• VPN3005 and GRE as interesting traffic (in tunnel)

  Hello

  is it possible to qualify the GRE or interesting traffic IPinIP tunnel traffic

  (in the Tunnel LAN2LAN) on a VPN3005.

  On router or PIX simply define you access-list with gre or IP, how

  can you do that on a hub if possible?

  Thanks in advance,

  Kind regards

  Stefan

  Hello

  Just set the Lists(based on interesting traffic) network and hub crypt GRE traffic as IP or ICMP protocol, so no specific configuration is necessary.

  Thank you

• RVL200 IPSEC: run together or some data traffic by tunnel, possible?

  Is it possible to run all the / some data traffic via an ipsec connection in tunnel using the RVL200?

  I have managed to connect routers ipsec RVL200 and RV042 and are able to connect to servers/computers behind it.

  Now I want to run some or all traffic through the ipsec tunnel for computers that are on the 192.168.1.0 network RVL200 subnet.

  Main office - router RV042 - 10.200.62.1

  -Router RVL200 - 192.168.1.1 remote desktop

  I am using the Advanced Routing option to add static routes, but I'm not 100% sure if I am setting up roads properly.

  To give an example of routing queries DNS for HOTMAIL.COM [65.55.72.183]:

  Destination IP - 65.55.0.0

  SM - 255.255.0.0

  GW - 10.200.62.1

  Hop - 1

  LAN - interface

  For some reason any that doesn't seem to work. I also tried to use the setting of the WAN interface and tested - it does not work.

  Is this possible? If someone has tried to do that, I'd be very interested to know how to configure it.

  See you soon.

  Linksys RVL200 or RV042 does not support the split DNS to the IPsec tunnel, which seems to be what you need. You might consider to upgrade the routers for the Cisco Small Business RV0xx routers that do not support DNS split on IPsec.

• NAT traffic on tunneling IPSec (ISR)

  Hello.

  I assumed that I have configure IPSec tunnel between a kind of 1811 and some checkpoint firewall. The IPSec part isen t that big of a deal, but system on the absence of "Side CheckPoint" traffic manager if the tunnel must be from a public IP address and the only source of IP address.

  So, let's say that my ISP gave me 10.10.1.1 - 10.10.1.5, our clients Interior have an IP address of 192.168.10.0/24 range and the remote application in the site "Checkpoint" is the IP address of 172.16.1.10. The result should be:

  IPSec tunnel is created by using the IP address 10.10.1.1 .

  Traffic of 192.168.1.0/24 customers should access the application to the address 172.16.1.10 using as a source above the IPSec tunnel address 10.10.1.2 .

  Is this possible? I guess that would mean I have NAT traffic goes, however, the IPSec tunnel, but I'm unable to get this to work. I googled all day long looking for something similar.

  Anyone who could enlighten us? Any ideas appreciated.

  Sheers!

  Yes, it is possible.  That you should get what you need.  Let us know if it works or not.

• Restricting traffic from site to site

  Hello world

  I have a small question (I hope): what is the best way to limit certain protocols to pass through a tunnel from site to site? Must I change ACL that is assigned to the card encryption or should I create a new ACL and assign it to the interface?

  Thanks in advance,

  Ronald

  Better to use an acl entry to the filter.

  The crypto acl change will do the work of restriction, but can change its ipsec info. Also good with, must change at both ends of the IPSec site.

  config reference.

• Restricting traffic through a VPN IPsec

  I have a lan-to-lan IPsec VPN (PIX501) work, but I would like to limit access to LAN A LAN B I tried to use the command 'no permit-ipsec sysopt connection' with a few changes in the ACCESS LIST bound to the external interface. I did not work. Donkey help would be welcome (doc, experience, etc.).

• How to apply internet traffic in VPN tunnel users

  Hello

  Perhaps it is a simple matter to most of you, but it confuses me right now.

  Here's my situation:

  home - internet - ASA 5510 users - CORP LAN

  We have remote Ipsec VPN and anyconnect VPN, I think that the solution must work on two of them.

  My question is: "how to apply internet traffic user home to the VPN tunnel?

  We have "split tunnel" to only"'interesting traffic' VPN tunnel access LAN CORP.

  but now I need apply all traffic (internet + CORP LAN) user through VPN tunnel passes.

  so far, I did what I know:

  1. remove the "split tunnle" group policy

  2. the address in "remote user VPN address pool" are perhaps NAT/PAT travers ASA5510

  but I don't get why it doesn't work.

  all suggestions are appreciate!

  Thank you!

  A few things to configure:

  (1) Split tunnel policy to be passed under split in tunnelall tunnel

  (2) configure NAT on the external interface to PAT to the same global address.

  (3) configure "allowed same-security-traffic intra-interface" so that the tunnel VPN for Internet traffic can make a u-turn.

  Please share the current configuration if the foregoing still does not solve the problem. Thank you.

• Tunnel traffic inside IPSEC tunnel

  Hello world

  Site has a Site B through ASA IP Sec Tunnel.

  Now turn on Site a GRE tunnel and the tunnel destination is happening inside the IPSEC tunnel.

  In other words, IPSEC tunnel between 2 sites also leads the GRE Tunnel traffic.

  Who's in charge, I can run on ASA whether IPSEC is transport traffic of the GRE tunnel or

  Which line in config ASA will tell me that this IPSEC also conducts traffic GRE tunnel?

  Thank you

  MAhesh

  Hello

  I think that you will probably see GRE in the ASA connection table when the connection is in use.

  You can try the command

  Show conn | Volition Inc.

  And see if this produceses matter what exit.

  Can you possibly provide "interface Tunnelx" configurations and if its using other interfaces such as 'tunnel source' and 'destination tunnel' then their configurations also.

• Cisco's ASA IPsec tunnel disconnects after a while

  Hi all

  I've set up an IPsec tunnel between sonicwall pro road and cisco ASA 5510. The well established tunnel and two subnets can access each other.

  I then added a static route to a public ip address on the sonicwall ipsec policy, so that all traffic to this ip address will go through the IPsec tunnel. It also works very well.

  But the problem is aftre tunnel Ipsec sometimes breaks down, and then I need to renegotiate the ipsec on sonicwall to restore the tunnel.

  This happens twice a day. I'm whther fear that this behavior is because of problems with config. I'm pasting my ASA running Setup here. Plese give some advice.

  I guess you have typo in the configuration of the ASA?

  L2L 192.168.5.0 ip extended access-list allow 255.255.255.0 192.168.10.0 255.255.255.0
  list access extended extended permitted host ip voip pubic ip 192.168.10.0 255.255.255.0

  Can you confirm that you have configured instead the following:

  access-list l2l extended permitted host ip voip pubic ip 192.168.10.0 255.255.255.0

  Moreover, even if the crypto map tag says easyvpn; peer address is correct to point 1.1.1.2

  In addition, don't know why you have the following configuration (but if it is not necessary I suggest to be removed and 'clear xlate' after the withdrawal):

  NAT (outside) 1 192.168.10.0 255.255.255.0

  Finally, pls turn off keepalive to SonicWall.

  If the foregoing still don't resolve the issue, can you try to remove the card dynamic encryption of the ASA (no map mymap 30000-isakmp ipsec crypto dynamic easyvpn), release the tunnel and try to open the tunnel between the ASA and SonicWall and take the exit of "show the isa cry his ' and ' show cry ipsec his» I'm curious to see why he is always referred to the easyvpn crypto map. When you remove the dynamic encryption card, dynamic vpn lan-to-lan of remote access client does not work.

• MPLS TE tunnel broadband bandwidth and ip rsvp bandwidth

  I have a few questions about how to reserve bandwidth in MPLS TE environment.

  1. we need IP RSVP bandwidth in any concern in MPLS TE environment interface, right?

  2. What is the purpose of ip rsvp bandwidth?

  3 tunnel MPLS traffic engineering connection XXX, the define command band bandwidth flow initiated by head, if sending more than XXX flow, how it works? Drop excessive packet in the stream?

  Any point is welcome! Thank you!

  Hello

  (A1) to the right.

  A2) with the "ip rsvp bandwidth" it indicates how much bandwidth on an interface can be booked by MPLS TE tunnels.

  A3) characteristic misuderstood most probably is MPLS TE. It is a pure function of the control plan. So, there's comparison of reserved bandwidth compared to actual bandwidth used or nocheck.

  You can configure an MPLS TE tunnel with 1 Kbps ("mpls traffic engineering tunnel 1") and send 10 Gbps on the way and NONE will be given.

  Where there is an interface in the path, that is supported, then packets will be handled independently having a tag to tunnel or not.

  You might ask: what the point of MPLS TE, then if I have can´t give guarantees of bandwidth with it? Answer: MPLS allows YOU a selection more complex and controllable path in MPLS environment. In addition features such as Fast ReRoute (FRR) are interesting.

  I hope this helps! Please note all messages.

• Configuration of Site VPN connection to another via GRE Tunnels

  I am trying to connect VPN site to site on the internet using GRE tunnels. I am able to reach from a WAN interface to another. But I am not able to get the ISAKMP and IPSec to work. Below the configuration and a simplified below flowchart. In the scenario below, I am also running BGP between these routers. The BGP neighbor-ships are trained through the tunnels. But I want traffic between tunnels to encrypt. IPsec and ISAKMP not running BGP routes and other traffic is not encrypted.

  This is why I would like to know what could the reason for this.

• Default gateway of ASA 5520 8.4 (3) tunnel and different subnets

  Hello

  I fight on a problem for more than 2 weeks despite various searches.

  We have a Cisco router, then a 8.4 (3) ASA 5520.

  The ASA's private interface is connected to a switch and now connected to an interface of the router.

  The private interface is as follows: 129.88.63.253 255.255.248.0 (/ 21) =>

  It's in the 129.88.56.0/21 subnet

  Here is the part of the router configuration, that we are interested in:

  !

  interface Vlan32

  address IP 129.88.63.254 255.255.248.0 (it's the tunnel default gateway configured on the SAA - 129.88.56.0/21 subnet)

  IP 129.88.71.254 255.255.255.0 secondary

  IP 129.88.75.254 255.255.252.0 secondary

  IP access-group CVPN-since - 129.88.56 in

  IP access-group CVPN-to - out 129.88.56

  Check IP unicast accessible source - via rx allow - by default

  no ip redirection

  MLS-rp ip

  !

  On the SAA, there is a default route for traffic in tunnel mode:

  private road 0.0.0.0 0.0.0.0 129.88.63.254 in tunnel

  As you can see, it is on the same subnet as the main Vlan32 of interface IP address on the router.

  The scenario is as follows:

  -We can connect to the VPN with the appropriate alias (LDAP connection), then we get an IP address in the range (this is a local pool ASA)

  -the pool is: 129.88.71.0/24

  - but, once we are connected, we cannot do anything, because it looks like we have no access to the network

  My thoughts:

  For the moment, we give (for the alias/connection profile above based on the LDAP authentication)

  an IP address from a local pool of ASA (129.88.71.1 to 129.88.71.253). But this IP address is not on the same subnet as the

  tunnel default gateway (129.88.63.254).

  For example, if we give an IP address in the subnet 129.88.56.0/21 everything works perfectly.

  However, this IP address is still on the same subnet as one of the secondary IP address of the Vlan32 interface on the router:

  IP 129.88.71.254 255.255.255.0 secondary

  The strange problem is that this configuration has worked for a few days until we reboot the ASA, and now it's over.

  Currently, the configuration on the SAA is the same before the reboot.

  You have any ideas to make this type of configuration really works (multiple subnets but default gateway a single tunnel, which is the only way)

  'access' resources on the network)?

  Given the following...

  -We can only set one and only one tunnel gateway

  -We are unable to extend the 129.88.63.254 ' 255.255.248.0 "subnet

  -the problem is not the ACL (tested with and without and they are OK, they let the traffic of the pools above)

  Thank you!

  Here's an idea. If the secondary IP address is configured on the router just to be on the same subnet as the clients, it is not necessary. It is best to simply set a route in the score of the router

  129.88.71.0/24 to the private firewall interface (route ip 129.88.71.0 255.255.255.0 129.88.63.253). It's basically the difference between data is sent right to the firewall (good) versus the firewall with proxy-arp answer an arp broadcast (not as good).

  May or may not solve the problem, but it's a cleaner configuration.

• Maximum traffic for a vmxnet3

  Assuming that there are no bottlenecks elsewhere, what is maximum penetration network traffic that a unique vmxnet3 adapter on a virtual machine can receive network?  It is 10 Gbit/s (gigabytes per second) or 10 Gbps (GigaBITS per second)

  Thank you!

  In theory and in the physical world, the maximum data rate would be 10 Gigabit/s, since vmxnet3 emulates a 10GBASE-T physical link.

  This flow is governed by physical limitations and traffic on the wire of the standard, but these do not apply in a purely virtual configuration (vSwitch and port group 2 virtual on the same host and same computers).

  Invited on the same host and vSwitch and port group are able to exceed beyond 10 Gbit/s. I know, we could think that for example the e1000, which has a link from 1 Gbps to the guest, is limited to 1 GB/s maximum. or vmxnet3 is limited to a maximum of 10 Gbps. But this isn't the case. They can easily exceed their "speed of the virtual link. Test it with a tool of network throughput as iperf a see for yourself.

  This is because only the true physically imposed restrictions do not apply in a virtualized environment between two virtual machines on the same host/port signalling group. Operating systems don't artificially restrict traffic to match the speed of the agreed line unless it is physically required.

  To give you an example, I am able to reach 25 + Gbps between 2 virtual Linux machines with a single on the same host/network vmxnet3 vNIC

  For reference, I am able to get 25 + Gbps with the test tool of network throughput iperf between two virtual Linux machines with a vNIC vmxnet3 unique on the same host/port group. (Yes, 25Gbps. Even if a vmxnet3 emule link 10 Gbps, throughput is not artificially capped without physical limitation of signal).

  Once you get to the external communication outside a host then you are limited by your physical host of ESXi links limitations.

• LRT214 VLAN and site to site vpn

  Hello everyone, I am a bit new to the network of this aspect and was looking for some advice.  I am looking for several routers LRT214 to configure VPN site to site to our main office at 4 locations.  There are 2 VLANS and subnets - one for the network secure (vlan native 1) and one for comments wireless (vlan 2).  It is very good and works well for lan segregation locally.

  IPSEC tunnels do not pass the tags vlan, my question because I will be able to restrict traffic through the vpn tunnel to vlan 1 and deny traffic to vlan 2?

  It appears in the documentation that VPN traffic can be limited by IP address or the local subnet.  My concern is that if there is no way to bind or bridge to the VLAN selected, an adjustable static IP address on a device on the vlan 2 were part of the traffic permitted (vlan 1 range), and therefore cross the tunnel for devices vlan 1 on remote sites.

  Thanks for any input you can offer.

  Hi, seedtech. The VLAN used for the VPN is the default VLAN. So if a tunnel is created, it will cross through the default VLAN.

• RV220W works only with the PPTP server on one VLAN only

  Hello

  I have a RV220W (firmware 1.0.3.5) but I can't seem to work with the PPTP server on one VLAN only.

  My default VLAN is in 192.168.1.1/24.

  I created a VLAN ID 10 in 192.168.50.1/24 inter - vlan routing: disabled and device management: disabled.

  (Menu network > LAN > belonging to a VLAN and multiple VIRTUAL local network subnets).

  Then I configured a PPTP server on the IP 192.168.50.200 to 192.168.50.210 range.

  Finally, I created my user.

  (Menu VPN > IPSEC > VPN users).

  The PPTP tunnel is at work, but on all of my local network and not only the VLAN ID 10.

  Any idea? ...

  This seems to be a limitation of the firmware 1.0.3.5. Firmware 1.0.4.x will support the rules on access inter - VLAN, which I hope, can be used to restrict traffic VLAN by default your VLAN ID 10.
