Site to Site VPN links

• question links to site 2 site VPN with authentication cert

  Currently we are accumulate tunnel site-2-site VPN with our client. Usually we use pre-shared key as authentication with other customers without any problems, but it must use authentication cert with her this time. But the question is that our CA is different from theirs. I tried a few times, but he failed. Is it someone please let me know that he must have the certificate issued by the same certification authority to create the VPN tunnel?

  Thank you very much!

  Hello

  You can read this document to get a simple example of setting up a VPN S2S using certificates on an ASA:

  http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a0080aa5be1.shtml

  Basically the sides must have the same certification authority and If there is an intermediate certificate that must be installed also. The ASA 2 will generate a CSR (certificate access code request), now then PKI will create a certificate for both parties, commonly called "certificate of identity".

  Please pass a note and mark as he corrected the post helpful!

• Troubleshooting IPSec Site to Site VPN between ASA and 1841

  Hi all

  in the past I've implemented several VPN connections between the devices of the SAA. So I thought a site link between an ASA site and 1841 would be easier... But it seems I was mistaken.

  I configured a VPN Site to Site, as it has been described in the Document ID: SDM 110198: IPsec Site to Site VPN between ASA/PIX and an example of IOS Router Configuration (I have not used SDM but CCP).

  I have run the wizards on the ASA with ASDM and the current IOS version 15.1 1841, with CCP.

  It seems to Phase 1 and 2 are coming although my ASA in ADSM reports (monitoring > VPN > VPN statistics > Sessions) a tunnel established with some of the Tx traffic but 0 Rx traffic),

  On the ASA:

  It seems that the routing on the 1841 is working properly as I can tear down the tunnel and relaunch in scathing a host on the network of 1841, but not vice versa.

  Trounleshoot VPN of the 1841 report shows a message like "the following sources are forwarded through the interface card crypto.      (172.20.2.0 1) go to "Configure-> routing" and correct the routing table.

  I have not found an error on the 1841 config so if one of the guys reading this thread has an idea I appreciate highly suspicion!

  It's the running of the 1841 configuration

  Joerg,

  ASA receives not all VPN packages because IOS does not send anything.

  Try to send packets to the 1841 LAN to LAN of the ASA and see is the "sh cry ips its" on the 1841 increments the encrypted packets (there not)

  The problem seems so on the side of the router.

  I think that is a routing problem, but you only have one default gateway (no other channels on the router).

  The ACL 100 is set to encrypt the traffic between the two subnets.

  It seems that the ACL 101 is also bypassing NAT for VPN traffic.

  Follow these steps:

  Try running traffic of LAN router inside IP (source of ping 192.168.37.x 172.20.2.254) and see if the packages are not through the translation and obtaining encrypted.

  I would also like to delete 100 ACL from the inside interface on the router because it is used for the VPN. You can create an another ACL to apply to the interface.

  Federico.

• SSL vpn site to site vpn

  I have a couple of site to site VPN working properly on an ASA 5515. Don't know what is on the other side, as I haven't seen them. I configured a SSL vpn for remote users who must be able to access resources on remote sites. I got access to the network of site without any problems and and have added the range of IP addresses for remote users to links from site to site, but I am unable to connect. Anyone who has this performance, it would be greatly appreciated if you can help.

  Hi mbluemel,

  You need to configure the remote side to allow traffic from the remote side for SSL VPN users.
  This list of documents the measures taken to achieve this: -.

  My question is

  How can I configure VPN site-to-site between branches & head office with the same internal network (192.168.150.0/24)

  Please help me with the configuration steps & explanation

  I have experience on setting up vpn site to site between branches with differnet internal network (for example: 192.168.1.0/24 and 192.168.2.0/24)

  Hello

  Im trying to configure a vpn client access to an ios router that already has a vpn site-to site running. I don't see how the two can run on the same router.

  So I guess my question is is it possible? and if anyone has therefore had a config that they can share or a useful link.

  IM using a router 800 series with 12.4 ios

  Thank you very much

  It can be done. Look at this config example that shows a router configured with a site to site VPN and client vpn - connection

  local_proxy = 0.0.0.0/0.0.0.0/0/0 (type = 4),
  remote_proxy = 206.200.22.0/255.255.255.0/0/0 (type = 4)

  -Looks like our traffic interesting PIX and the hub are not mirrors of each other, and does not. Can you please paste the PIX here cryptographic access lists, so that I can analyze the entries.

  -Also, please make sure that you have followed all the steps during the vpn configuration according to the following links:

  If your PIX is running at version 7.x and more: http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a008064a06f.shtml

  If your PIX is running version 6.3.x: http://www.cisco.com/en/US/products/hw/vpndevc/ps2284/products_configuration_example09186a00800949d2.shtml

  Once you check the config on PIX and concentrator, please provide me with the output of "sh cry isa his" and "sh cry ipsec his ' of the PIX. With this release, we can continue to troubleshoot if there is more questions.

  Let me know if this can help,

  See you soon,.

• A Site VPN PIX501 and CISCO router

  Hello Experts,

  I have an at home test lab, I set up a site to site vpn using a router Cisco PIX501 and CISCO2691, for configurations, I have just a few links on the internet, because my background on VPN configuration is not too good, for the configuration of routers, I followed this link:

  www.Firewall.CX/Cisco-Technical-Knowledgebase/Cisco-Routers/867-Cisco-ro...

  and for configuring pIX I just use the VPN Wizard of pix. All confgurations but ping failed. Hope you can help me with this, don't know what to do here (troubleshooting).

  Joint here is the configuration of my router, topology, as well as the pix configuration. Hope you can help me with this. Thanks in advance.

  Hi Mark,

  I went in the Config of the ASA

  I see that the dispensation of Nat is stil missing there

  Please add the following

  access-list allowed sheep ip 192.168.1.0 255.255.255.0 172.21.1.0 255.255.255.0

  inside NAT) 0 access-list sheep

  Then try it should work

  Thank you

• Site-to-Site VPN IPSEC falls intermittently

  Site-to-Site VPN IPSEC falls intermittently

  I am currently having a problem with a VPN from Site to Site traffic not only not intermittently. When the problem occurs, I can't Ping the remote site to the AC Site. But I can solve the problem by Pinging from HQ at the Remote Site. My network is currently configured as follows

  -------HQ------

  7.0 (4) version of pix 515 with card Ethernet 4 ports.

  Outside of the interface connected to the Broadband DSL link.

  Outside2 Interface connected to the second link DSL broadband

  -Distance-

  I have 4 Remote Sites. 2 sites connect you to each connection to wide band at HQ to spread the load to HQ

  6.3 (5) pix 501 version

  # The problem #.

  All VPN establishes successfully to the HQ Pix

  Intermittently, a remote site will report that they cannot connect to servers/services in the HQ. When I do a show crypto ipsec's and see the crypto isakmp his headquarters there is no entry for the remote site. However when I do the same on the remote site there is an entry for the HQ. With debugging on the remote site pix I try to ping from a pc to the HQ server and I get the following (see below). If I do a "ipsec Isakmp security association claire crypto ' and ' clear crypto ipsec his ' on the pix of remote site, then I can successfully ping all servers in headquarters.

  This problem seems to have taken place only when I upgraded the pix of a 501 to 515 and added another 2 remote sites and a second broadband, as described above. I'm afraid that there is a problem with software version 7 Pix. Any advice would be greatly appreciated.

• Routing multiple subnets on a site to site VPN

  What is the recommended solution to deliver several subnets on a site to site vpn? Each subnet requires its own policy or a policy can be used for one or more subnets if the remote site has several subnets? In addition, if the remote router has only two fastethernet interfaces, it'll work if one of the interfaces of subinterface configuration or router on a stick?

  If you talk about static routing, you can simply add the routes and change the ACL for encrypted as a result traffic.

  If you want to run a dynamic routing. you will then need to IPSEC VTI.  Here is the link

  http://www.Cisco.com/en/us/docs/iOS/12_3t/12_3t14/feature/guide/gtIPSctm.html#wp1063136

  and although I did not use of subinterfaces for IPSEC VTI. but according to me, it will work.

• devices to set up a site to site vpn

  I have a stupid question.  In a site to site vpn environment, can I do the installation program by using an asa5505 on one end and a router 1811 on the other end or do I need to have two asa5505 or two 1811 routers? Can another word, I mix and match devices and perform still a site to site vpn configuration or do I have to have the same features on the two end?

  You can mix and match all you want. To him my friend. Reference the link below.

• Redundancy of site to Site VPN

  Hello

  I have two ASA 5510 configured with tunnel from site to site. on both sides of the ASA 5510 I set up the links of redundancy (completed 2 ISP links) which works very well.

  Now, I need to configure site-to-site vpn for the help link.

  Please suggest me how to configure the redundancy of a site on both sites.

  Kind regards

  Ramanantsoa

  I don't know exactly the topology of your network, but it is possible to define two peers for site-to-site VPN connection. You can do this in

  toSanJose 20 ipsec-isakmp crypto map

  correspondence address card crypto 20 90 toSanJose

  toSanJose 20 set transformation-strong crypto card

  card crypto toSanJose 20 peers set 209.165.200.229 125.126.127.22

  The first pair is always given priority, in case if it is not available it failovers exchange of a second.

  It will be useful.

  Kind regards

• IPsec site to Site VPN on Wi - Fi router

  Hello!

  Can someone tell me if there is a router Netgear Wi - Fi that can form IPsec Site to Site VPN connection between 2 Wi - Fi routers via the WAN connection?

  I know that this feature exists on the Netgear firewall, but can you have the same function on any Wi - Fi router?

  See you soon!

  Michael

  I suspect that.

  Thank you very much for the reply.

  See you soon!

• Site to site VPN, I need all internet traffic to exit the site.

  I have 2 sites connected via a pair of SRX5308

  A = 192.168.1.0/24

  IP WAN = 1.1.1.1

  B = 192.168.2.0/24

  IP WAN = 2.2.2.2

  Now what I need to do, is to have all traffic from B to go to the site one even traffic destined to the internet. That is, I need internet traffic out of our network with the IP 1.1.1.1, even if it is from the network B.

  On my I have set up a route 1.1.1.1 of the ISP, then a value by default 0/0 to 192.168.1.1 it ASA knows how to get to the peer VPN is a more specific route, but sends everything above the tunnel, at the remote end which then hairpin of ASA routes internet outside its own WAN port traffic.

  I can understand though not how to so the same thing on the pair of SRX5308 they either don't raise the tunnel or internet route to the local site address B.

  Anyone have any ideas?

  I need to do this because we are logging and monitoring of internet traffic to A site via tapping from upstream to various IDS solutions and will not (cannot) reproduce this to all our remote sites.

  Thank you

  Dave.

  After some more thought and testing I came up with a workable solution to my own problem. I'll share it here in case it can help others.

  (1) use the wizard at both ends to implement a normal VPN that connects the two segments of network 192.168.1.0 and 192.168.2.0

  (2) go to site VPN - VPN policy remote router192.168.2.1 and click Edit

  (a) disable Netbios

  (b) select "None" from the drop-down list the remote IP address.

  (c) to apply the change

  3) go to the VPN-> VPN policy on the head end site (192.168.1.1) and click Edit

  (a) disable Netbios

  (b) select "None" from the drop-down list the local IP address

  (c) to apply the change

  Now all the traffic wil go down the VPN tunnel and exit to the internet on the site of head end. Hope this helps others with the same question.
