Routing VPN problem

• Static and NAT router to router VPN

  Hello

  I have two site VPN using routers. The VPN is fine, BUT - at the end of the seat, the customer has NAT entries static to allow incoming connections - any service that has a NAT static to allow incoming connections from the Internet is inaccessible in the same way. Ping, for example, doesn't have this problem because there is no static NAT entry. I tried to configure a route map-"No. - nat" according to the http://www.cisco.com/en/US/partner/tech/tk583/tk372/technologies_configuration_example09186a00800949ef.shtml , I thought I was working.

  H.O. has the IP 131.203.64.0/24 and 135.0.0.0/24 (I know, I know - I'm trying to change), and the R.O. 192.168.1.0/24.

  Bits of configuration:

  IP nat inside source overload map route SHEEP interface Ethernet0

  IP nat inside source static tcp 135.0.0.248 131.203.100.27 3389 3389 extensible

  (other static removed)

  Int-E0-In extended IP access list

  ip permit 192.168.1.0 0.0.0.255 any

  (other entries deleted)

  access-list 198 deny ip 131.203.64.0 0.0.0.255 192.168.1.0 0.0.0.255

  access-list 198 deny ip 135.0.0.0 0.0.0.255 192.168.1.0 0.0.0.255

  access-list 198 allow ip 135.0.0.0 0.0.0.255 any

  SHEEP allowed 10 route map

  corresponds to the IP 198

  1 remove the static entry for the specified host the VPN problem, but obviously breaks things :(

  2. as mentioned, the VPN itself works fine, I can ping hosts perfectly.

  Any help greatly appreciated :)

  Thank you

  Mike.

  You must use the option of the route to the static NAT map. This is a new feature in 12.2 (4) T according to this page:

  http://www.Cisco.com/univercd/CC/TD/doc/product/software/ios123/123cgcr/ipras_r/ip1_i2g.htm#1079180

  He must do exactly what you want. The old, another way to do is use "The thing", where you create a loopback interface and don't make a nat interface and use routing strategy for routing VPN traffic to one address on the same subnet as the loopback interface, but not the address of the loop. IOS then that réacheminera traffic to the real destination (in this case the remote VPN site), but since now it is not a 'ip nat inside' interface, the static nat translations does not apply and the VPN traffic will not be translated. The problem with this solution is that all loopback traffic is switched to the process, so it is a bit of a hack, but these things are sometimes necessary.

• Unusual routing VPN configuration

  Hi, I use a PIX 525 to our main site, and one of the remote sites using a router in 1721. The 1721 connects to the LAN. All traffic is forced to use a virtual private network between the remote sites and main. The intention was to force the internet traffic from the remote site through the filter of content on the main site, rather than use the split tunneling to leave straight out to the internet through their DSL connection.

  The problem is that, of course, internet traffic this VPN comes back the PIX, Internet. Our content filter reflects the way of the switch connected to the internal interface of a PIX.

  I need to find a way to route VPN traffic from the remote site to an ethernet on the PIX interface which will be connected to our switch stack. If I can do this without breaking the VPN, traffic should be filtered on the main façade and through VPN to the remote side.

  Yes, you're pretty much toast unless:

  you choose to configure a web proxy to Headquarters and set up remote PCs to use it. In this way, they use a proxy that is located behind the 8e6.

  Same pix os 7 will not help, as all nat occurs on this topic - just remote communication will flow through the pix, never hit its physical interface or internal switch ports inside and so the 8e6.

• TFTP router VPN if

  I can't TFTPing a configuration of my router 851 to my computer via a VPN IPsec tunnel that this router is connected.  I'm able to telnet and ping all devices on the far - end without problem.  I can TFTP configuration of a switch behind the router, no problem.  I'm guessing that this problem is related to an ACL on the router. I also have problems to connect to this router by using the Cisco Config Professional.  Discovery failure, with connection could cannot be established or HTTP service is not enabled.  I enabled the HTTP service.  The CCP works very well when I'm on the subnet of the router.  Any help much appreciated.

  For TFTP, you need to specify the router LAN interface (or the interface of the router which is part of the Cryptography subnet ACL) using the following command:

  IP tftp source-interface

  Here's the order reference:

  http://www.Cisco.com/en/us/docs/iOS/fundamentals/command/reference/cf_f1.html#wp1011314

  For the connection of the CCP, what ip address you are trying to reach the router on? and also you have a any restrictions on who can access the router via HTTP? Please share the 'ip http' configuration you have on the router.

• Route VPN site to site on one path other than the default gateway

  I want to route VPN site-to-site on one path other than the default gateway

  ASA 5510

  OS 8.0 8.3 soon

  1 (surf) adsl line interface default gateway

  line 1 interface SDSL (10 VPN site-to-site)

  1 LAN interface

  What's possible?

  Thank you

  Sorry for my English

  Here is the assumption that I will do:

  -Your IP SHDL is 200.1.1.1, and the next hop is 200.1.1.2

  -Your LAN-to-LAN ends on this interface (interface card crypto SHDL)

  -VPN peer 1 - 150.1.1.1 and LAN is 192.168.1.0/24

  -VPN peer 2 - 175.1.1.1 and LAN is 192.168.5.0/24

  This is the routing based on the assumption above:

  Route SHDL 150.1.1.1 255.255.255.255 200.1.1.2

  Route SHDL 175.1.1.1 255.255.255.255 200.1.1.2

  Route SHDL 192.168.1.0 255.255.255.0 200.1.1.2

  Route SHDL 192.168.5.0 255.255.255.0 200.1.1.2

  Hope that helps.

• IOS router + VPN + ACS downloadable IP ACL

  I want to use the function "Downloadable IP ACL" 3825-router VPN (OI 12.4 T) in combination with a CBS.

  In many documents and discussions, I read that it is possible to use the DACLs on "devices Cisco IOS version 12.3 (8) T or higher.

  Authentication and authorization by the AEC works and the device gets some settings of the av-pair-feature.

  I have tried several things to apply the DACL as the use of av pairs or ACS "Downloadable IP ACL" function, but nothing works.

  In the debug log, I see that the av pair is transmitted to the device, but it is not used.

  --> Can you tell me, is it possible to use the DACLs on the IOS routers?

  --> How does it work? What can I change?

  --> Is there a good manual to apply it?

  Thanks for your help!

  Martin

  It would be useful to know the PURPOSE of what you're trying to do...

  AFAIR client config mode requires no ACL for filtering short tunnel split ACL... and I have no way to test right now.

  If you want to allow or not some clients access to certain subnets why not investigate tunneling ACL and vpn-filter in combination with ACS split will rather than for the DACL.

• Problem on site to site and between router vpn client series 2,800

  Hello

  I need a little help.

  I have 2 office of connection with a site to site vpn

  Each site has a dry - k9 router 800 series.

  Each router has actually client ipsec vpn active and all users can connect by using the client vpn with no problems.

  I added the lines for the vpn site to another, but the tunnel is still down.

  the site at the other tunnel is mounted, but it does not pass traffic; What is the source and destination ip on the router that you are trying to ping the address

  whenever you try to open the traffic from router A to router B, you must to the source of the traffic.

  for ex,.

  Router A-->10.1.1.1--fa0/0

  Router B - 172.168.1.100

  source of ping 172.168.1.100 router # 10.1.1.1

  After doing the pings, send the output of the show counterpart of its crypto ipsec at both ends

• Cisco IOS - access remote VPN - route unwanted problem

  Hello

  I recently ran into a problematic scenario: I am trying to connect to a remote LAN (using a Cisco VPN client on my windows xp machine) my office LAN and access a server there. The problem is that I need a remote local network access at the same time.

  Remote LAN: 172.16.0.0/16

  LAN office: 172.16.45.0/24

  Topology:

  (ME: 172.16.10.138/25) - (several subnets form 172.16.0.0/16) - (Internet cloud) - (VPN-Gateway) - (172.16.45.0/24) - (TARGET: 172.16.45.100)

  To provide access, I configured a VPN to access simple distance on a 1700 series router. It's the relevant part:

  (...)

  crypto ISAKMP client config group group-remote access

  my-key group

  VPN-address-pool

  ACL 100

  IP local pool pool of addresses-vpn - 172.16.55.1 172.16.55.30

  access-list 100 permit ip 172.16.45.100 host 172.16.55.0 0.0.0.31

  (...)

  The configuration works fine, I can access the 172.16.45.100 server every time I need to. However, the problem is that when the VPN connection is connected, Windows wants to somehow rout the packets intended for 172.16.0.0/16 through the VPN tunnel. This is apparently due to a static route that added by the Cisco VPN Client and all other specific VPN routes.

  I suspect that the culprit is the IP LOCAL POOL, since when the VPN is connected, debugging of Client VPN log shows something like "adapter connected, address 172.16.55.1/16. Focus on the part "/ 16". I checked the VPN status page and the only road indicated there was "172.16.45.100 255.255.255.255" under remote routes. Local routes was empty.

  Is this a known problem I missed the obvious solution for? Is there no workaround apart from the pool local vpn penetrating high-end 10.x.x.x or 192.168.x.x? Thank you in advance for advice or tips!

  Hello

  The best way is to avoid any overlap between the local network and VPN pool.

  Try 172.17.0.0/16, is also private IP address space:

  Please rate if this helped.

• 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

  At the Office I have a Server SBS 2011 Premium, cable modem Comcast/SMC 50/10 in the bridge, a NetVanta 3450 with port 1723 transmitted router, the VPN wizard ran over and over, I made the best practices recommendations, the firewall server is disabled, but I can still not log.  Can I VPN in other places of the House.  What Miss me?  The PE Dell R510 is multi-aiguise with 3 NICs, but I use one of them.  Would that be a problem?  Thanks, Craig

• [FIXED] VPN problems

  Hello.

  I'm trying to set up a VPN server on my XP machine at home, in order to circumvent the blocks to internet on my school's network. I managed to set up a VPN server on my laptop with WIN7, but I do not run all the time, so I thought it would be more convinient to set up VPN on my old XP computer.

  in any case, I think that I did everything what I'm supposed to. I have forwarded port 1723 in the router and open port 1723 and Protocol 47 (GRE) IP in the firewall. I also chose ports in the internet connection for the VPN properties, which do not mix with the DCHP server on my router.

  However, still, when I try to connect from the network of my school, I get error 800 or 807. Can someone help me? What Miss me?

  OK, so I found what my problem was. The local IP address for my XP computer has been updated with an IP address outside the range of the DHCP server on the router. Once I changed the IP address, forwarded the ports to the new IP address and configure the VPN server again, it worked.

• Connect to the router VPN using PPTP (Ubuntu)

  Hello

  As I mentioned in other post, I try to get the VPN works for my Ubuntu workstation. I'm not an expert of VPN, so I need help.

  So far, people seem to agree that pptp is easier to config that IPSec (under Linux platform). Select the PPTP Protocol and add a user account for the Linksys router.

  Now, the Linux part.

  I have pptp-linux installation (it is the best client for linux pptp seams). I try to set it up, but I missed something relatd to coding or something.

  I try to follow this documentation: https://help.ubuntu.com/community/VPNClient#PPTP

  When I run this command: pon myvpn nodetach

  I get the following error:

  Using interface ppp0
  Connect: ppp0 <-->/dev/pts/2
  MPPE required, but not executed [v2] MS-CHAP authentication.
  Connection down.

  Here is the log of the router:

  15 Oct 21:51:02 2008 Client Remote System Log [] disconnect PPTP server.

  Kind regards

  Hello

  Thanks for your help and this useful link.

  I have change my configuration file and I managed to set up the pptp connection.

  Here the configuration file that I use (for people with the same problem):

  RemoteName until-vpn
  LinkName until-vpn
  ipparam entmd-vpn
  Pty "pptp exemple.dyndns.org - nolaunchpppd.
  name budderball
  usepeerdns
  require mppe
  garbage-eap
  /noauth
  file /etc/ppp/options.pptp

  Also, I change the contents of/etc/ppp/chap-secrets:

  Budderball until vpn-based *.

  With this configuration, I can launch the tunnel and communicate with the gateway and LAN.

  Here the command line I use to establish the connection and than create road so that any request for 192.168.1.0/24 use the ppp0 interface.

  sudo pon entmd-cpn debug dump logfd 2 nodetach

  sudo route add - net 192.168.1.0 netmask 255.255.255.0 dev ppp0

  Finally, by reading the documentation, I found a plugin for Network Manager. It's a work like a charm.

  For ubuntu: sudo apt - get install network-manager-pptp

  An installation, you must restart to 'activate' the plugin. (this is a bug)

  You can use the network - manager to configure your pptp connection. I intend to post a wikiw on the Ubuntu Wiki page.

• VPN problem taking in charge the VRF CSR

  Hello community,

  I am currently evaluating CSR at AWS (60 day trial) and already around the usual problems and specialty architecture network AWS design.

  I can't open a TAC case, because we purchased no license. We will, once this last problem is solved.

  Current configuration:

  • Two councillors in a VPC in two AZs
  • Transit between two advisers of the GRE tunnel
  • running supports the BGP VRF
  • using door VRF
  • the RSC is connected to several AWS VPC (customers) via the AWS VPN feature - route entirely mesh based VPN--a VRF customer - all running with BGP
  • Link to local is done in the same way: entirely mesh route based VPN - using door VRF - all running with BGP
  • VRF import/export rules

  It works fine - no problems here. All HA tests work as expected. So far, so good.

  Now, we had to create a VPN connection to a special local location of our society. We should create a policy based VPN location (no support for VPN road based there). It is a two-to-one VPN. Two advisors of the connection to a gateway onPrem. The two tunnels, run the same field of encryption. OnPrem routing is based on the State of the tunnel. We put this tunnel in the VRF door of entry. Routes are injected to the door VRF routing table by VPN process (reverse-way static in crypto map). To get these exported to consumer VRF routes, there is a network statement in door VRF BGP process.

  Well, this also works fine if we do this only with CSR A. Reachablity is out. CSR B the delivery of the CSR due to taking work supported the VRF VPN. However, if we establish the second CSR B tunnel, there is something strange happens.

  Tunnel is very well implemented. Traffic through the tunnel at CSR B is accepted and routed to the destination. Created at door VRF on CSR B traffic is routed in its own VPN very well. However, traffic from a VRF client who reached CSR B (traceroute proved that) is not routed through the VPN tunnel, despite the VPN client routing table is to say. CSR A running the same configuration, there is no problem. Only on the CSR B.

  I don't understand this. If remove us the configuration of the tunnel of CSR and create only tunnel on CSR B, it still does not. I don't understand why, because I did a comparison of config and found no difference.

  Someone at - it an idea, whats going on?

  How can I debug this problem?

  CSR - A:

  B 172.29.13.176/28 [20/0] via 1.1.119.182 (vrf - default), 3w4d

  CSR - B:

  with route (doesn't work is not for the customer VRF)
  B 172.29.13.176/28 [20/0] via 1.1.119.182 (vrf - default), 00:00:02

  No itinerary (work, because only sent by public transit to the CSR - A)
  B 172.29.13.176/28 [20/0] via 192.168.254.53 (vrf - default), 00:38:23

  This problem is hard to describe, I would really appriciate discuss with a TAC engineer in a WebEx. Is this possible?

  Thank you.

  Hello Tobias,.

  The problem you describe is going to be outside our CSR platform expertise. Looks like the CSR works well and HA works as well, and now you're trying to find a solution to a problem of network/VPN that you are facing.

  Our team is led to find an internal resource to resolve your issue, please allow us a day or two to get back to you with an answer

• 5 routing VPN site

  Hi all

  I threw myself little in this project without a lot of lead in.  Basically, we have 5 sites

  Site A: HQ with ASA 5520

  Site B: Remote with 5505 with L2L at Site A

  Site C: Remote with 5505 with L2L at Site A

  Square D: distance with 5505 with L2L at the Site

  Site E: Remote with 5505 with L2L at Site A

  In an emergency, I had to get phone running systems when a T1 PTP line was cut at the beginning by the customer! I created a VLAN on each phone named 5505 and created the Tunnels of VPN L2L all return to the HQs 5520.  Everything was good in the neighborhood, phones were talking about main PBX server to HQ, we could compose and in no problem.  The problem is now the phone Vender tells us that we need routing between each site. We cannot compose between each remote site without using external number (whereas before you dial internal extensions in order to reach all other sites)

  Site B needs to talk to the PBX to C, D and E (A, obviously as well but that is already at work) and so on.

  I found topics dealing with 2 remote sites requiring a routing, however, with 4 that all need to routing to the other configs will very quickly very vast and complicated.  There is already extra virtual private networks to of the HQ 5520 who go elsewhere and a good amount of security configurations, so the config is already pretty decently sized.

  Is there a better way to do this, or should I start to write my setups now?

  If I understand your question, you need to configure a list of VPN networks on each VPN Ray and the hub.

  For example on the RADIUS B a crypto access list that is similar to:

  ip-> A B permit

  ip-> C B permit

  ip-> D B permit

  ip-E > B permit

  corresponding Cryptography ACL on the hub for talks would be like:

  IP-> B to allow

  IP C-> B permit

  allow the ip D-> B

  E-> B ip license

  Repeat for each Department accordingly.

  So basically your configuration crypto would ' t grow, only the ACL crypto.

  You can work with groups of objects to simplify the ACL crypt, in this case:

  Crypto ACL on Hub B:

  object-group VoIP-dst

  object A

  object C

  object D

  object E

  object-group VoIP-src

  object B

  permit ip src VoIP VoIP-dst

  And so on...

  Just make sure your config allows same-security-traffic intra-interface
