• Is - a used the 3602e as a bridgeing only between two networks?

  Is - a used the 3602e as a bridgeing only between two networks? 2504 controller version 7.4.100 I can't ping anything on one side or the other of the network, but I can ping from each access point controller. I have two 1552 setup the same way with no problems. Anyone seen this before?

  Thank you!

  In the case of 3602e as bridge link and you bet the config is a working one, then I would check the antennas if they are properly aligned, if you use a higher gain, a good one would be a necessary in the case of 3602e, I think that Yes.

• How backup VPN configuration between two universities?

  Hello, I am a student of the Greece and I have a graduation project to configure Backup VPN between two universities. Principal of communication made with leased lines. I study a lot, but now that it's time for implementation I have some thoughts:

  -What hardware and software IOS do I need? Cisco 1841 it is ok for A & D routers?

  -Use GRE IPSec transport mode or IPsec Tunnel mode?

  -What will be the failover mechanism for switching traffic lines leased to IP VPN Backup and opposite? A teacher told me something about the Interface Prioritys. I read somewhere that this is done with the such as EIGRP routing protocol. who was right the Professor or the book?  :-D

  -In the same place, they have Firewall and NAT, I need to do any action for this?

  The attached file contains topology I want to implement

  'My' talk site 1

  2 a Central Site

  E communicates with A, but no traffic is to A of E with normal circumstances. Subnet on E access Internet through F, then press D.    VPN will be implemented on the LAN but the specific source E traffic will pass through the Backdoor VPN (I think that the solution to this is ACL on the router). They have no routing protocol in 'my' site A directly connected routers and the default routes.

  How imlement this?

  I think the first thing to do is A to D connectivity

  I will try to do this to tracers package first, but how can ' I imitate the SP network?

  I need help I can get!

  Hi John,.

  In our scenario, given that our main connection is a direct leased line between E and F, so I guess there is no other network between the two routers. In this case we do not need to configure SLA monitoring or any interface a priority. We can simply enter two default routes:

  IP route

  IP route 254

  In this scenario, if the leased line interface goes down, the second default route is used and the traffic should be routed by A router.

  SLA monitoring monitors connection (using the ping tests) by one of the interfaces of the router, and when we are not able to ping from one server (specified in the configuration of the SLA) through the interface, then we change the default track to track traffic through some other interface.

  So, in your scenario, we can monitor the connection between E and F, and when the link goes down, we can change the default route to point a.

  This is useful in the scenario where we have another ISP connection as our primary connection.

  Here is a link on how to configure SLA monitoring on the router:

  http://www.Cisco.com/en/us/docs/iOS/12_4/ip_sla/configuration/guide/hsicmp.html

  After you have configured the SLA followed by using the link above, you can bind it to the default route by using the following command line:

  track road IP / / default main route

  IP route 255 / / default route with a metric of higer that comes into play when the main default route goes down

  In addition, the sample configuration that you give in the doc is almost correct, defined transformation is missing just a hashing algorithm. Here is a link with an example for a tunnel from lan-to-lan between two routers:

• Communication between two network cards on windows 2003

  Hi all

  I need your help.

  I have a machine virtual windows 2003 with two network adapters.

  NIC 1 - external - 192.168.1.101

  Map NETWORK 2 10.10.10.1 - internal -.

  I've configured to operate as a DC and DNS serving 10.10.10.x network.

  DNS is configured to resolve before on 192.168.1.1 as redirector DNS requests.

  I have other machines connected to the 10.10.10.x network.

  They can ping 10.10.10.1, they can ping 192.168.1.101 but not 192.168.1.1

  I want to just be able to talk to 192.168.1.1 and be able to access the internet.

  No firewall between the two.

  Command-line may help, but I would need your help.

• VPN connection between two pix firewall problems

  Hi, trying to create a VPN between the firewall two pix a 501 and a 506e.

  currently on the 506th pdm shows 1 IKE tunnel in the stats, but it displays then return to zero. The two hosts of pix can access the web and ping each other gateways.

  I posted the 506th config but the 501 config is the same.

  outside IP for pix 506th = a.a.a.a

  outside IP for pix 501 = b.b.b.b

  Internet service provider ip of the gateway to 506th = x.x.x.x

  Thank you

  Alex

  Hi Alex

  See the configuration on the other side (PIX501) it will be difficult to solve, you'll need to be sure when it is a phase failure 1 or phase 2.

  Please note between the two PIX IPSec negotiation fails if both of the phases SAs IKE do not match on the peers.

• Question about encryption for a VPN established between two of our sites

  We have two routers Cisco 2951, one at our main location and one at a branch.  An engineer for a local company came and worked all the parameters, including the VPN between the two men.

  For an upcoming exam, the firm wanted to know what kind of security/encryption has been implemented between the two routers.  The engineer is no longer available, so I've went over our configuration files for each of the routers and will have questions about what to tell them (I'll be the first to admit that some of this stuff is over my head).

  I enclose the portions of the configs with "crypto" information he put in place.  If you see something wrong, or need something extra, let me know.

  Thanks in advance!

  That's what you use:

  Phase 1: 3DES, SHA1, PSK, Group2 DH (1024 bits), life time 86400 s

  Phase2: 3DES, SHA1

  Which is today considered legacy crypto, but probably nothing to worry. The crypto-config has always considered that there is "room for improvement"...

• Routing between two network cards

  I have 8 fiber switches that are configured to use a private network for management.

  The subnet is 192.168.8.0/24.

  I have a W2K3 (SERVER A) server with two NICS, a NIC (192.168.8.1) is attached to

  the 192.168.8.0 subnet and the other (192.168.100.14) NETWORK adapter is attached to the subnet 192.168.100.0/24.

  I put up two persistent routes of road between these NICS using the following commands:

  Pei route add 192.168.8.0 mask 255.255.255.0 192.168.100.14

  Pei route add 192.168.100.0 mask 255.255.255.0 192.168.8.1

  I have an other W2K3 server (SERVER B) with a single NETWORK (192.168.100.12) card that must be able

  to connect with the fiber switches via tcp/ip. Packets should be routed to this server.

  On that I put in place a permanent route:

  Pei route add 192.168.8.0 mask 255.255.255.0 192.168.100.14

  Everything works very well.

  (Assumes that the SERVER-A and SERVER B are now turned off)

  I'm trying to reproduce this on my VMware ESX Server 3.5upd3.

  ESX server has two NICS, one attached to each of the subnets. I create a virtual machine to replace SERVER-a

  with the same number of network cards and the same IP addresses.

  I then create routes as follows:

  Pei route add 192.168.8.0 mask 255.255.255.0 192.168.100.14

  Pei route add 192.168.100.0 mask 255.255.255.0 192.168.8.1

  PROBLEM: as soon as I add the second route I can no longer ping any server on the 192.168.100.0 subnet.

  This also causes connections to last very long.

  Do I need to implement routing between network adapters ESX scale to make this work?

  If so maybe want the command look like? If not, what could be my problem?

  Thank you for the helpful answers

  If you want to configure your machine as a router, you will need to notify the router is the next hop.  Now, the next machine break is its own interfaces, which will not work.  And since you are running some sort of routing protocol, provide two solutions to exit the server is not a good idea, because he doesn't know that one to use.  It will use 1 for some and another for some.

  Do what you intend (or I think you intend), you must delete the static routes and choose a default route, which will be your next jump.  This should be another router in your environment.  Then, the other servers that you want to route via ServerA, ServerA interface on this segment would remind you.

  Hope that makes sense.

• Site to Site VPN tunnel between two ASA

  I use the Site Wizard to Site on an ASA 5520, and ASA 5505 of the ADSM. Both are using 8.4 (5). When you create configurations. You follow the wizard configurations with manual what ACL s to allow the traffic of every subnet connected to talk to each other? Or they are automatically generated in the configuration file? Have not been to school yet to understand how to create the CLI VPN tunnels and what to look for.

  Thank you

  Carlos

  Hello

  First, I would like to say that I don't personally use ASDM for the configuration.

  But you should be able to configure all the necessary elements for a connection VPN L2L base through the wizard.

  I guess that typical problems to do so could relate to the lack of configuration NAT exempt or might not choose the setting "Bypass Interface Access List" that would mean you would allow traffic from the remote site in the 'external' ACL of ASA local interface. Like all other traffic coming from behind the 'outer' interface

  If you share format CLI configurations and say what networks must be able to connect via VPN L2L then I could give the required CLI format configurations.

• Between two networks of rooting

  Hi all

  I want to test a network topology that includes 5 pc is connected to the same switch. The problem is that I want to have the first 3 pc with ip 192.168.1.x and the rest 2 with ip 192.168.2.x.

  Is it possible, through Vmware Workstation?

  Thank you in advance.

  Of course it is possible.

  You run 5 images on the same box.

  The only thing you need to do is activate the functionality of routing on the host machine or on any of the virtual machines with 2 cards NIC.

  In case you are referring to 5 virtual machines running on VMware ESX Server you can enable the routing feature by adding two NIC cards.

  You can use any OS and enable routing.

  Kind regards

• Traffic is failed on plain IPSec tunnel between two 892 s

  Have a weird case and you are looking for some suggestions/thougs where to dig because I have exhausted the options.

  Note: I replaced the Networkid real to a mentined below.

  Topology: a classic IPSec VPN tunnel between two 892 s of Cisco, with pre-shared key and no GRE. A 892 (branch_892) has access to the Internet using PPPoE and has three network / VLAN behind it. A VLAN is coordinated to the PPPoE internet access. Access to the other two VLAN - VL92 (100.100.200.0/24) and VL93 (100.100.100.0/24) is performed via the VPN tunnel.

  Second 892 (892_DC) has just one interface - WAN on Gigabit enabled/connected and a static route to the default GW. It doesn't have any defined interal network. If the router is strictly used to send traffic to VL92/VL93 to the domestic 892 via IPSec tunnel.

  Here's the problem: access to VL93 (100.100.100.0/24) works, however for VL92 (100.100.100.0/24) - does not work.

  Devices in VL92 I ping IP address of 892_DC through the VPN tunnel. The 892_DC router I can ping devices in VL92. However, I can't VL92 ping any device beyond the 892_DC and at the same time the packets arriving on 892_DC for VL92 are not sent through the VPN tunnel.

  I took the package trace on 892_DC using capture point/buffer to nathalie caron to VL92 packages and saw that the traffic coming to the 892_DC. I run the nathalie caron even on Branch_892, and there was not a single package.

  So... What's the problem? More interesting, I modified the way left on VL92 access list and still - no packets are sent through the tunnel.

  Any idea? Two routers config are below

• Help! Static route between two router WRT160NL

  Hi all

  I have my internet connection to connect to my main router from Linksys WRT160NL (192.168.1.1) with 192.168.1.x.

  My 2nd Linksys router to connect to the first gateway as well.
  The 2nd router has the ip 192.168.1.100 WAN and it's a local subnet as 192.168.2.x.

  My 192.168.2.x machines can access the internet and connect to all the machines in the network 192.168.1.x.

  However, the 1.x network cannot access the machines on the network of the 2. And because of that, I can't share or print between two networks.

  I try to add static routes on my main router (192.168.1.1) with the road: 192.168.2.0 mask 255.255.255.0 and default gateway 192.168.1.100

  However, the road does not work yet.

  in any case to ensure that the 1.x network able to access the network 2.x and 2.x access 1.x file and print sharing.

  Thanks for your help!

  Gateway of the router does NAT who made the side inaccessible side LAN WAN, unless you configure port forwarding automatic or similar. If she would not make your LAN 192.168.1 would be accessible from the internet. Static routing will not change that.

  You will need to disable NAT (aka switch to router mode) on the second router. You must configure a static route on the main router then. However, most likely your network 192.168.2 * will not have Internet more because the main router will NAT for 192.168.1. * and no 192.168.2. *.

  If possible set up the second router as access point only and run a LAN.

  Hi Alessandro,.

  The access tunnel split list is great!

  If you are NAT on public and private interface that is ip nat inside and ip nat outside etc.

  You must add the command ip nat inside source list 101 interface Dialer0 overload

  +++++++++++++++++++++++++++++++++++++++

  Or you can create a new roadmap

  new route map permit 10

  ACL #match 101

  command: ip nat inside the interface Dialer0 overload route map

• VPN ipsec active on both WAN ports?

  Hi guys, we VPN works on WAN1 and we WAN2 as a failover.  IF WAN1 breaks down, then we can vpn to ip of backup.

  Is it possible to have active VPN on the two networks at the same time?  Then users can choose to use WAN2, if they think that the main connection WAN1 is too slow?

  Thank you

  Hello

  If it's a C2S, then it is not possible according to my knowledge... because the traffic is going to come back with the route by default... option... so it would be impossible in my opinion... If it's a S2S, then you have a static route to do with...

• ASA 5505 - I can't create an IPSEC VPN between two ASA 5505

  Hello

  I have two ASA 5505 with basic license and I'm trying to create a VPN IPSEC using the CLI. Here are the steps I did:

  1 Configure ASA-1 (host name, vlan 1 and vlan 2).

  2. configure a static route

  3. create object network (local and remote)

  4. create the access list

  5. create ikev1 crypto

  6. create tunnel-group

  7 Configure nat

  and I repeat the steps above with the ASA but another change IP.

  Are to correct the above steps?

  Why can I not create an IPSEC VPN between devices?.

  No, you needn't. The ASA configuration is ok. Packet trace proved it. I think it can be a problem on the hosts. Please, check the firewall on the PC and try to put out of service, if it is running.
