• 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.

  Concerning

  John

  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.

• 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:

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

• [SRP527w] Recovery and VPN failover

  Hello

  Our company is using DSL routers to connect remote sites to our headquarters.
  We buid VPN through ADSL, between a Zyxel USG 200 Firewall/VPN device and remote routers.

  We decided to add a 3G backup connection, and we chose to test the SRP527w for this purpose.
  Thanks to Andrew Hickman, who answered my questions, we build successfully an IPSEC VPN via the 3 G connection, and it works really well.

  There is a problem with the failover/recovery of the VPN tunnel:

  1)
  We start the router
  The SRP527w set up ADSL and build the VPN.
  Fails to ADSL (we remove the power cord)
  3 G starts very fast, and the WAN connection is OK (our vpn device if the internet ping)

  But the VPN tunnel never comes back!

  If I manually, click on 'Connect' menu VPN, it connect any!
  If I look at the newspaper on my VPN device, I don't see any attempt to build the VPN.
  If I re - connect ADSL, VPN connects again ADSL!

  2)
  WITH EXACTLY THE SAME SETUP AND THE SAME CONFIGURATION OF VPN ON BOTH SIDES:
  We start the router with ADSL cable disconnected.
  The SRP527w set up the 3G and build the VPN!
  We re - connect the ADSL and ADSL connects with success (our vpn Internet device ping)

  But the VPN tunnel never comes back!

  If I manually, click on 'Connect' menu VPN, it connect any!
  If I look at the newspaper on my VPN device, I don't see any attempt to build the VPN.
  If I unplug the ADSL, the VPN will connect again through 3 G!

  My configuration:

  Failover and restore enabled, with delay set to 60 sec.
  ADSL first, then 3 g 1 PVC enabled on ADSL.
  1 IPSEC policy and 1 IKE policy, two correspondents with 1 tunnel on my VPN device (configured in "Dynamic Peer" because there is no static IP address on the 3G connection).

  Version ID: V01
  Hardware version: 4.0.0
  Version of the boot: 1.1.17
  Firmware version: 1.01.19

  It's as if once the VPN is configured on the first WAN interface, it cannot be setup on the second if the first fails. Andrew, are you familiar with this issue? I'm doing it wrong somewhere?

  Thank you very much for your answer.

• 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

  Paul

  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

• ASA 5500 SSL VPN Failover license

  Hello

  I have a partner who request assistance with SSL VPN licenses on the ASA 5500 firewall sharing:

  His question is:

  Both SSL, provided with the firewall of the SAA, licenses can be shared across a couple active / standby?  I would therefore have a total of (4) licenses of SSL VPN to use?

  This would also be true for two security contexts that are included with the firewall?

  For example, I buy two base ASA 5520 firewall, running active / standby, that each machine is supplied with SSL VPN licenses (2) and (2) licensing of security contexts? In version 8.3, the licenses are cumulative by failover pairs, so I should a total SSL VPN (4) and (4) security contexts?

  Here is my response to his request:

  Based on this link (http://www.cisco.com/en/US/partner/docs/security/asa/asa83/license_standalone/license_management/license.html#wp1449664)

  It was mentioned that:

  "You can have one active license type, either the AnyConnect Essentials license or the AnyConnect Premium license. By default, the Adaptive security apparatus includes an AnyConnect Premium license for 2 sessions. If you install the AnyConnect Essentials license, it is used by default. See not anyconnect-essentials control or in ASDM Configuration > remote access VPN > network (Client) access > advanced > component AnyConnect Essentials to activate the Premium license instead. »

  It will be able to share the included license on the ASA 5500 4. It will be able to share these licenses, but I'm not sure the security context. My answer would be, it can use only 2 context Security licenses since only the VPN licenses are shared on the version 8.3 and other licenses not characteristic. My understanding is correct? or there are other explanations on my customer survey?

  Thanks in advance!

  Cisco partner Helpline Tier 2 team

  Only from ASA 8.3 version and following, the license can be combined on a failover pair active / standby.

  2 SSL included license on SAA in failover pair is combined as 4 license SSL.

  2 license of background on ASA in failover pair is combined as license frame 4.

• IPSec VPN with private WAN address... Help!

  I am trying to establish an IPSec Site to Site VPN to my company network. I use a Cisco 2811. If I plug a Public IP WAN connection my tunnel past traffic without problem, but if I tell a router in the middle where the 2811 pulls a private IP address of the home router I no longer get a tunnel a success. Any suggestion?

  I have the following instructions.

  FA 0/0
  DHCP IP ADDRESS
  CRYPTO MAP AESMAP

  VLAN 1
  IP ADDRESS XX. XX. XX. XX 255.255.255.240 (public IP)

  IP ROUTE 0.0.0.0 0.0.0.0 FA 0/0

  If this can help clerify the "router" is a CradlePoint (CRT500) that takes the Mobile 3 G and send it to an ethernet port on the WAN port on my router. The installation remains mobile and I rarely get the chance to have a public IP address for my WAN. Currently I use a SonicWall TX 100 router that allows me to VPN to my network of companies. We hope to move all of our mobile kits to the cisco product, but need to find a solution before change can occur.

  If I do 'Show IP Crypto ISAKMP SA' it shows: XX. XX. XX. XX (PUBLIC) <> Active 192.168.0.1.

  My thoughts are that my TCP 500 traffic to the VPN router and when the VPN router sends traffic to the address there SA with it's no the case because it is an ip address private. Limited my knowledge of the works of the VPN, I think only in Phase 1, two addresses must "bind" and NAT cannot be used with VPN? But I keep out hope that this might be a somewhat common question and there is a procedure in place to get around, or maybe I'm just a bad configuration or IP road...

  When I disable card crypto on the FA 0/0 and add NAT to the FA 0/0 and 1 VLAN more change my IP Route to "0.0.0.0 0.0.0.0 192.168.0.1" I get non - vpn connectivity.  Also, I put the address that gets my FA 0/0 in the DMZ of the Cradlepoint.

  Thanks for any help anyone can provide!

  Brandon,

  NAT - T is designed to overcome the problems of NAT/PAT, known in the world of IPv4.

  The big problem is that if you have a public IPv4 address, you will need to run PAT. Packages ESP / AH do not have a port number so that they cannot be PATed. To do this, we enacapsulate IPsec payload inside udp/4500 packages.

  That being said, some providers overcome this problem differently, but it's not THE standard way.

  Your head should see you as PublicIP facig of internet device.

  I agree, that both sonicwall and IOS should work with other IOS. At the same time, it is difficult to say what is happening in the middle.

  I would say that if possible, connect you to a case of TAC, the guys will be able to view your configs and able to solve the problem when it's there. These types of discussions on the forums can go for very long ;-)

• SSL VPN failover

  Hello

  I have a SSL VPN 500 license running device. I also have a beam of 5520 firewall only. Can I use the firewall as a failover cluster (active / active OR active / standby) to the current 5520 with 500 licenses SSL?

  If this is not the case, what is necessary to have a failover for 5520 with 500 appliance SSL?

  Thank you

  Wine

  If you run version 8.2 and earlier, then you must have the 500 user license of SSL enabled on the new ASA5520 to perform failover.

  The two needs of ASA to have exactly the same material, the module, the license to run the failover if they perform version 8.2 and earlier versions.

  However, if you are using version 8.3 and later, there is no need to have the 500 user license of SSL enabled on the new ASA5520. You can configure failover immediately.

  Hope that answers your question.

• Cisco 890 series - VPN failover router

  Hello Experts,

  We have 2 connections ADSL 2 ISPS get into our headquarters. We also have a branch office and a virtual private network between the sites. If we install a Cisco 897VA or a 896VA of Cisco in our headquarters that can automatically failover the VPN connection if the line ADSL primary fails? If so could you tell me how it works?

  Enjoy your time

  Thank you

  Ranil

  Naty Hello,

  Yes it is possible, lets say that you configure two tunnels GRE protected with IPsec, the two tunnels will end on the router of the Headquarters on the different DSL interfaces. BO router you configure two static routes or subnet HO road via tunnel backup with higher AD so it will be used only if the main tunnel goes down and then with drop AD emptied out of the routing table.

• VPN failover between the ASA

  I do a search in the search of the best solution for switching between two ASA and hoped that someone wants to point me in the right direction.

  The situation is this, we got:

  -Head Office 2:

  Each is equipped with an ASA 5505

  -10 branches

  Each is equipped with a 887 integrated services router.

  Each is BranchOffice must have a redundant VPN connection at the headquarters of these two, and they all need to use the first person as main and the other in high school. In case of failure, all branches need to use the second connection VPN going the second seat.

  In my research, I'm looking for the best possible solution, with faster failover, but have no idea where to start my research.

  I hope someone has a good answer for this one.

  Thank you very much in advance,

  Kind regards

  Dwayne

  I do not understand why people continue to use ASA devices for VPN endpoint.  the ASA is NOT designed for complex VPN scenarios.  It is designed for simple scenarios.  In terms of VPN by using comparison, ASA is a person with a basic education while Cisco IOS is like a person with a college degree.

  For the scenario, you will be much better using Cisco IOS routers everywhere, where you can implement the GRE/IPSec or DMVPN.  Both cases will be sastify to your needs.

• S2S VPN Failover

  In the case where we have 2 routers each with a WAN link provided by the only ISP we can configure HSRP with SSO for the classical solutions IPSEC failover. But in a case where there are 2 routers but differ from the WAN links (services provider) we will not be able to use HSRP because the IP (subnet) will be different and assign a virtual ip address that is impossible.

  In this case, this type of the best possible solution for the recovery of link to function? ASIT with cryptographic cards? because in this case we can do 2 tunnels each with different source and IPSLA or dynamic routing routes of change for a failover.

  If you want to route based on the source IP address that some sources are going through the tunnel and not others?

  That could be solved with the policy based routing.

• 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

• Utm9s double vpn double wan

  Hello world

  is my first time that I'm dealing with a firewall, netgear, anda sicerely I'm having a problem with a configuration.

  I have 2 utm9s and was asked to me to configure mode vpn dual wan dua.

  Let me be more specific, we have 2 site with each of them with 2 connection to public broadband and ip.

  the goal is to make 2 tunnel vpn failover via the wan connection separated 2,.

  the problem is, when I set up the wizard, it says that the configuration is invalid.

  on the manual that I have seen that it is technically possible, but I don't know how...

  Thank you all

  Hello

  As far as I know, setting up two VPN IPSec connections between the same two routers is not the way forward.

  It will not work because the VPN policies will come into conflict with each other ('the destination subnet foo has to go through the VPN bar' rule must be unique).

  To set this up correctly, you must use the substitution inside politics VPN, on both sides. And because you can define only a single IP address as remote endpoint, you must use a FULL domain name.

  The reversal option determines what use of WAN interface as outgoing and remote as endpoint FULL domain name determines which remote IP address is used for communication.
