of the 'VPN users' group is making authenticated.

  Can someone advice how I can make the ASA authenticate users based on ad groups? I use the ASDM to configure my VPN RA.

  Thanks in advance!

  Kind regards

  Hey riri,.

  Try to use DAP to restrict access to users who belong to a specific ad group:

  Use the AAA attribute "LDAP .member of" to allow access to the users belonging to a specific group and deny access to other users.

• How to get to the VPN tunnel to the subnet 2/3

  I have not yet tried something else a few years back I got on my back which head with an ASA firewall you cannot route traffic to a subnet of second or third (it's 2 or 3 jumps away) on a same VPN tunnel if you add routes to all LAN subnets in all required firewall and tunnels.

  I know other manufacturers such as SonicWall, here you can do it, so the question is, is possible in the firewall Cisco ASA with version 7.07 and 7.2.4? If this is not the case, is it possible in a future release? and if this is not possible, how can I make it work? I can't work with a firewall router 1 LAN to LAN s 3?

  Attached are also a network card for the visualization of all subnets.

  Thanks in advance

  If the firewall HQ is already connected to LAN2 (way I mean), then you have even connect an interface on the firewall of HQ and in him giving an ip address that belongs to LAN2. As firewall HQ has a route to 192.168.20.0/24 and 18.0/24 and vice versa, that's enough.

  And you're on the point on the rest of the steps you have provided regarding the config.

  And of course, you must configure matching exemption to ACL and NAT image mirror on the remote VPN encryption too.

• Backup of the GRE Tunnel using the address IP of Seconadary

  Is it possible to configure a GRE Tunnel to backup using an IP of Seconadary address on the WAN interface.  The router is a

  Cisco 871.  Any help would be greatly appreciated.

  Thank you.

  Nicholas

  I'm not sure it would work for use a secondary address on the WAN interface for a GRE tunnel. Maybe if you tell us more about what you're trying to do we could be able to help find alternatives that would work.

  Two tunnels from the same interface (even though you could use a secondary address) to another router would not provide a backup, if they work at all. Work of two tunnels of the same interface of router (and two using the main address) fairly well if they go to different remote routers, and it is a common way to provide backup for the GRE tunnels.

• Authentication IPsec VPN Client using the digital certificate

  Hello

  Please I need some clarification and help to set up my ASA 5540 with IOS 8.3 x for client certificate authentication remote.

  I have my certificate root from the Microsoft CA, but not quite sure if the steps described in the following cisco Web sites are exactly what I need since the firewall seems to generate the certificate to use.

  http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a0080930f21.shtml

  http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a008073b12b.shtml

  My setup is such that the CA will issue certificates to remote clients and the ASA firewall, and remote clients will authenticate and connect with their certificates which the firewall is constantly updating using the Revocation list updated by the certification authority.

  The dhcp pool must be issued by the DC inside network and not on the firewall.

  Are there any examples or best practices to achieve steps will be really appreciated.

  Thank you

  Hi Josh,.

  Let me explain briefly how Auth PKI:

  In a public key infrastructure configuration, devices trust not each other directly, but they have a certification authority, which is the one who issues the certificate. We call this root CA (there may be a more complex configuration WHERE intermediate are involved, but that's another story). So when the root CA issues a certificate, he signs it with its private key. To be able to verify this signature, we should have the CA public key, which is included with the certification authority.

  So for certificate authentication, you must create a trustpoint, that defines the parameters of the root certification authority.

  Then you will authenticate this trustpoint, which basically means that you will get the certificate of the root CA and store locally.

  After that, you sign up to this CA, which means that you will ask for (and get) your own certificate.

  Other users will do the same and have the same root CA Cert, but different personal (identity) certificates.

  So what happens on authentication is that both ends send their certificate to the other, and they will use the public key contained in the root CA to validate the signature of the certificate received from the remote peer. If the signature is correct, this means that the certificate authority root actually issued the certificate, and this remote peer can be trusted (or not)

  Hope this is clear.

• GRE and IPSEC VPN tunnel over the same interface

  My client is currently connected to a service provider of call through a GRE Tunnel over IPSEC. They chose to move all connections to a VPN site-to-site traditional behind a firewall, here, to your corp office.  As the questions says, is possible for me to put in place the VPN site to site on the same router? Interface Tunnelx both ethernet have the same encryption card assigned to the destination router.  I thought that traffic could divide by identification of traffic 'interesting '.  Thanks for all the ideas, suggestions

  Thanks for the additional information. It takes so that the existing entries in ACL 101 remain so the existing tunnel will still work. And you have to add entries that will allow the new tunnel. Editing an ACL that is actively filtering traffic can get complicated. Here is a technique that I use sometimes.

  -create a new access list (perhaps ACL 102 assuming that 102 is not already in use).

  -Copy the entries of ACL 101 to 102 and add additional entries you need in places appropriate in the ACL.

  -Once the new version of the ACL is complete in the config, then go tho the interface and change the ip access-group to point to the new ACL.

  This provides a transition that does not affect traffic. And he made it back to the original easy - especially if something does not work as expected in the new ACL.

  If the encryption of the remote card has an entry for GRE and a separate entrance for the IPSec which is a good thing and should work. I guess card crypto for GRE entry specifies an access list that allows the GRE traffic and for IPSec crypto map entry points to a different access list that identifies the IP traffic is encrypted through the IPSec tunnel.

• VPN client using the certificate self-signed on SAA

  Hello

  I need set up a vpn client that use a certificate automatically generated by the ASA.

  The VPN configuration is easy, especially with the use of the wizard.

  The problem is that I need the procedure to configure the ASA as a CA server and how to send the certificate to the client

  Thank you

  Just to let you know, the ASA can act as a CA server for authentication of cert based for ipsec vpn. It is only possible for sslvpn. So in your case, the client should be the AnyConnect client.
