IOS router VPN client

Hi all

I have 2 sites connected through a VPN between 2 IOS routers.

I have also some customers switched that need to connect on the inside network via a VPN with one of the routers.

The VPN client software is enough or should I take into account the other components (for example an AAA for Xauth server)?

Someone at - it an example configuration for the router IOS?

Thank you

If you more security, you can use the aaa server:

http://www.cisco.com/warp/public/707/ios_usr_rad.html .

You can also perform local authentication on the router:

  • IOS router VPN Client (easy VPN) IPsec with Anyconnect

    Hello

    I would like to set up my router IOS IPsec VPN Client and connect with any connect.
    Is it possible to configure an IPSec and SSL VPN Client on IOS router? I use for example a 1841.

    It would be perfect to give the user the choice of SSL or IPSec protocol. And the user needs that the Anyconnect Client.

    I think it's possible with a Cisco ASA. But I can also do this with an IOS router?

    Please let me know how if this is possible.

    Also is it true that the IOS routers are not affected to hear bug bleed? SSL VPN and SSL VPN with Anyconnect page is also save?

    http://Tools.Cisco.com/Security/Center/content/CiscoSecurityAdvisory/CIS...

    But I am in any way interested in using IPSec and SSL VPN on a router IOS...

    It's true - CCP does not yet offer the options to configure a VPN IPsec with IKEv2.

    The configuration guide (here) offers detailed advice and includes examples of configuration.

  • 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.

    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

  • RA on IOS router VPN

    Hello Experts,

    Can someone send me the link on how to set up remote access VPN on Cisco IOS routers (authentication of remote users based on user names configured locally on the router itself)?    I found a few links, but they are all authencating by certificate, LDAP users.     I need authentication direct simple remote control-users by using the name of normal user/pass created on the router IOS locally.

    I don't have CA or LDAP server to authenticate remote users.  I just need simple authentication as what Cisco ASA.

    Hi Wade,.

    In addition to this shared Neno, you can check this link to third party which is pretty clear:

  • VPN client with counterpart on secondary ip address on the public interface of the router

    Hello

    On our office LAN, we have a Linux server than it hosting a VPN connection to a remote client.

    Do this to ISAKMP card on our Cisco router port connections to the internal ip address of the Linux host.

    However, we now want to allow our users to establish VPN connections to our local network using the unit of Cisco VPN Client.

    Of course, this would present challenges, as the ISAKMP our router port is mapped through an internal host.

    So, we tried to set up a secondary ip address on the router and VPN clients to connect to that.

    What we see in our newspapers is as follows:

    Phase 1 is very well established, and the VPN Client prompts the user for a user name and password.

    Authentication of the phase 2 starts, but the router says it's is not to receive a proposal of hash of the client.

    185 12:18:06.943 09/03/11 Sev = Info/4 IKE / 0 x 63000014
    RECEIVING< isakmp="" oak="" info="" *(hash,="" notify:no_proposal_chosen)="" from="">

    (in this case, where x.x.x.x is the secondary ip address on the public interface)

    After that, the Phase 1 SA is removed and the connection fails.

    My understanding is that the Phase 2 negotiation takes place with the ip address assigned to the client in Phase 1, which suggests that the problem occurs because the client communicates with the main on the interface ip address, and no secondary ip address.

    When remove us the mapping of port isakmp and the VPN client to connect to the primary ip address, everything works fine.

    Question:

    It is possible to establish 2 router VPN Client uses a secondary ip address?

    If not, is there some way I can implement the port mapping so that it occurs, the connection comes from a specific ip address?

    Garreth

    Should be supported on IOS.

    The command is crypto ctcp port...

  • VPN Client TCP connection to router IOS

    Hello

    I try to get a VPN client to connect via TCP to a router. I currently have the router put in place (and work) in using a VPN - UDP. Unfortunately one of the sites I visit will not allow VPN traffic outside of their firewall. I have searched all over the site of Cisco and can't find any information on the IOS configuration to accept TCP - VPN connections. I would like to change the TCP port 80, so my VPN traffic looks like just standard internet browsing my client firewall. Any links/pointer would be greatly appreciated.

    Thanks in advance!

  • 6500 IOS router Cisco VPN Client using DHCP no Pool of IP

    Hey guys,.

    I have a little trouble trying to get my vpn client to use a dhcp server rather than the pool of intellectual property.  When I use the command IP pool everything works fine, but when I use the dhcp command I get an error on the client-side saying that no address private IP was affected by the peer.

    Here is my config.

    connection of AAA VPNCLIENT_AUTHEN group local RADIUS authentication

    local VPNCLIENT_AUTHOR AAA authorization network

    Configuration group customer isakmp crypto VPNCLIENT_GROUP

    I can see the dhcp request and offer on my dhcp server but nothing is for the customer.  When I use a pool I ping the dhcp server, which makes me think the roads are okay.  Anyone has any ideas.

    You need the giaddr in an EasyVPN server configuration.  Try adding looping to your switch and test it again.  If you use an iVRF, make sure that the closure is in the VRF and the interface to the server.

  • Routing problem between the VPN Client and the router's Ethernet device

    Hello

    I have a Cisco 1721 in a test environment.

    A net 172.16.0.0/19 simulates the Internet and a net 192.168.1.0/24 simulates the net, the VPN tunnel must go to (intranet).

    The net 172.16.0.0 depends on the router 0 FastEthernet, Intranet (VPN) hangs on Ethernet 0.

    The configuration was inspired form the sample Configuration

    "Configuring the Client VPN Cisco 3.x for Windows to IOS using Local extended authentication"

    and the output of the ConfigMaker configuration.

    Authentication and logon works. Client receives an IP address from the pool. But there's a routing problem

    side of routers. Ping client-side - do not work (the VPN client statistics that count encrypt them packets, but not to decrypt).

    Ping the router works too, but decrypt and encrypt customer statistics in VPN packets count progressive

    (customer has a correct route and return ICMP packets to the router).

    The question now is:

    How to route packets between the Tunnel and an Ethernet device (Ethernet 0)?

    conf of the router is attached - hope that's not too...

    Thanks & cordially

    Thomas Schmidt

    Thomas,

    Can't wait to show something that might be there, but I don't see here. You do not have the card encryption applied to one of the interfaces, perhaps it was not copied. Assuming your description you do it, or should it be, applied to the fa0 and you are connected. Try how you ping? Since the router or a device located on E0? If you ping the router, you will need to do an extended ping of E0 to the ip address of the client has been assigned. If your just ping the router without the extension, you will get sales and decrypts that you declare on the client. Have you tried to ping from the client to interface E0? Your default route on the router is pointing to fa0? You have a next hop to affect? You have several NIC on the client pc? Turn off your other network cards to check that you don't have a problem with routing on the client if you have more than one.

  • IOS router with several groups of VPN

    Similar to a discussion, I read with a PIX firewall, I need to set up multiple VPN groups on IOS-based router to support different levels of security. For example, a VPN "GUESTS" group would only have access to 1 server, while the VPN "ADMIN" group would have access to the entire network.

    With a PIX firewall, you can simply specify additional group names (for example "group1 vpngroup',"vpngroup group2"and so on). However, I have not been able to find how do with IOS-based router (Cisco 831 12.3 (4) T) running.

    For example, I have these dynamic groups of VPN:

    the crypto isakmp client configuration group of GUESTS

    password1 keys

    DNS 10.1.1.1

    swimming POOL1-IP pool

    Configuration group customer crypto isakmp ADMIN

    key password2

    DNS 10.1.1.1

    POOL2-IP pool

    ! - Users get authenticated to a RADIUS server

    list of card crypto CRYPTOMAP customer VPN-USER authentication

    ! - The problem is that line taken out. "I can only specify an allow list (a group name) for this encryption card!)

    card crypto CRYPTOMAP ADMIN isakmp authorization list

    I did research on this site, Google, usenet and ORC and have not found what I'm looking for. Any ideas?

    Thank you.

    Command 'isakmp authorization list' you do it reference does not refer to the VPN group, it refers to a whitelist of AAA name which States that the groups are configured locally. Change to the following:

    AAA authorization groupauthor LAN

    card crypto isakmp authorization list groupauthor CRYPTOMAP

    The "groupauthor" is just a label that matches the encryption to the aaa command. Your clients VPN will be accompanied to a specific group depends on what group name, they set up in their VPN client.

    See http://www.cisco.com/en/US/tech/tk583/tk372/technologies_configuration_example09186a0080095106.shtml for details, it's a HW 3002 client to a router but the router config is exactly the same thing.

    I would be grateful any sort of kelp.

    Thank you

    You must make sure that your internal traffic goes to the VPN client is NOT be NATT would be.

    You need to re - write acl 102 to something like: -.

    access-list 102 deny ip 192.168.4.0 0.0.0.255 192.168.4.0 0.0.0.255
