Pix IPSec support

Hello

I'm trying to set up a tunnel to PIX-501 6.3 version. It's an old device that needs to be replaced soon, but unfortunately we have a tunnel now...

I used this document as reference (6211): http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a0080094761.shtml

The remote end is a sonicwall.

The problem seems to be that the pix never sees interesting traffic for the tunnel and never tries to establish a connection. I activated the ipsec encryption and debugs isakmp crypto, but no data is never displayed, even when you try to access a device on the remote side of the tunnel!

Someone tried to implement this feature with some tunnels in the past, but never succeeded, so I think it can stay commands in the running-config causing problems...

I'm grilled at this stage, so any help would be greatly appreciated. I will provide all necessary information as needed.

Thank you very much.

The issue is your inside interface/subnet has been configured as a 16 network and it duplicates the remote network.

The inside interface: 172.21.25.254 (mask: 255.255.0.0), and network remote 172.21.19.0/24 also falls under the same subnet.

Instead of routing the packet, inside host will try to proxyarp for the destination that they think they are in the same subnet, so does not.

Try changing the inside interface with 24 subnet if you want to keep the same IP address and also change the mask of 24 inside your host.

Otherwise, you need to configure NATing to a completely different subnet to the remote 172.21.19.0/24.

  • Road by default from version 6.3 PIX IPsec tunnel

    We have a PIX 501 running IOS version 6.3.1.

    There are currently 3 tunnels IPsec active as described below.

    What we would like is to have all traffic by default (0.0.0.0 0.0.0.0) range out through the tunnel of the middle line so that traffic can be protected by a firewall on the other side of the tunnel.  Since ICF is a Sonicwall what would be needed to be changed in the configuration on the PIX to get there?

    Hello

    You do not configure really any type of default route for the VPN L2L. You match rather traffic with 'everything' destination on configuring VPN L2L. Basically you would like to configure the VPN L2L ACL encryption with the 'whole' destination map

    I guess in your case it would be the ACL named "103".

    access-list 103 allow ip 10.10.5.0 255.255.255.0 any

    IP 10.10.5.0 doesn't allow any access list 103 255.255.255.0 10.10.1.0 255.255.255.0

    Naturally, your NAT0 ACL configuration should also reflect this change. I guess the end remote Sonicwall'd private NAT to public Internet access in this case whereas. I guess that in this case, the ACL NAT0 might even be just this one rule ACL

    access-list 101 permit ip 10.10.5.0 255.255.255.0 any

    BUT what I was asking however for now mainly is the fact it has a priority of '11' in the 'crypto map' which has between 2 other L2L VPN connections.

    peer11 card crypto ipsec-isakmp 10

    correspondence address 10 card crypto peer11 102

    peer11 card crypto 10 peers set 75.95.21.41

    peer11 card crypto 10 set transform-set pix11

    11 peer11 of ipsec-isakmp crypto map

    correspondence address 11 card crypto peer11 103

    11 peer11 peer Sonicwall crypto card game

    card crypto peer11 11 set transform-set pix11

    12 peer11 of ipsec-isakmp crypto map

    correspondence address 12 card crypto peer11 104

    card crypto peer11 12 set peer 75.62.58.28

    card crypto peer11 12 set transform-set pix11

    If you have changed the destination address of '103' crypto VPN L2L ACL at "" I guess that would probably cause so that the last connection VPN L2L with "12" priority may stop working since the previous connection already corresponds to 'all' your network 'inside' destination address.

    The solution might be to delete the current configuration of the '11' priority and add it with '13' for example, so that the other 2 connections VPN L2L could continue to work and all the rest of the traffic would be passed to the connection VPN L2L with Sonicwall as the remote peer.

    No crypto map ipsec-isakmp 11 peer11

    no correspondence address 11 card crypto peer11 103

    no set of 11 peer11 card crypto don't peer Sonicwall

    No peer11 11 set transform-set pix11 crypto card

    13 peer11 of ipsec-isakmp crypto map

    correspondence address 13 card crypto peer11 103

    13 card crypto peer Sonicwall peer11 game

    card crypto peer11 13 pix11 transform-set game

    I have to say that this is how I expect it should work. I worked with VPN L2L that have been configured in this way but its quite rare.

    If you want to try something like that, of course, be ready to return to the old configuration with your admins of the remote peer, if things do not work. I guess more difficult configurations changes must be made on the remote end while your configuration of the ends should be fairly simple.

    Hope this helps

  • PIX IPSec configuration

    Hello

    We have configured our PIX as below.

    Here, I would like a clarification on implecation access lists.

    I joined 'infinet1' crypto map and 'acl_out' - list access to the external interface, if any traffic entering under "infinet1" of the lists of access such as 101, 102, 103 etc. will again suffer conditions of access 'acl_out"list or not?

    We have seen that this is not the case!

    the conditions of "acl_out" work correctly with the rest of the traffic which is not under the control of IPSec accesses-lists.

    I need to enforce these conditions "acl_out" IPSec traffic too... How can I do?

  • PIX IPSec and ACL issues

    Hello

    On a PIX 515E v.6.3.5.

    There are three lists ACL that can come into play when setting up an IPSec VPN on a PIX? (I hear a sound of 'It depends')

    1 Nat (0) ACL - NOT NAT traffic, it is part of the IPSec VPN

    2 crypto ACL - ACL that distinguishes if the traffic is destined for the IPSec tunnel.

    3 ACL - ACL to allow | deny traffic after ACL #1 and #2.

    #3 "Allow packet IPSec to bypass the blocking of access list" If the "ipsec sysopt connection permit" command is configured and ONLY for the #3 ACL? In other words the sysopt does not participate on ACL #1 or 2 above?

    The mirroring of the ACL, which is suggested (required) to both sides of the tunnel IPSec applies to what ACL?

    Thank you

    It depends on

    (1) is not always used, because with a site to site VPN sometimes you need to NAT your addressing internal

    (2) always necessary

    (3) if the "ipsec sysopt connection permit" is set up any ACLs on the interface where the VPN is finished is bypassed. If it is not enabled then once packets are decrypted they are then checked against the acl.

    Mirrored ACLs is required.

  • PIX IPSec VPN with Cisco 877W

    Hi all

    I am trying to create a VPN between a PIX and a Cisco 877W tunnel but can't seem to get the tunnel. When I do a 'sho crypto session"on the Cisco 877, I get, he said session state is declining, then changed to NEGOTIATE DOWN, but it is now down again... Please find attached the configs for both ends... Are there commands to confirm that the tunnel is up other than to try to ping the remote end? I would greatly appreciate any help lift this tunnel.

    Kind regards

    REDA

    Hello

    Based on the configurations of joined, to do some changes. For example:

    1. the isakmp policies do not match on the router and the pix. Make sure the hash group Diffie-Hellman and life correspond on the 877 and pix.

    2. the access list for the ipsec traffic must be images of mirror of the other.

    3. make sure life of ipsec on the two peers.

    I hope it helps.

Cisco VPN clients authenticate with the credentials of group fine, but is it possible to use local users to authenicate plu? We use local users to our existing PPTP VPN clients, but we want to migrate these users to IPSEC. Any info would be greatly appreicated.

    I'm confused if this will support IPSec or not because at one point, he said C2951UK9-1520IT that supports IPSec and on the other side he said SL-29-IBP-K9 which only supports basic configs.

    A normal case would be something like

    SL-19-IPB-K9 Basic IP for Cisco license 1900
    SL-19-SEC-K9 License security for Cisco 1900

    which means a base license and then added a license of security so that the work of crypto.

    Hello Boy Communication

    On older hardware (1800/2800 etc. and more) you need to select the software image containing the features that you need (e.g., advanced ip services) and you didn't need a license.

    On the ISR G2 (1900/2900/3900), there is only a single ('universal') image that contains all the features, but some features (such as IPsec) are 'locked' and you need a permit to 'unlock'

    So in your case the universal image (C2951UK9-1520IT) "supports" IPsec in the sense that the function is in the software, you don't need to order/download any other software image, however the IPsec have only be available if you enable a security licence (SL-29-SEC-K9 or SL-29-SEC-K9 = or L-SL-29-SEC-K9 =)

    (Note that at the end you have cited references for 1900 licenses, not the 2900).

    4.4 mine (7) seems to do.

    Hi grantchen,

    I think that ssh version 1 is supported from version 5.2. 5.2 only supported in ssh version 2. You must have a newer version for this.

    You can take a look at the following ADDRESS:

  • IPSEC tunnel and Routing Support protocols

    Hello world

    I read that IPSEC does not support routing with VPN's Site to the other protocols because both are Layer4.

    This means that if Site A must reach the B Site over a WAN link, we use static IP on the Site A and Site B router?

    In my lab at home I config Site to Site VPN systems and they work correctly using OSPF does that mean that IPSEC supports the routing protocol?

    IF someone can explain this please?

    Indeed, solution based purely crypto-card are not compatible with a routing protocol.  Crypto card however is the legacy config we support on IOS. The best practice is to use the protection of tunnel. Any routing protocol would work then.

    for example

    It's the best solution we currenty have

  • PIX and NAT - T

    Hi all

    I have a small question. I have a couple of users who use routers to connect by VPN to our pix that authenticates by a RAY for L2TP connections. I enabled the NAT - T on our PIX and they may not always connect. Is there anything I might have missed. I checked most of the posts in this forum do not see anything else, I should have activated.

    Can anyone help?

    Thanks in advance.

    A tunnel of Lan-to-Lan of a router in a PIX does not NAT - T, unless there is NAT devices between two end points. If this is the case, you must ensure that both the software both from the end of rehbeh points devices support this capability. An example of a router to tunnel PIX IPSec configuration is available at http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a0080094498.shtml

Could you please send me the instruction or the link to configure vpn? Also, I don't have the vpn client to test my vpn, how what to do? As you can understand my question, I am new to cisco gear... Thank you.

    Hello

    I'm guessing that you need one of these two virtual private networks.

    -Remote access VPN: where remote allows the Cisco VPN client users to access the resources of the company

    -Site to site VPN: where two systems with IPSEC support establish a VPN tunnel, allowing the internal LAN from different termination points (offices) communicate.

    You can find these two examples on the url you gave.

    If the remote access, I'd watch

    http://Cisco.com/en/us/products/ps6120/products_configuration_example09186a0080702992.shtml

    And then also look at how to set up the split tunneling, then the home user can access the resources of the business AND Internet.

    For the site to site VPN, it depends if your device is a PIX / ASA or a router.

    It will be useful,

  • Several VPN clients behind PIX

    Multiple users in our company have establish a VPN client connection to a VPN Internet gateway. The connection must go through our PIX. I already active correction for esp - ike Protocol and this allows a user to get out. When following users try to configure a VPN connection to the VPN gateway on the internet, the following syslog error appears:

    3 PIX-305006%: failed to create translation portmap for udp src inside:192.168.0.102/500 dst outside:1x5.x17.x54.x10/500

    It seems to me that the PIX only supports an outbound VPN client connection at the time. Is this true?

    When I perform a clear xlate, first user disconnects, but new users is able to establish a VPN connection.

    Kind regards

    Tom

    That's right, Tom - in the release notes for 6.3 (1), the PAT for ESP section says "PIX Firewall version 6.3 provides protocol PAT IP 50 capacity to support unique outbound IPSec user."

    If you have enough public IP addresses and the remote VPN gateway supports PPTP, then a means to achieve multiple outbound VPN connections would be to set up a separate pool of the NAT for users who require outbound access and assign internal IP addresses of those users to use these addresses.

    Having had just a quick look around, if PPTP is an option, then the PPTP PAT 6.3 support can help.

  • Client pix VPN how to authenticate with Active Directory

    Hi all, I've just set up my first Client VPN on a Cisco PIX. Everything works very well so that hitting the correct subnet and logon. However, I would like to see how I can get my connection of remote users with there active directory accounts. Right now I use the local connection for the pix for testing purposes. Sounds easy, but I'm missing something

    We use:

    Cisco Pix 515E version 6.3 (3)

    Thank you

    Dan

    Unfortunately the PIX 6.3.3 version does not support Active Directory authentication. V6.3.3 PIX only supports authentication to the server database, radius, and Ganymede local PIX.

    If you want to authenticate to active directory, it is support for PIX v7.x go.

    Here are the different types of authentication support for PIX v7.x leave for your reference:

    Hope that answers your question.

  • ASA at PIX VPN - routing

    Hi all, I built a site 2 site between an ASA 5510 and a PIX IPsec tunnel.  The tunnel is up, and most of the time the traffic flow between source and destination LANs as planned. The problem is that we need the ASA to send syslog messages in the VPN tunnel to a syslog on PIX site server.  If I get a router on the ASA website, I ping the site of PIX syslog server.   The following statement is in the ASA:

    Route out of pix.net.addr sub.net.mask next.hop

    But in the journal of the ASA, I see messages "Routing failed" for the traffic of the SAA on the syslog server.

    April 8, 2010 08:32:01 ASA5510: % ASA-6-110003: routing could not locate the next hop for icmp NP identity Ifc:10.xx.x.xx/0 to inside:172.xx.x.xx/0

    Any thoughts?

    Thank you

    Robert

    Hello

    Public IP address of the ASA must be in interesting for this tunnel traffic (since it's the INVESTIGATION period where newspapers are going to be sent from).

    Also, the IP address of the syslog server must be in the interesting traffic.

    In other words, you should be able to PING from the ASA to syslog (through the tunnel) server.

    Federico.
