• Dynamic routing for VPN Failover L2L

  Hello

  Can someone offer me some advice on this please?

  I have attached a simple diagram of our EXTENSIVE referral network.

  Overview

  • The firewall is ASA 5510 running 8.4 (9)
  • Basic to the Headquarters network uses OSPF
  • On ASA static routes are redistributed into OSPF
  • On ASA for VPN static routes are redistributed into OSPF with 130 metric so redistributed BGP routes are preferred
  • Basic network has a static route to 10.0.0.0/8 to Corporate WAN, which is redistributed into OSPF
  • Branch Office WAN uses BGP - routes are redistributed into OSPF
  • The branch routers using VRRP for redundancy of the IP for the default gateway of local customers.
  • Branch router main past off VRRP IP to router backup when the WAN interface is down
  • BO backup router (. 253) contains only a default route to the internet
  • In normal operation, the traffic to and from BO uses Local Branch Office WAN
  • If local BO WAN link fails, traffic to and from the BO uses IPSec VPN via public Internet

  I try to configure dynamic routing on our network for when a branch switches to the IPsec VPN. What I want to happen (not sure if it is possible) is for the ASA announce the subnet to the remote end of the VPN in OSPF to Headquarters.

  I managed to get this working using IPP, but for some reason any VPN stay up all the time when we are not in a failover scenario. This causes the ASA added the table as a static route is the remote subnet in it and do not use the announced route of OSPF from the core network. This prevents the BO customers access to the Internet. If I remove the IPP on the VPN setting, ASA learns the route to the subnet via the WAN BO - resumes normal operation.

  I have configured the metric of the static routes that get redistributed into OSPF by ASA superior to 110. This is so that the routes redistributed by the WAN BO OSPF BGP, are preferred. The idea being that when the WAN link is again available, the routing changes automatically and the site fails to WAN BO.

  I guess what I need to know is; This design is feasible, and if so where I'm going wrong?

  Thank you

  Hi Paul,.

  your ASA maintains the tunnel alive only because this path exists on ASA.  This is why you must use IP - SLA on ASA to push network taffic "10.10.10.0/24" based on the echo response, using the ALS-intellectual property

  Please look at the example below, in the example below shows that the traffic flows through the tunnel, only if the ASA cannot reach the 10.10.10.0/24 network via the internal network of HQ.

  This configuration illuminate ASA.

  Route inside 10.10.10.0 255.255.2550 10.0.0.2 track 10

  (assuming 10.0.0.2 ip peering from inside the ip address of the router to HO)

  Route outside 10.10.10.0 255.255.255.0 xxx.xxx.xxx.xxx 254

  (value of 254 is a more expensive route to go via IPSec tunnel and x = the bridge by default-ISP)

  ALS 99 monitor

  type echo protocol ipIcmpEcho 10.10.10.254 inside interface

  NUM-package of 3

  frequency 10

  Annex monitor SLA 99 life never start-time now

  track 10 rtr 99 accessibility

  Let me know, if this can help.

• Cisco IOS SSL VPN on mobile

  Hello

  I want to know can I use the Cisco IOS SSL VPN on the use of mobile client Anyconnect. If yes what is the prerequisite, is there any kind of additional license required.

  Thank you

  In the following article:

  http://www.Cisco.com/c/en/us/support/docs/security/AnyConnect-VPN-client...

  Q. is possible to connect the iPad, iPod or iPhone AnyConnect VPN Client to a Cisco IOS router?

  A. No. it is not possible to connect the iPad, iPod or iPhone AnyConnect VPN Client to a Cisco IOS router. AnyConnect on iPad/iPhone can connect only to an ASA that is running version 3,0000.1 or a later version. Cisco IOS is not supported by the AnyConnect VPN Client for Apple iOS. For more information, refer to the section security devices and software support to the Release Notes for Cisco AnyConnect Secure Mobility Client 2.4, Apple iOS 4.2 and 4.3.

  Hello

  The unit behind your ASAs on the internal LAN should really be a router switch or L3 and not a basic L2 switch.

  You now have an asymmetric routing on your network, and this is the reason why the connection of the VPN device will not work.

  The problem comes from the fact that internal devices use the ASA1 for the default gateway. When trying to connect to the VPN Client, the following happens

  • Client VPN armed sends TCP SYN that happens by the VPN with the ASA2
  • ASA2 passes the TCP SYN to the server
  • Server responds with TCP SYN ACK for the VPN Client and sends this information to the ASA1 as the destination host is in another network (vpn pool)
  • ASA1 sees the TCP SYN ACK, but never saw the TCP SYN so he abandoned the connection.

  To work around the problem, you need to essentially configure TCP State Bypass on the ASA1 although I wouldn't really say that, but rather to change the configuration of the network so that traffic makes this way to start.

  An option, even if not the best, would be to set the LAN of the ASA2 to ASA1 on some physical ports and set up a new network connection between them (not the same 192.168.10.x/yy). In this way the ASA1 would see the entire conversation between servers and VPN Clients and there are no problems with the flow of traffic.

  But as I said it probably still isn't the best solution, but in my opinion better than having recourse to special configurations ASA1.

  There could be a 'special' configuration on the ASA2 that you could use to make the Client VPN connections operate in their current configuration, without changing anything in the physical topology.

  You can change the NAT for VPN Clients configuration so that the VPN ALL users would actually PATed to 192.168.10.4 IP address when they connect to your internal network. Given that the server would see the connection coming from the same network segment, they would know to forward traffic back with the ASA2 rather than ASA1 like her today.

  If this is not an ideal solution.

  No source (indoor, outdoor) nat static any any static destination NETWORK_OBJ_10.0.0.0 NETWORK_OBJ_10.0.0.0 non-proxy-arp-search to itinerary

  the object of the LAN network

  192.168.10.0 subnet 255.255.255.0

• How to check if the remote VPN failover is configured

  Hello world

  We have two sites and have both remote access VPN configured.

  IF a VPN site fails users automatically fail over to another site.

  Need to know what that orders can I run on ASA to check if remote VPN failover is there?

  Also what lines by running config shhould I seek?

  Thank you

  Mahesh

  Based on your configuration, it can vary, below link has someVPN failover configurations, you can find a few commands to check redundancy on your network:

  http://www.Cisco.com/en/us/docs/iOS/12_2/12_2y/12_2yx11/feature/guide/ft_vpnha.html#wp1093554

  What you should look at your config running is also based on your configuration, it should be something like: main, standby or emergency.

• Site to site VPN (ASA-> router IOS, with two interfaces) help

  Dear,

  I need help to configure VPN from Site to Site of cisco ASA to the IOS router, the router has 2 WAN links, a primary and secondary backup.

  There was only a single week of link there is, now we have installed the second link as a backup, we use OSPF as the routing protocol.

  VPN with simple link worked fine, now, when the main link fails the network is down.

  Waiting for response.

  There is an easy solution.  On the router, you must terminate the VPN on the loopback interface.

  something like this:

  interface lo0

  IP x.x.x.x where x.x.x.x

  card crypto-address lo0

  interface wan_1

  vpn crypto card

  interface wan_2

  vpn crypto card

  One condition is that the loopback interface has accessible by the device of the SAA.

• Cisco and Checkpoint VPN clients on a single PC

  Hello

  I'm in the following fix:

  I had used customer Checkpoint SecuRemote 4.1 SP - 5 VPN in the past.

  Now, I have installed the Cisco VPN client version 4.0.4 on my PC to access IPSec VPN for the PIX in our headquarters.

  According to Cisco VPN release notes http://www.cisco.com/univercd/cc/td/doc/product/vpn/client/rel404/404clnt.htm#wp1346340 , it should be possible to have clients both Cisco and Checkpoint VPN installed on the same machine.

  But I am not able to connect to my PIX, I receive the following error message:

  "Secure the complete VPN connection locally by the Client.

  Reason 403: failed to contact the security gateway. »

  When I'm looking for signs of PC control-> system-> hardware-> device Administration-> network cards, I can see Cisco Systems VPN Adapter disabled.

  After you activate manually, I always get the same error when you try to connect to the Cisco VPN client.

  After PC restart the Cisco VPN adapter is disabled later.

  I tried to uncheck Check Point SecuRemote form my Dial-up connection (bypassing CSCea31192 of bug, but the bug does not affect NAT - T connection which I use).

  I noticed the same situation on three different computers, one running Windows XP, both running Windows 2000.

  After uninstalling the client Checkpoint completely (including Windows registry manual removal), the Cisco VPN client works very well.

  It seems to me, therefore, that there is a profound mismatch between Cisco and Checkpoint VPN clients.

  Does anyone know of a workaround?

  Thank you

  Milan

  We had the same problem with some of our users who need to use the two clients to connect to customer sites.

  If I remember the cisco client does not start automatically, but the client of checkpoint 4.1 don't.

  We by-passed by deleting the registry entry point control that starts the client at startup. fwenc.exe is the entrance and it is in

  HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

  After that make a shortcut to the executable file that is stored in the directory \bin to relevant checkpoint on the client (it is different from NT & 9 client x) and then only start when it is necessary.

  Hope that's a help

• PIX VPN failover to different data centers

  Hello

  I got 90 sites with PIX 501 6.4 (4) that connect to a centralized with pre-shared key and ip data center site.

  We seek to set up another site and provide a VPN failover service.

  Disaster, we would like the 501 to start to use the new Concentrator VPN sites.

  I had a glance on the configuration guide and it doesn't look like we could use DNS for the exchange of traffic.

  Is there some I could get the 501 to use the second VPN Service if the primary data center is taken out.

  It will work. It will use the second pair if the first is not available. I think this is mentioned in the guide configuration somewhere, but I'll have to look. Please rate if this can help.

  Hello Manjitriat,

  Okay, detected IPSEC parody is normal, that means you are trying to send unencrypted on a line of encrypted packets.

  Now, if you see on the plotter of package that traffic will hollow the VPN channel all its fine in your site.

  Now the packet tracer must be something like this:

  Please provide us with the result of the following instructions after you run the packet tracer.

• Cisco router VPN Failover-

  Hello Experts,

  I have a very simple setup.  I have a Cisco 1841 router with 3 interfaces.  (1eth for LAN, 1eth to ISP2 and 1 eth for isps1).

  I managed to create backup of VPN tunnel using course maps.

  Now, I have to create a failover of VPN with a separate router.  What is the best way to do it?  Examples of configuration would be great.

  This is my setup:

  LAN - firewall-fire-(internal) router (isps1) = Tunnel VPN = VPN - Endpoint1

  |

  |

  |

  (Inside) Router (ISP2) = tunnels2 VPN = Endpoint2 VPN

  So, the trick would be 2 VPN sites on 2 different routers configuration.

  Thank you

  Randall

  Hi randall,.

  Simple. Configure HSRP between 2 routers and create the same configuration on the 2nd router as well. Since the tunnel establish when there is always some interesteing traffic a router will be preferred. Simply connect two routers a switch and the inside interface in the same subnet.

  Here is the link that I could help you

• Cisco IOS IPSec failover | Route based VPN with HSRP

  I can find the redundancy of vpn IPSec using policy based VPN with HSRP.

  Any document which ensures redundancy of the road-base-vpn with HSRP?

  OK, I now understand the question. Sorry, I have no documents for this task.

  I can see in the crypto ipsec profile that you will use under the Tunnel interface configuration to enable the protection, you can configure the redundancy:

  cisco(config)#crypto ipsec profile VTIcisco(ipsec-profile)#?Crypto Map configuration commands: default Set a command to its defaults description Description of the crypto map statement policy dialer Dialer related commands exit Exit from crypto map configuration mode no Negate a command or set its defaults redundancy Configure HA for this ipsec profile responder-only Do not initiate SAs from this device set Set values for encryption/decryption

  cisco(ipsec-profile)#redundancy MRT ? stateful enable stateful failover

  I suggest that it is the same as redundancy card crypto. But no documentation or examples found...
