• What do the acl when configuring a router as gateway VPN?

  Hi all

  my predecessor has set up our VPN gateway on our secondary router. Here's the relevant part of the config.

  ISAKMP crypto group customer VPN-CLIENT-HOST configuration

  key XXXX-XXXX

  192.168.177.7 DNS 192.168.100.1

  win 192.168.177.7

  XXXX.local field

  pool SDM_POOL_1

  ACL 104

  Im still trying to catch up in a few areas of programming and Im not sure this that set the ACL in this command is for or how it will affect users who connect to the gateway.

  Can someone point me in the direction of a useful Cisco document or explain it please? Ive been everywhere on Cisco's Web site and keep it going round in circles (its as if Cisco wants to sell me something; his tent like out of a Vegas casino without having spent the slots)

  Thanks in advance.

  Hello Paul,

  Parminder response is correct, this ACL is used to match the interesting traffic (which will be sent via encrypted VPN tunnel).

  You will need to classify the traffic originating from your end because it's the traffic that will be encrypted, in your ACL it (coming from the other site or customers) it is already encrypted and you'll decripted as soon as he arrive at your end.

  I hope this has been informative.

• 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.

• modem router VPN hardware firewall - config possible?

  We have 2 remote employees having difficulties with their VPN client software turn off/on.  We were preparing to spread the VoIP phones up to them and won't open our internal PBX network.  I would like to make 1 stone 2 strokes by providing a hardware VPN to each employee to establish a gateway 2 IP Sec VPN gateway between their home and the main office.  This should provide a more reliable connection and throughput high, all allowing the VoIP phone to connect through the VPN tunnel, thus keeping our secure internal PBX.  So far so good.  From what I can tell the rv120w, rv220w or cisco asa 5505 would do the trick.  Now the difficulty - I don't want any personal traffic (Netflix streaming, whatever) from home, traveling through the VPN tunnel.  So I would like to allow the employee maintain their own network staff, and within the personal network the hardware VPN device providing a secondary network would use the VPN tunnel.

  It would look like this:

  Web:

  wireless router: (dynamic public IP 192.168.1.x private subnet)

  personal computer

  laptop

  television network, etc.

  hardware VPN device: (192.168.1.1 IP WAN, private subnet 192.168.2.x), IPSec VPN tunnel to the main office (must use internal DNS main office)

  Phone VoIP (192.168.2.1)

  Desktop computer (192.168.2.2)

  Seems simple to me, but concerned about through two NAT.  Looks like this would be preferred for a desktop home configuration that shares a single internet connection.  Found an old Cisco product that was aligned to this specific scenario - the Cisco VPN 3002; but it is the end of life.

  I'm also a bit wary of different routers Cisco RV line poor consumer reviews.  Whereas the Zyxel Zywall USG 20 as an alternative.

  The split of RV120 and RV220W site-to-site VPN tunnel support, so all traffic "cluttered" would remain local for home networks while the VPN traffic that's exactly right.

  You can consider installing one of the routers listed above in areas home to avoid the double-NAT or additional purchases. The VPN device does not practice given that the expense of a gateway to gateway VPN router is fairly inexpensive.

• 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.

• BEFSR81 v3 after upgrade without browser admin access

  After upgrading my BEFSR81 v3 to the latest firmware (2.51.4, build 001 June 13, 2008) I often have problems of access to the Web interface.

  Immediately after a reboot, I can access and manage the router with Firefox or IE without problem.  But then if I do a configuration change the next day all I get is a blank screen after the login prompt.  The only way to solve the problem is to reboot the router.

  He always asks an id of username/password correctly, and if I get the wrong information I'm getting an authorization failed.  But put the correct password just give the empty window.

  I'm tired of running down in the basement of restart the router every time I need to make a change.  Any idea what's going on?

  My router works better, so I'll give my solution here for others.

  During a chat session on 10 April with the support of Linksys, I explained my problem and was told that I can download an older firmware to the following address, then use TFTP to perform the downgrade.  I checked this address still today while writing this message, and I can't get there more:

  Linksys FTP server

  On 10 April, which worked and I managed to download the 2.50.2 firmware which is old enough, but it's the only version I could find on the site recommended.

  The good news is that worked and my router is functional without obvious problems for about two weeks.

  Today I decided to try upgrading the firmware again.  I am disappointed that Linksys has not addressed this problem somehow because others apparently have similar problems with the "current" firmware version  In fact, there is a certain
  confusion on the Linksys BEFSR81 v3.0 support page.

  As of today (April 26, 2009), the download of the firmware for the BEFSR81 page lists the following:

  2008-06-13
  Ver.2.51.1

  (I'm not that these date and numbers because they do match).

  The file of the firmware provided in the link is actually: 2.51.4.4_20081230_code.bin

  Notes the following version history list:

  Firmware Date: June 13,2008
  Current firmware: Version 2.51.1
  Product PartNo: BEFSR81 v3.x

  2.51.4.4 December 30, 2008
  2.51.4.1 Jun 13,2008
  2.51.3 March 2, 2007
  2.51.1 May 5, 2006
  2.50.4 Nov 15, 2004
  2.50.2 May 19, 2004
  Oct 15, 2003 first version 2.45.5

  So, from my own experience and that of others in these forums, version 2.51.4.4 does not work on the BEFSR81 v3.0.

  There are still 2.51.4.1 on the old Linksys support site:

  Linksys support (old)

  It's the version I have installed now, and so far it seems to work.

  I really wish I could find the version 2.51.3 somewhere that it was the most reliable for me.  Unfortunately, I can't find that anywhere.

  Additional information, another user is in these positions:

• 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.

• 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.

• Site to Site VPN working without Crypto Card (ASA 8.2 (1))

  Hi all

  Find a strange situation on our firewall to ASA5540:

  We have a few Site to Site VPN and also activate on the ASA VPN cleint, all are working properly. But finding that a VPN from Site to Site is running without crypto map configuration. Is this possible?

  I tried to erase isa his and claire ipsec his then VPN came once again. Tested too, it's the ping requests to a remote site through the VPN.

  I saw there are config tunnel-group for VPN but saw no card crypto and ACL.

  How is the firewall knows what traffic should be encrypted for this VPN tunnel without crypto card?

  This is the bug?

  Thanks in advance,

  It can be an easy vpn configuration.

  Could you post output config operation remove any sensitive information.  This could help us answer your question more specifically.

• routing of multiple site-2-site VPN gateways

  I have a strange configuration and need help.

  We have and ISP with a 29 network. We have connected the Ethernet transfer to a 2 layer equipment and connected one end to a Calyptix firewall and the other to our Cisco 2811.

  the router has a default route that points to the Calyptix firewall.

  Currently, the router also has a P2P T1 line at the corp office.

  We would like to install a VPN site-to site of this router in the corp office and use P2P as the backup to local traffic, but everything else goes out the ASA.

  I feel like I should be able to configure a tunnel between the two (branch and corp) public IP addresses, but I can't ping the public IP address of Corp. branch because it passes to the firewall (default route).

  What Miss me?

  I have attached a PDF file of the configuration of the network.

  I tried to configure static routes

  IP route 50.199.17.17 255.255.255.255 72.34.95.209

  &

  IP route 72.34.95.210 255.255.255.255 50.199.17.22

  But this does not work, any ideas or suggestions?

  Hi James,

  1. Please check the traffic from 50.199.17.17 to 72.34.95.210 where he's going. Make an itinerary of track of 72.34.95.210 and check if it goes to 210 OR a.211 (capture the firewall), then to 210

  Note: Maybe traffic flow return of 50.199.17.16--> Firewall (72.34.95.211)--> router based on your current configuration (maybe ISP force to go in this direction)

  (2 Please check that you do not receive this route(50.199.17.16/29) P2P T1 somehow by a trace of 72.34.95.210 to 50.199.17.17.

  3. check that you don't have any inbound ACL on both routers.

  Please mark this message as correct if it works.

• Question card crypto for VPN gateway router

  I'm moving my VPN environment at 2811 routers. I move a seller more tomorrow which has two sources who need to connect to each of our IPs, those inside the IPs are NAT had real IPS at the firewall behind the router. I know I'll find out tomorrow, but thought I would see if anyone see a problem with this ACL that is used for the encryption card, is there a problem with multiple sources (50.50.50.1 et.2 in file) connection to the same destinations? The IP addresses in this file are not real output IPs. Thank you.

  If I understand you correctly, no it should not be a problem at all. Each entry in your crypto ACLs card will create a separate IPSEC security association pair and there is no overlap.

  Let me know if I misunderstood your question.

• VPN gateway to gateway RV0XX

  Greetings,

  I have a RV082 and a RV042. I was able to successfully establish a vpn connection from gateway to gateway between the two and I can remotely manage each router through the VPN connection, but I am unable to computers ping from one side of the connection to the other. For example, a computer in the 10.10.1.0 subnet cannot see / ping / communicate with a computer in the 192.168.1.0 subnet.

  Here are the configurations for each. Apart from static IP configurations and VPN configurations, no other changes were made to the routers.

• 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.
