• SA520w routing through site-to-site VPN tunnels

  I have several offices that are connected using site-to-site VPN tunnels and all will use the SA520W (firmware 2.1.18). I currently have 3 routers in place, router tunnels created for the router B and c of router. I need assistance with the configuration to allow the guests to router site B get to the router site C. I have attempted to add a static route, but get a destination unreachable host trying to ping. Also, if I connect to the router site has via the Cisco VPN client, I'm not able to get resources on each site, B, or C.

  A - the site 10.10.0.0/24

  Site B - 10.0.0.0/24

  Site of the C - 10.25.0.0/24

  Any help is greatly appreciated.

  So, that's what you have configured correctly?

  RTR_A

  ||

  _____________ || ___________

  ||                                            ||

  RTR_B                                RTR_C

  Since there is no tunnel between B and C there is no way for us past that traffic through RTR_A for two reasons. The most important reason is that subnet 10.25.0.0/24 (rtr_c) is not allowed to pass through the IPSec tunnel (it's okay to IPSec?) of rtr_a ==> rtr_b. You can't just add a statement of road because your addresses are not routable which is the reason why it fails.

  Your only option is to create another tunnel between rtr_b and rtr_c. This may not be the ONLY option, but you should get what you need.

  I hope this helps.

• Using the same set processing on several site to site VPN tunnels

  Hi all. I have a rather strange situation about site-to-site VPN tunnel.

  On the one hand, I have a PIX 501 and on the other end an ASA5505 and a tunnel set up between them.

  The problem is that on the side of the PIX, I can't establish a tunnel, but when the traffic starts on the side of the ASA the tunnel established as usual.

  I checked the configurations on both ends and keys, passwords, mirror that LCD seems OK. The only thing that comes to my attention, it's that I have the same set of transformation used for 2 different tunnel on the side of PIX.

  Can I use the same set of transformation on several tunnels or should I set a different transformation for each tunnel? Could be the source of the problem?

  Use it on PIX

  card crypto set pfs group2

  Or on ASA, use:

  card crypto set pfs Group1

• Site to Site VPN tunnel is not come between 2 routers

  Dear all,

  I have 2 routers for branch which is configured for VPN site-to-site, but the tunnel does not come!

  I ran debug and I enclose herwith output for your kind review and recommendation. I also enclose here the 2 routers configs branch.

  Any idea on why the Site to site VPN is not coming?

  Kind regards

  Haitham

  You guessed it!

  Just because you have re-used the same card encryption for LAN to LAN and vpn-client traffic.

  This from the DOC CD

  No.-xauth

  (Optional) Use this keyword if the router to router IP Security (IPSec) is on the same card encryption as a virtual private network (VPN) - client - to-Cisco-IOS IPSec. This keyword prevents the router causing the peer for the information of extended authentication (Xauth) (username and password).

  Reading the Site an ASDM.  Monitoring VPN can always read all four sites are connected.  But I found that Site D and E during connection reset periodically with a few hours.

  (1) I would like to know the connection during the reset time is normal or not?

  (2) any installation or configuration can refine the site to site VPN.  Make VPN tunnel more stable?

  (3) any menthod can monitor VPN site-to-site is health or not?

  Thank you very much for your help

  A. in general, the time is set to 86400 for expiration. It can also be defined by the amount of traffic

  (B) Yes. Try turning on KeepAlive IKE

  C. check the logs is as far as I know of

• ASA 5505 and ASA 5510 Site to Site VPN Tunnel cannot be established

  Hi all experts

  We are now plan to form an IPSec VPN tunnel from site to site between ASA 5505 (ASA Version 8.4) and ASA 5510 (ASA Version 8.0) but failed, would you please show me how to establish? A reference guide?

  I got error syslog 713902 and 713903, how to fix?

  I got the following, when I type "sh crypto isakmp his."

  Type: user role: initiator

  Generate a new key: no State: MM_WAIT_MSG2

  Hugo

  Hello

  This State is reached when the policies of the phase 1 do not correspond to the two ends.

  Please confirm that you have the same settings of phase 1 on both sides with the following commands:

  See the isakmp crypto race

  See the race ikev1 crypto

  Also make sure that port UDP 500 and 4500 are open for communication between your device and the remote peer.

  Finally, make sure you have a route suitable for the remote VPN endpoint device.

  Hope that helps.

• Site to Site VPN tunnel between two ASA

  I use the Site Wizard to Site on an ASA 5520, and ASA 5505 of the ADSM. Both are using 8.4 (5). When you create configurations. You follow the wizard configurations with manual what ACL s to allow the traffic of every subnet connected to talk to each other? Or they are automatically generated in the configuration file? Have not been to school yet to understand how to create the CLI VPN tunnels and what to look for.

  Thank you

  Carlos

  Hello

  First, I would like to say that I don't personally use ASDM for the configuration.

  But you should be able to configure all the necessary elements for a connection VPN L2L base through the wizard.

  I guess that typical problems to do so could relate to the lack of configuration NAT exempt or might not choose the setting "Bypass Interface Access List" that would mean you would allow traffic from the remote site in the 'external' ACL of ASA local interface. Like all other traffic coming from behind the 'outer' interface

  If you share format CLI configurations and say what networks must be able to connect via VPN L2L then I could give the required CLI format configurations.

• Unable to pass traffic between ASA Site to Site VPN Tunnel

  Hello

  I have problems passing traffic between two ASA firewall. The VPN tunnel is up with a dynamic IP and static IP address. I have attached a diagram of the VPN connection. I'm not sure where the problem lies and what to check next. I think I have all the roads and in the access lists are needed.

  I've also attached the ASA5505 config and the ASA5510.

  This is the first time that I've set up a VPN connection any guidance would be greatly appreciated.

  Thank you

  Adam

  Hello

  Regarding your opinion of configuration Remote Site ASA that you have not added the internal networks of the Central Site VPN L2L configurations at all so the traffic does not pass through the VPN.

   access-list outside_1_cryptomap extended permit ip 10.1.1.0 255.255.255.128 10.182.226.0 255.255.*.* access-list exempt extended permit ip 10.1.1.0 255.255.255.128 10.182.226.0 255.255.*.* access-list exempt extended permit ip 10.1.1.0 255.255.255.128 10.182.0.0 255.255.*.* access-list exempt extended permit ip 10.1.1.0 255.255.255.128 192.168.170.0 255.255.*.* access-list exempt extended permit ip 10.1.1.0 255.255.255.128 192.168.172.0 255.255.*.* access-list exempt extended permit ip 10.1.1.0 255.255.255.128 140.15.0.0 255.255.*.* 

  Take a look at ACL configurations above. The 'exempt' ACL is used in configurations NAT0 and tells the ASA what traffic of exempting from NAT. "outside_1_cryptomap" ACL is used to tell the traffic between the subnets should be using the L2L VPN connection.

  So in short on the Remote Site ASA these ACLs should be identical. Make additions to the LIST of VPN L2L, then try again.

  I would also like to point out that to ensure that the Central ASAs L2L VPN ACL Site contains the same networks. The ACL on the Central Site will, of course, its internal subnets as the source and the site LAN remote destination.

  THW out of ' crypto ipsec to show his " shows you that only the SA between binding Site Central network and the Remote Site LAN was established. Others have not formed as the configuration is lacking at LEAST on the Remote Site ASA. Can also be the Central Site.

  Thank you

  Hi odelaporte2,

  Is very probably the "access management" command is not applied in the second inside, only inside primary (see the race management) which will confirm.

  This command can be applied to an interface at a time, for example, if the law is now applied to the inside, it can not be applied to the inside2 at the same time.

  It may be useful

• KeepAlive in site to site VPN tunnel

  I was asked a question by a colleague today if there is any way that a keepalive

  can be configured so that site to site tunnels would remain place, vs having to have interesting traffic to allow the ISAKMP

  negotiations occur to bring up the tunnel on the SAA.

  The configuration is of a PIX running version 6.3.3 on one end to the other end, which is a code running ASA 8.3.1.

  Is there a function which would leave the tunnel to the top?

  Thank you

• only one statement of site-to-site VPN remote network?

  Hello

  I wonder on in case of site to site vpn, we can define only a single declaration of network for the Branch Office peer network?

  If there is a local network to peer site, then, how to set those for the local subnet peer?

  Can anyone answer my question?

  Thank you.

  If I understand your question, wondering how to add a different subnet to an existing site-to-site VPN tunnel?

  If that is correct, you can add this network to the crypto ACL of the tunnel at a site.  But you have to demolish and rebuild the tunnel before it takes effect.

  Once you have added the required configuration, run the following commands to shoot down the tunnel.  Do not forget that this disconnects all users on the VPN, so it is best to let users know when you go to so that they are not connected at this time here.

• VPN - PC (vpn client) problem-> router-> (site to site vpn)-> local network

  Hello

  is it possible to install?

  I have a pc and I want to connect to the Remote LAN.

  PC (using vpn client) - vpn (internet)---> ROUTER1 - a vpn (MPLS network)---> ROUTER2---> SERVER site

  How can I connect to a remote server? Is there an easy way?

  I did the configuration of the vpn client (I can connect ROUTER1 and access a LAN via vpn with 192.168.1.x), but I can't connect to the server, even if I set the subnet (192.168.1.x) under the access list of site to site vpn (access list for traffic that must pass between ROUTER1 and ROUTER2).

  Please advise! Thanks in advance.

  Looks like I've not well explained.

  On ROUTER1

  ===================

  1 ACL VNC_acl is used to split tunnel, so you should include IP server_NET it NOT vpn IP pool.

  2 ACL najavorbel is used to set the lan lan traffic between ROUTER1 and ROUTER2, 2 you should inlcude

  IP 192.168.133.0 allow 0.0.0.255 0.0.0.255

  You must change the crypto ROUTER2 ACL of the minor or the najavorbel of the ACL

  The other way to is to the client VPN NAT IP to a local area network lan IP ROUTER1, in this way, you don't need any changes on ROUTER2. But I have to take a look at your configuration to make the suggestion.

• NAT and Site to site VPN

  Hi all

  We currently have a PIX in our local network. There is a Site to site VPN tunnel between this PIX and another network abroad.

  We have several networks in our local network.

  The VPN tunnel is on a single network: 192.50.175.0 / 24.

  and the network of the other site is:

  192.100.24.0 21

  Part of the configuration:

  inside_nat0_outbound ip 192.50.175.0 access list allow 255.255.255.0 192.100.24.0 255.255.248.0

  NAT (inside) 0-list of access inside_nat0_outbound

  As I said before, we have several networks.

  In particular, we have 192.50.160.0/24 too.

  And we would like that this network can use the VPN tunnel also.

  But the other site does not want to carry our another network in their LAN.

  They suggest we 192.50.160.0 NAT / 24 to an IP address on the 192.50.175.0 / 24, users in a network 192.50.160.0 / 24 can also use the VPN tunnel.

  Do you know if it is possible to do it with my PIX? And how?

  It's a PIX-515-DMZ, v6.3 (5).

  Any help would be appreciated!

  Thank you

  Good point. You can be good then.
