• How to circumvent the "Assistant" secpol.msc and configure State IPsec (esp, spi, enc, auth-trunc) and political (src, dst, in, on, fwd) directly as in the ip-xfrm Linux command?

  Right off the bat, the wizard tells me that I can't use a multicast address, when it is the only destination I am interested in security.  Here is exactly what I want to do - no more, no less (although I can use the mode of transport instead of tunnel at some point):

  #! / bin/bash

  Echo 2 >/proc/sys/net/ipv4/conf/eth0/force_igmp_version

  # NOTE: To avoid the possibility of breaking IGMPv2 snooping, src should ONLY be defined for SHIPPERS, NOT for RECEIVERS!  Otherwise, joins will be compromised by the IPsec encryption and the switch will not detect them.

  Duyen

  Hello Duyen,

  I think I've narrowed the issue. When remote access VPN using RADIUS authentication we must keep in mind that authentication and authorization are included on the same package.

  Depending on your configuration, the ACS is defined as a server RADIUS (Gserver Protocol radius aaa server) and becomes the VPN Tunnel authenticated and 'authorized' on this server group:

  authentication-server-group LOCAL Gserver

  authorization-server-group Gserver

  As noted above, the RADIUS of request/response includes authentication and authorization on the same package. This seems to be a problem of incorrect configuration that we should not set up the 'permission' in the Tunnel of the group.

  Please remove the authorization under the Tunnel of Group:

  No authorization-server-group Gserver

  Please test the connection again and check the logs of the ACS. At this point there are only sucessful newspaper reported on the side of the ACS.

  Is 'Permission-server-group' LDAP permission when authenticating to a LDAP server so to retrieve the attributes of permission on the server. RAY doesn't have the command as explained above.

  I hope this helps.

  Kind regards.

• Configure to integrate Cisco ASA and JOINT

  Hello

  We have Cisco ASA and JOINT, need assistance on the integration of the same thing; Please email me so that I'll share the details of the architecture.

  Thank you best regards &,.

  REDA

  Hi reda,.

  If I correctly your diagram, you do not want to send any traffic from the external switch to the JOINT with a SPAN port and all traffic from your DMZ interfaces with another.

  Is this correct?

  If so, can you tell me why you want to inspect the traffic before it goes through the firewall? As I said in my original answer, we generally advise putting IP addresses after the firewall.

  Not to mention that in your case, I guess that some traffic will be inspected twice so you will need to assign a different virtual sensors to each JOINT internal interfaces to ensure that the same instance does not see the traffic of several times.

  Kind regards

• VTI and crypto card

  Hello

  I wonder if it is possible to have a configuration in IPSEC tunnel, in which one side of the tunnel is configured with static VTI and the traditional second with crypto-map.

  If so, how the configuration on the crypto-Map site should be configured.

  Thank you in advance for an answer.

  Concerning

  Lukas

  Lukasz,

  This config is impractical for several reasons.

  VTI dictates that a "any any" proxy set ID is negotiated. While this works well on a virtual interface, where routing can push traffic to a specific interface, it will make ALL traffic is encrypted on crypto maps side and expect all traffic is encrypted when it is recived (because crypto card is part of ECAS in the Lane exit).

  A more practical approach in the world of Cisco is multi SA DVTI, where a DVTI can put end to any kind of insider tunnel (i.e. allow us DVTI to manage several SAs under a virtual interface) it works very well in some cases.

  You can have DVTI on your end and allow the clients to use almost anything (from ASIT cryptographic maps).
  I'll shoot you as an email at the same time, a bit stuck on something at the moment.

• 2 one-Site VPN Cisco 2801 and with crossing NAT

  Hi guys,.

  I would like to configure two Cisco 2801 using IPSEC/IKE. Both routers are connected to the internet through DSL lines. The DSL line have RFC1918 address side LAN where routers connected to the internet face. I can do NAT on DSL modems.

  Cisco IOS 2801 routers allow to configure site-2-site VPN with NAT crossing?

  Here is a model of physics/IP configuration:

  LAN<->2801 Modem DSL<-Internet->DSL modem<-Priv ip-=""> 2801<-Priv ip-=""><-> LAN

  Thank you

  Gonçalo

  Yes, you're good to go only if one or both of the sites has an IP address which is natted with private IP address statically. The implementation of IPSec on SRI NAT support in most crosses so that shouldn't be a concern

• Router Cisco SSL VPN Configuration

  Hello support.

  A question concerning this scenario.

  One of our clients has currently SSLVPN enabled for remote users and I was wondering if there is anyway to configure a remote Cisco router to connect via IPSEC at this endpoint SSLVPN? the idea is simply to set up the tunnel without requiring changes on my end of customers.

  Thanks in advance.

  Ivan Chacon

  Hello

  IPSEC and SSLVPN are 2 different configurations, there is no way to have a router configured for IPSec and connect to another without changing this end as well.  You can run IPSec and SSLVPN on the same router, however.

  There are a lot of IOS Lan to Lan configuration guides, or if you want the router to act as a client, are looking to make EZVPN.

• Cisco Unity Express Configuration 8.6

  We have a Router (3945) CME with CUE 8.6 8.6 (ISM-SRE-300-K9 Module). I have a few concerns about the installation and configuration of CUE.

  1. Cisco ships CUE 8.6 Application preinstalled on ISM-SRE-300-K9 Module?
  2. What is the initial state of CUE in ISM-SRE-300-K9 Module when he left?
  3. To restore CUE setting factory and download/install CUE from scratch?
  4. OR can I directly give the IP interface addresses and go directly to the CUE - GUI?
  5. As I ordered three languages (Arab Saudi, British and English North American) these language packs are available with in the Module when it was shipped? or do I have to download and install?

• Cisco ISE and Meraki RADIUS

  I am very new to Cisco ISE and Meraki.  I try to get the Radius configuration for wireless authentication.  When I do a test of the Meraki to ISE, it passes.

  When I try to connect from my laptop, I look at the logs of the Radius and it passes; However, it does not connect me to good policy.  I keep hitting the default policy.  I have my Meraki police above the default policy in the strategy defined in article.  I have attached what looks like my strategy game.

  Devices does not really matter. Here is what I see when I create a device group (where you add the access point to this group), and then create the condition:

  networkdevicegroups.PNG

  

  And here is where I create the condition of strategy game and you should be able to select the Meraki access points:

  devicecondition.PNG

  

  This will give you the condition similar to what I posted above. This is perhaps why you aren't hit that is not matching the condition for this game.

• HSRP between Cisco 4321 and Cisco 887VA

  Hi all

  I am looking to install the following and I was wondering if anyone could answer a few questions I have.

  Installation program:

  • A subsidiary, our ISP gives us 20/100 leased line and ADSL circuit use for failover.
  • We plan to connect the line leased to a Cisco 4321 or a G2 Cisco 2921/2951
  • We intend to connect the ADSL circuit to the Cisco 887VA G2
  • We will have a pair of HA of the ASA firewall 5506 x connected routers (be it via a dedicated L2 switch or a VLAN on a switch L3).
  • The LAN is sitting behind the firewall.

  We want to run BGP on both routers (the one that connects to the leased line and ADSL line) and configure them as a pair of HSRP/VRRP, while if the leased line LAN users cannot always access internet and you connect to the main office through a VPN S2S which ends on the firewall. BGP will be used to announce our public subnet to the ISP

  Questions

  1. Can a 4321 and a 887VA form an HSRP/VRRP pair as they are running IOS XE and IOS?
  2. How much RAM and Flash is recommended on each router for BGP?

  Thanks in advance for your time.

  Ranil

  Hello

  Can a 4321 and a 887VA form an HSRP/VRRP pair as they are running IOS XE and IOS?

  This isn't a problem, it will work between two routers

  1. How much RAM and Flash is recommended on each router for BGP?

     Flash is only an isuse to the size of an image, both routers should have enough speace in support of the default image size

     800 s cannot support full BGP table they can not handle cpu or ram and 4321 same with 8 GB of ram can fight a bit with full table, you plan on reducing what is learned inform your ISP regarding prefixes?  route map and prefix filtering?

     the leased line is 100 to download 20 upward, 4321 media and aggregate of 50 - 100mps may need to get the 100mpbs for her performance / request

• Help setting up a laboratory at home using Cisco kit and a blank Superhub

  

  Hello world

  I just started my CCENT class and so I try to create a laboratory that is separate from my LAN House, initially using a blank Superhub and a Cisco 1841 router.  Please keep in mind that I am a beginner, so it may not make sense or be completely illogical...

  The superhub for those who don't know, is a renamed netgear, limit VMDG480.  It's basically a cable modem and router wireless combined.

  The normal daily LAN side of the network was the default installation to receive an IP address via DHCP from the superhub in range 192.168.0.1/24.

  At first, I thought I could put things in preparation for my lab installation, by configuring the LAN subnet using 192.168.0.0 and superhub of/16 mask rank for my 'everyday' network and 192.168.1.0 rank for my "laboratory at home." (Good or bad?...)

  Unfortunately, I'm unable to do so because the superhub only allows the last byte in the mask to be changed, so I changed the mask and it now reads 255.255.255.128, with the idea that I can always have 2 separate networks.

  In the photo above you can see devices on the right side are all directly related to the superhub and continue to work as usual.

  On the left side is where I've implemented a Cisco 1841 router and a laptop computer to test.

  The details of each device are;

  Blank Superhub
  LAN:192.168.0.1
  The DHCP scope: 192.168.0.2 - 192.168.0.126

  Cisco 1841
  Fast Ethernet 0/1: 192.168.0.126
  255.255.255.128

  Fast Ethernet 0/0: 192.168.0.129
  255.255.255.128

  PC2 (mobile wired connected to FE 0/0)
  IP: 192.168.0.200
  255.255.255.128
  Default gateway: 192.168.0.126 (the address IP of Cisco 1841)

  Someone would be kind enough to look at this and tell me where I'm wrong please?

  I thought about pulling the superhub completely, but I am bound to her by my ISP :(

  Hello

  It of a little early in your studies for this :) but implementation of your knees it should work:

  1841 router:

  int fa0/0 (interface connected to the hub)
  IP 192.168.0.126 255.255.255.0
  NAT outside IP
  No tap

  int fa0/1.2
  encapsulaton dot1q 2
  IP 172.16.0.1 255.255.0.0
  IP nat inside
  No tap

  int fa0/1 (interface connected to)
  No tap

  NAT configuration:

  access-list 1 permit 172.16.0.0 0.0.255.255
  IP nat inside source list 1 interface fa0/0 overload

  Add a default route:
  IP route 0.0.0.0 0.0.0.0 192.168.0.1 (so your router knows where to forward DNS queries to 8.8.8.8)

  Connect your 3560 to the second port on the router and configure a trunk on the switch port and add vlan 2:

  int fa0/0 (connected to the 1841 router)
  switch to trunk encapsulation dot1q
  mode trunk switch

  VLAN 2
  name Home_Lab

  Connect your PC to the second switchport and add vlan2:

  int fa0/1
  access mode switch
  access switch vlan 2
  No tap

  Finally, give your PC an address in the subnet of vlan 2:

  IP: 172.16.0.2
  Mask: 255.255.0.0
  Gateway: 172.16.0.1
  DNS: 8.8.8.8

  You should be able to ping the address of the router on the subnet in 172.16.x.x 192.x.x.x. I don't have a Virgin hub to test this, but it worked well with two 1841 routers.

• AnyConnect configuration using IPSec

  I have configured our ASA 8.4 (7) running for the client AnyConnect (using IPSec). It prompted me to create an identity certificate when you run the VPN Wizard, I did. We use AAA to authenticate, so I not create a CA. It must in any case for AnyConnect? When I try to connect from a client AnyConnect prédéployée, I get an error: "untrusted certificates VPN server. If I ignore and choose Connect in any case, the connection fails. What Miss me?

  Thank you

  In addition to VPN IPsec IKEv2, there is a bit of customer service that runs when you first connect. which is used to check the version of the package AnyConnect and distribute changes in the customer profile (and some more obscure things). 'S done it via SSL and that these uses of certificate of the ASA to validate the server. If your client does not trust the certificate, you will get the error.

  You can disable the service the customer by changing the default command:

  Crypto ikev2 activate out of service the customer port 443

  Just read

  Crypto ikev2 allow outside

  The best way is to enable and configure the ASA with an appropriate certificate of trust.
