• GMs in GDOI GET VPN

  I want to know that if a member of the (GM) group can be a member of multiple groups, if yes, a configuration or a link can pl be provided showing the configuration where a GM is configured as a member of several groups/policies.

  Thank you

  M.K.Gupta

   A key server can support multiple groups. A group member can be part of multiple groups.

  The Setup is simple enough, you apply usually different cryptographic cards to different interfaces.

• Key to GET VPN server

  Hi all

  We test the script GET VPN through the MPLS infrastructure using key 2 servers. In one of the key server, we have defined the local precedence than the other key server. The keyservers between them chose the higher priority server key as the main.

  In the configuration of the group members, we have defined key server addresses in the primary and secondary order.

  When unplug us the Server primary key and all the members of this group registers with the secondary key server and when the primary key is back, membership with the secondary key shows. Is there a way as in HSRP to stay ahead on the primary key.

  Second thing is, when unplug us the key server secondary, members who were registered at the recording of shows always server secondary key with this key server regardless of that this key server crashes. Is it a normal thing?

  Kindly help us.

  Thanking you

  Anantha,

  GM presents KS 'Active' in the group as the KS server list that registered the LAST GM with. This does not mean that GM will be re - registering with this first KS should it fail to get one to generate a new key. The GM always starts above him ordered list.

• Administration of the ASA via IPSec VPN

  Recently, I upgraded my ASA5505 8.2.1 7.2 and curiously lost the ability to manage a VPN (via ASDM or SSH) unit. Before the upgrade, I was able to connect via a method without problem through the VPN. Internally, I still have no problem.

  The fault on the ASDM client message when I try to connect to remote is "Impossible to launch the 10.x.x.x:4444 Device Manager." If I look at the output of the console mode of information, I see later that there is a "completed by interception TCP Flow' regarding the conversation between ASA and my system remotely.

  The config lines are (I've got running on 443 webvpn):

  http server enable 4444

  255.x.x.x http inside 10.x.x.x

  http 192.x.x.x outside 255.x.x.x

  The 192 is located the beach DHCP VPN that get VPN clients (and I checked) such that these systems are able to connect to the ASDM or SSH management interface.

  Is there another ACL I need to make this work? Not sure why it worked without problem on 7.2 and as soon as I upgraded to 8.2.1, he stopped, without changing the config (manual).

  Thanks in advance for the help!

  Point VPN network ssh interface inside rather than the outside, should work, while vpn - ssh to the asa inside the ip address of the interface.

  without ssh 192.x.x.x 255.x.x.x outdoors.

  SSH 192.x.x.x 255.x.x.x inside.

• Should I wear to the front through a VPN

  I currently have a Cisco 1905 as my hub router, running v15.1 (4) M4. (192.168.1.0/24)

  This router has a static public IP address on interface GI0/0 and the internal address is enabled GI0/1 and we use NAT for Internet access.

  I have an ASA5505 (v8 (4)) Branch (192.168.12.0/24) connection to the router with EZVPN and the VPN is setup and works as it should.

  I can access the branch out of the hub and vice versa.

  I have a security camera in the branch that I can access through the VPN without problem.

  The problem occurs when I try to access the camera from the internet using port forwarding.

  We have several camera in the Office of hub that we access using via the following command port forwarding

  IP nat inside source static tcp 192.168.1.40 80 40001-stretch SDM_RMAP_1 route map

  It works 100%

  I tried to access the camera in the Office using the command

  IP nat inside source static tcp 192.168.12.40 80 41001-stretch SDM_RMAP_1 route map

  but I can't get through.

  I can see the NAT translation in the branch for the port 41001, but I'm not through.

  Is this possible? should I wear to the front in a VPN tunnel?

  The problems is that the branch office is an Office suite and we rent space. We are not provided a public ip address and I have no control over the router providing an address in the ASA5505.

  Any help would be appreciated thanks

  If you have crypto-cards running and you prefer split tunneling, then I suggest a completely different way to resolve that:

  You can install a small linux box (or Win2012R2 will also do the job) in the main exercise (better would an own DMZ for that) and set up as an agent reverse. This system takes requests and passes them to the cameras.

• RV325 Cisco VPN throughput?

  Dear Sir.

  I intend to buy this VPN router to connect my laptop to the home network via the VPN Ipsec configuartion Office of Mr. I have a few questions to ask.

  First of all, my laptop can see all computers on the network with 100 M/s?

  Second, I used this connection for my software Vray for rendering distributed remotely. This is the main objective. Now, I m using the Asus RT - 66U router built in open VPN service and speed 2 M/s, but the actual data flow for this process is 20 M/s. I wonder if I buy cisco RV325 which can help to solve this problem?

  Thank you

  David

  Hello David,.

  You can find in the RV320/325 Datasheed IPSec VPN throughput is 100 Mbps:

  http://www.Cisco.com/c/en/us/products/collateral/routers/rv325-dual-Giga...

  Please note that the upload speed and download you'll actually are also determined by your ISP, as well as the way which you VPN tunnels will have many assets on the router.

• GET VPN tunnel mode and transport mode multicast

  Hello

  I really don't understand why GET VPN uses a tunnel for packets in multicast mode:

  Examples of a @multicast = 239.0.0.37:

  (1) here a package to GET VPN: | 239.0.0.37 | ESP | 239.0.0.37 | transport layer. Payload: : This way, he uses (two IP headers) IPSec tunnel mode.

  (2) here a package that I imagine to be better: | 239.0.0.37 | ESP | transport layer. Payload: : Mode of transport IPsec, 1 registered IP header = fewer bytes used.

  In both cases, the IP header cannot be secured, cause GET VPN Tunnel using the same multicast IP header (this is why it works so well...)

  I don't understand why Cisco uses model IPsec in tunnel mode to encapsulate packets instead of the mode of transport. I can't find a descent of answer to this question... Maybe my question is not relevant?

  Thanks for your replies.

  Concerning

  Stone,

  I quote DIG it

  It is worth noting that tunnel header preservation seems very similar to IPsec transport mode.
  However, the underlying IPsec mode of operation with GET VPN is IPsec tunnel mode. While
  IPsec transport mode reuses the original IP header and therefore adds less overhead to an IP
  packet (5% for IMIX packets; 1% for 1400-byte packets), IPsec transport mode suffers from
  fragmentation and reassembly limitations when used together with Tunnel Header Preservation
  and must not be used in GET VPN deployments where encrypted or clear packets might require
  fragmentation.
  

  In practice, reassambly concerns and initially odd behaviors with some encryption engines caused the recommendation to be tunnel mode.

  That being said, for large packages (where fresh important generals) overhead costs are minimal. For small packages (voice), the overhead is large, but the packet (after encapsulation) size should not be a problem.

• VPN Throughput on 1721

  I have trying to find max VPN throughput on my 1721 VPN package. I don't finy nothing difinitive. I use the Ethernet interface of the WIC to connect to Congress and other centres, so it is not limited by the line rented in most cases.

  The exact flow of a 860MPC base (1721) Cisco router is based on a number of factors. Encryption/encapsulation type, version of the code, etc.

  3DES IPSec router to router "in the laboratory" with 1400 bytes packets are out 8 MB I think. If your network is not "in the lab" you can expect less (probably much less) than that.

• GET VPN on 6500

  Hello

  I was wondering if anyone has come across information about using a 6500 as a key server in an environment GET VPN?

  Hi Jason,

  The 6500 is not support for GETVPN KS

  Table 2 of the following link describes devices that are able to KS.

• Installation and first run of the FF, I get a box that obviously requires a response, but it contains no words, and does not occur when you click it.

  Installation and first run of the FF, I get a collection box that is displayed for about 5 seconds after the program loads and displays the first screen. It obviously requires a response, but it contains no words. The box doesn't cause any Word show either. the screen takes over and no other button cannot be clicked: I have a hardware failure on FF.

  Empty the gray bar, box, box white, question mark?

  This irritating box was related to an add-on for AOL. In order to remove the extension of the problem, you will probably need to start Firefox in Safe Mode so that it does not work.

  You need to close Firefox anyway, you can, for example:

  • ALT + F4
  • Right click of its mosaic on the taskbar > close all windows
  • (Ctrl + Shift + Esc) Task Manager

  To start Firefox in Safe Mode, hold down the SHIFT key while double-clicking the shortcut.

  A small dialog box should appear. Click on 'Start mode safe' (not update).

  Then you can go to the Add-ons page using either:

  • CTRL + SHIFT + a
  • "3-bar" menu button (or tools) > Add-ons

  In the left column, click Extensions. Then on the right, locate AOL.

  A little luck?

  Have you checked the target line in the properties of the desktop shortcut?

  Start Firefox in Safe Mode to check if one of the extensions (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem.
