• VPN problem - "C1712 behind router Linksys ' connection to PIX515e

  Hi all

  I have a question about VPN (lan-to-lan).

  My setup is the following:

  10.1.20.x-[PIX515e_central site VPN concetrator]-(( ISP ))-[LINKSYS BEFSX41 router]-[Cisco1712_branch] - 192.168.14.x

  I would like to create tunnel VPN between C1712 and PIX515 (lan-to-lan), so users of 192.168.14.x would be able to connect to servers located on a central site in network 10.1.20.x.

  NAT - T is manually enabled on PIX and 'IPsec passtrough' is enabled on the Linksys router. Then what should I do now to create a VPN tunnel?

  What is the basic C1712 and PIX515e configuration to make it work?

  All other industries (8) work, but they are directly connected to the internet via C1712, so without router Linksys in front of him. Thus, PIX is already properly configured for this configuration.

  I guess that the installer with Linksys router does not work because of PAT.

  6.3 (4) version PIX

  C1712 Version 12.4

  Please advise!

  Thank you very much in advance!

  This line is incorrect on the router configuration:

  IP nat inside source list 6 interface FastEthernet0 overload

  Please, remove it and have her take:

  overload of IP nat inside source list 101 interface FastEthernet0

  Hope that solves this problem.

• VPN to ASA behind router

  Hello

  I have ASA 5505 behind a router, which is also a dmvpn (the router), on my ASA RADIUS I configured a remote access vpn.

  But when I try to forward the VPN ports to my asa, I get problems with stability, with my talk about vpn on the router.

  Is it possible to have a dmvpn to the router and vpn for remote access to my ASA?

  I have attached the running configuration.

  Thank you

  Joelle,

  The problem here is that your router and the ASA want to use udp port 500 and udp port 4500.  Of course if you forward incoming ports then the dmvpn is not going to work and vice versa.  What you can try to have your ezvpn use ipsec-over-tcp on port 10000 and that transmits to the place.

  On the SAA configure "crypto isakmp ipsec-over-tcp port 10000.

  On the change of the client connection information, click the transport tab and select ipsec-over-tcp.

  On the router port forward tcp 10000 to the ASA.

  Hope that helps.

• 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.

• Site to site VPN with router IOS

  I want to create a VPN site-to site on the Internet. On the remote site, aside from the VPN to the head office, there should be no traffic not allowed in internal from the Internet to the network and that there should be no traffic from the internal network to the Internet allowed. The internal network will run a private 192.168.x.x address range.

  I'm going to use a Cisco 2811 router integrated of services on the remote site and this will last an IPSec VPN that will end a hub at Headquarters. I understand that this router has an IOS and IPS firewall built in.

  Would I be right in thinking that because I don't want to have access to the Internet (except VPN) or should I configure IOS firewall features on the router? And there is no point in the configuration of the features IPS wouldn't?

  My thought is that only an entry in list of unique access to deny pi a whole applied inbound to the interface that connects to the Internet would be the best strategy. I think that the command "sysopt connection permit-ipsec" should allow the VPN to form even with the ip address to deny any any ACL (or is it just a Pix command? If Yes, then I have to allow ESP and UDP 500 (ISAKMP) from the public address of the hub at Headquarters to allow the VPN to form wouldn't I?).

  Think I'll probably expand slightly the access list to allow the icmp Protocol, ssh and https traffic from the IP address of firewall seat outside so that I can monitor the remote site and access it safely if the fail VPN.

  And I wouldn't need one access list on the interface connected to the internal network I would like because the range of addresses would be not routable, so they would not be able to initiate connections to the Internet (all the trffic to the remote site is specified under a valuable traffic to bring up the VPN)

  Use one of the IOS Firewall inspect commands or the IPS would be useless and have no effect in this case wouldn't it?

  I really just need to know if the ip address to deny any any ACL on the external interface on the remote site is the best solution (and the simplest), and whether it will be safe.

  We used to use fiewalls Pix for remote VPN site to site, Amazon refuse incoming connections on the external interface by default but now I have been informed that these series 2800 routers will be used later, so I would get my thoughts straight and be able to build safe to do the same work all existing PIX are doing (they are all installed for just the VPN at Headquarters as in) the first paragraph).

  I would like any advice or thoughts on the subject. I don't know there must be a ton of people who put routers for the same purpose.

  Thank you in advance.

  Pete.

  I did a lot of implementations site VPN to another using IOS routers. They work very well. Based on my experience I offer these comments and I hope that they will help you:

  -you don't want a list of incoming access on the external interface, but you want more in it than simply refuse an ip. There is no permit-ipsec sysopt connection in IOS so you want to certainly allowed ISAKMP and IPSec/ESP. I suggest that you also want to allow SSH. I would like to allow ICMP but only starting from the address space of the network head end. I do not allow HTTPS since I generally do not allow the http server on the router. If you want HTTPS then certainly enable it. To facilitate the ping and traceroute on the remote I frequently allow icmp echo-reply, timeout and unreachable port from any source.

  -I want to put an inside interface access list. There are certain types of traffic that I don't want to send from the Remote LAN. I have usually refuse any trap SNMP or snmp for LAN devices and refuse out of the local network icmp redirects. I also often configure RPF controls inside interface to catch any device which is misconfigured.

  -If you want to allow SSH when the VPN is not active (and I highly recommend that you do) then you will probably need to configure at least 1 (and maybe more) users and password of the router ID. And you want to configure authentication on the vty use local authentication if the head end authentication server is not available.

  -I'm not clear from your description if you plan to run a dynamic routing via the VPN Protocol. I wish I had a dynamic routing protocol because I want to announce a default route to the remote control via the VPN. I do not locally configure a default route on the remote router. This way if the VPN tunnel is up there is a default route pointing to the tunnel and if the VPN tunnel is not up then there is no local route by default and users on the remote database can not access the Internet. It is a simple and very effective method to ensure that all user traffic must pass through the central site.

  -regarding the routes defined on the remote router, my approach is that I define a static route for the endpoint of the tunnel to allow the tunnel to implement and I set up static routes for the subnet to the head of line I can SSH. And I do not configure other static routes the on the remote router.

  -You probably want to disable cdp on the external interface and also to disable the proxy-arp (and I don't make any ip unreachable).

  -There is frequently a problem when using VPN site-to-site with fragmentation. If a device on the local network sends a frame of maximum size, and then the router needs to add additional headers for IPSec, then the frame is too large and requires fragmentation. I like to use tcp adjust-mss ip to control the chunk size for TCP traffic and avoid any problems with fragmentation.

  -I don't think you want to set up the firewall or IPS from the features of IOS on the 2811.

  I hope that your application is fine and that my suggestions could be useful.

  [edit] after posting my response, I read through your post again and realize that you make to a VPN concentrator. The approach I have proposed on the execution of a routing protocol works for me because I usually have a router IOS in mind. It would not work to connect to a hub.

• PIX: Dialin routing through a different VPN VPN

  Here's the scenario: I have 2 PIX firewall on various sites connected to the internet with public (PIX A and B PIX) IP addresses.

  There is a permanent VPN site to site between the two and there is a clear separation between subnets between the two sites (internal network behind PIX is 10.10.4.0/24 and the internal network behind PIX B 192.168.0.0/16).

  I created dialin VPDN access to PIX for laptops to dialin via VPN - it currently allows access to the subnet 10.10.4.0/24 without problem.

  Now - I need these users of portable computers, when connects via the VPN to PIX has to be able to access the other remote site and access the subnet 192.168.0.0/16 of routing through the VPN site to site of PIX B.

  Is this possible? I would be grateful to anyone who helps with that. Thank you...

  This is currently not possible on the PIX as the PIX will not route traffic back on the same interface, it is entered in the.

  This feature will be available in the upcoming v7.0 version, which is currently in beta, so look out for it and you're ready to go.

• PIX-to-router VPN static-to-dynamic

  Dear friends,

  I'm trying to configure an IPSec tunnel between a router IOS and a PIX v7.0. I've seen some URL pointing here for a configuration example. However, this example only covers the v6.x PIX version, is not not helpful to resolve my case.

  My situation is that the router connects to a DSL provider and obtain a dynamic IP address and my PIX device has a static (Leased line) connection to the Internet. So, I have to establish the tunnel using preshared keys.

  How to make using v7.x on the PIX?

  Appreciate the help,

  Mauricio

  Mauricio,

  Here is an example for version 7.0 of PIX a tunnel L2L dynamic.

  http://www.Cisco.com/en/us/products/HW/vpndevc/ps2030/products_configuration_example09186a00804675ac.shtml

  You must create a dynamic encryption card, and use the tunnel defaultL2L-group for pre-shared key settings.

  The rate of this post, if that helps.

  See you soon

• Information on the routing of traffic of the client VPN to PIX.

  Hey all,.

  I could follow the VPN Wizard included in the PDM and able to connect with the VPN Clients for the PIX. But I'm looking for more information about how the routing is done.

  For example, my remote is 67.71.252.xxx and my inside is 192.168.1.xxx. But if I connect via VPN to PIX Client, all data is transferred through my VPN to PIX and then trying to get out to the Internet.

  I'll settle for data goes 192.168.1.xxx for transit through the VPN. This configuration made via the PIX or is it the responsibility of the Client machine to set up rules of the road?

  All links to the guides to installation, or technical notes would be great.

  Thank you inadvance.

  Hello

  I think the key word you are looking for is "split tunneling". This can be validated on the PIX using the vpngroup split access_list tunnel GroupName command.

  "Split tunneling allows a remote VPN client or encrypted simultaneous Easy VPN remote access device to the corporate network and Internet access. Using the vpngroup split-tunnel command, specify the access list name with which to associate the split tunneling of traffic. "

  In this example configuration: http://www.cisco.com/warp/public/110/pix3000.html, note that the same access list is used to "nat 0" and split-mining:

  access-list 101 permit ip 10.1.1.0 255.255.255.0 10.1.2.0 255.255.255.0

  (Inside) NAT 0-list of access 101

  vpngroup vpn3000 split tunnel 101

  Can't see anything obviously wrong with the configs. You have these connected back to back on the same subnet, it looks that it even if you have xxx out IP addresses? If so it's maybe a routing problem, in what they send everything to the default gateway of xxx.x.198.137 rather than to the other.

  Try to add a static route to the remote subnet to each PIX that points directly to the peer, so on PIX1 you should have:

  Route outside 192.168.1.0 255.255.255.0 xxx.x.198.138

  and on PIX2 do:

  Route outside 192.168.254.0 255.255.255.0 xxx.x.198.139

  and see if that makes a difference. Note that you wouldn't encounter this problem when these two PIX is on separate networks and uses the default gateway for all routing decisions.

  If this still fails, run 'debug cryp isa' and ' debug cry ipsec "on the two PIX are trying to build a tunnel again, and then and send us the output.

  Also, make sure your tests that you're rattling to a host behind a PIX to a host behind the other PIX, ping PIX to PIX or host because of PIX that won't test your VPN connection.

• Firewall router ios commands

  In order to solve problems that result from a problem with a vpn connection, where the router contains an ios firewall, knowing the correct controls are essential. What are the proper commands that should be used for the display of information related to vpn problems? For example, on a pix commands show conn, isa to show her, see the ipsec sa, sh help etc exlate in the determination of the issues. What are some commands which correspond to these and others can be used on a router with a firewall ios?

  Take a look at this link to learn more about the Cisco IOS Firewall.

• VPN via Pix 515

  Hello forum, I have a question please answer if someone knows the answer...

  Here is my scenario:

  Central location Pix515 (192.168.0.0/24)

  Location 1: (192.168.1.0/24)

  Situation 2: (192.168.2.0/24)

  Location 3: (192.168.3.0/24) local pool for vpn clients

  192.168.0.0/24, 192.168.1.0/24 lan - LAN IPSEC

  192.168.0.0/24 for 192.168.2.0/24 lan - lan IPSEC

  192.168.0.0/24 to 192.168.3.0/24 ezvpn IPSEC

  Question:

  Is it posible to connect Location1 and Location2 via Pix, or Location1 and Location3?

  On encryption ACLs on each location of traffic destined to another location is included for the encryption process.

  for example, location1 acl:

  Access 100 per 192.168.1.0 255.255.255.0 192.168.0.0 255.255.255.0

  Access 100 per 192.168.1.0 255.255.255.0 192.168.2.0 255.255.255.0

  Access 100 per 192.168.1.0 255.255.255.0 192.168.3.0 255.255.255.0

  other locations have a similar LCD-s

  There is no problem to access locations 192.168.0.0/24, but traffic between sites does not work.

  I think that pix encrypt packets outside ariving.

  I know, it's possible on IOS with IPSEC over GRE tunnels with some routing, but PIX?

  Republic of Korea

  Hi Rok-

  Allows traffic between VPN sites does not currently work with Pix OS 6.3.4 and earlier. Code pix 7.0, which will be published later this year, will enable traffic between the same interfaces of VPN security level. This will allow talked to talk communication. I have configured the week last with Pix 7.0 beta code, so I know this is a new feature and it will work.

  IOS does not have this limitation with IPSec. The GRE is not required to IOS to make communication speaks to talk work, although it can be used.

  I hope this helps you understand what is happening.

  Please let us know this that followed by questions that you have.

  Thank you!

• VPN concentrator + PIX on LAN-> customers can not reach local servers

  Hello

  I have a problem wrt. remote access clients coming via a VPN3000 concentrator and trying to access local servers.

  For the topology:

  The internal network is 10.0.1.0/24. It connects with the outside world, as well as via a PIX DMZ; the PIX has 10.0.1.1 in the internal network.

  On the same LAN (internal), I have the VPN concentrator for the inside address 10.0.1.5. It assigns addresses in the 10.0.100.0/24 range to the

  VPN client-PCs.

  I can sucessfully connect using the VPN client SW to the hub, i.e. remote access clients out addresses

  the 10.0.100.0/24 range.

  The problem: access from VPN clients to internal network is * not * possible; for example, a customer with 10.0.100.1 cannot connect to

  internal to the 10.0.1.28 server.

  To my knowledge, this is a routing problem because the server (10.0.1.28) has no idea on how to reach customers in

  10.0.100.0/24. The only thing that the server is a default static route pointing to the PIX, i.e. 10.0.1.1.

  So I set up a static route on the PIX for 10.0.100.0 pointing to the hub-VPN, that is

  Mylan route 10.0.100.0 255.255.255.0 10.0.1.5 1

  This does not solve my problem though.

  In the PIX logs, I see the entries as follows:

  % 3 PIX-106011: deny entering (no xlate) tcp src trainee: 10.0.1.28 (atlas) / 445 intern dst: 10.0.100.1 (pending) 1064

  The PIX seems to abandon return packages, i.e. traffic from the server back to the client

  To my knowledge, the problem seems to be:

  Short traffic VPN - client-> Concentrator VPN-> Server-> PIX - where it gets moved.

  My reasoning: the PIX only sees the package back, i.e. the package back from the server to the client - and therefore decreasing the

  package because he has not seen the package from the client to the server.

  So here are my questions:

  (o) how do I configure the PIX that I be connectivity between my remote VPN clients (10.0.100.0/24) and

  computers servers on the local network (10.0.1.0/24)?

  (o) someone else you have something like this going?

  PS: Please note that the first obvious idea, installation of static routes on all machines on the local network is not an option here.

  Thank you very much in advance for your help,.

  Hello, PIX the because can not route traffic on the same interface (prior to version 7.0 anyway), I suggest you two places your hub to the outside with the inside of the legs on a zone demilitarized or (if you can not do a makeover of the network) you remove your pool with 10.0.100.0 - addresses and create a pool with 10.0.1.0 - addresses which is a part of the address space. No, NOT all. A little book that it is not used inside.

• Automatic demotion of the Anyconnect Client (router IOS)

  Hello

  We run a Cisco Anyconnect client with a router IOS environment (2921) as the lead aircraft.

  We have upgraded the client package on the router to the latest version 3.1.13015. After installing this package on the customers, we discovered a bug. Windows-based computers are not able to establish a VPN connection more (authentication and auto-package-level still works, but then an error message is displayed ("unable to cannot" or similar).)

  I returned the package on the router back to an older version (3.1.11004), but is not beeing auto-installe when a client with the new version (buggy) connects.

  Is it possible to configure the router to force a downgrade to the customers, or is the only way to workaround to manually uninstall the package on clients?

  Thank you

  Heinz

  No you can't auto-downgrade the station clients.

  Unfortunately, you will need to uninstall it from the client end, then get the right package (older) of the router.

• Microsoft VPN client through 857 router ADSL

  Hello

  I've set up an adsl router 857 with CP Express (web interface) with a standard firewall and NAT configuration.

  router seems to work very well apart from connections outbound pptp.

  I can't use the MS VPN client to connect to our PPTP server in a remote location. I don't try to use VPN on the router 857, allow just to pass through of my laptop computer behind the router to an external vpn server.

  Instantly, the client goes to "Check Userbane and password" then crashes on this during a minute or two before failing.

  Any suggestions would be apprecated.

  Thank you
