• Public interface on VPN 3000

  Hello

  It is as sure to fix the public interface on a VPN 3000 Concentrator on the internet? Or should there be a firewall in front.

  I understand that the public interface is "hardcoded" and only open ports you'd pass firewall anyway, but I just wanted to check with experts to ensure that :-)

  Hi Peter,.

  I don't think there are major problems involving the public interface of VPN 3030 Internet. It is means in reality for public access... it is a little hardened to allow only specific protocols... If you have an ID, you can monitor the traffic on this interface and shun unnecessary connections if necessary... you also have filters on the public interface, which allows you to restrict the traffic...

  set the vpn behind a firewall increases the complexity of your network. You may as well have this behind, but it will be a little complicated.

  I hope this helps... all the best

• LAN-to-LAN tunnel between VPN 3000 and Cisco 1721

  Hello

  I have a current LAN-to-LAN tunnel configuration between VPN 3000 (3.6) and Cisco 1721 (12.2 (11) T).

  When I use the encryption = authentication and Des-56 = ESP\MD5\HMAC-128 for the IPSec Security Association, everything works fine.

  However, I would like to Turn off encryption for some time getting the speed improvements, so I changed

  Encryption = null esp (in 1721) and to "null" in VPN-3000.

  Now the tunnel is setup but I can spend only ICMP traffic. When I pass the traffic UDP\TCP the message below appears the Cisco 1721

  % C1700_EM-1-ERROR: error in packet-rx: pad size error, id 75, hen offset 0

  Has anyone seen this behavior?

  All those put in place an IPSec Tunnel with only the ESP authentication and NO encryption between VPN-3000 and Cisco 1721?

  Thanx------Naman

  Naman,

  Disable you the vpn Accelerator? "no accel crypto engine. Sure that you can't do with a null module vpn.

• VPN 3000 RRI

  Hi guys,.

  I'm working on the creation of a vpn between a vpn 3000 and a

  point of control, the problem I have on the vpn3000 is that if I do not have

  Select "reverse road injection" it won't establish the vpn.

  I thought she might have because the roads of local lan did not exist

  on the vpn 3000, so I added static to match the list of the network, but it

  still wouldn't go out, as soon as I activate the reverse road injection it

  works very well.

  any ideas?

  Thank you

  Adam Baxter.

  Adam,

  Take out the static routes and also injection Road opposite say-able.

  Activate the logs on the hub of gravity 1-13 for IPSEC & IPSECDBG, IKE, AUTH, IKEDBG, AUTHDBG.

  Try to send a ping to the interesting traffic. Capture logs and send them to this post, let me take a look and see if there is a question that jumps.

  See you soon

• Cisco ACS 5.4 and VPN 3000

  Hello

  I'm trying to use CIsco ACS 5.4 for RADIUS authentication for VPN by using VPN concentrator 3000 users.

  I added the VPN 3000 on ACS and added GBA on VPN group with a shared secret authentication server. When I do a test on the authentication server using the local account that I created on ACS it happens as no response was received from the server so that I can see the RAIDUS AAuth in green.

  Any help would be much appreciated.

  Hey,.

  What is the report on GBA?

  "RAIDUS AAuth in green"

• Console Cable - Cisco VPN 3000 Concentrator

  Where can I get a cable from the console to the Cisco VPN 3000 Concentrator? The place I bought the hub of not sent me one with it.

  Thank you

  JP

  JP,

  Console port for the concentrator vpn being complient rs-232, you can buy two female DB9 to RJ45 / adapters, one for the concetrator and one for the PC to use in the COM1 port, then use a regular straight through CAT5 cable, that's the way I do and it is convenient as suppose to use the straight through serial rs-232 cable.

  With regard to the regular cable this hub comes with you can use it.

• L2l IPSec VPN 3000 and PIX 501

  Hello

  I have a remote site that has a broadband internet connection and uses a PIX 501.  We wanted to connect them with our main office using our VPN 3000 via VPN site-to-site.

  I followed the following documentation:

  http://www.Cisco.com/en/us/products/HW/vpndevc/ps2284/products_configuration_example09186a00800949d2.shtml#tshoot

  However the L2L session does not appear on the hub when I check the active sessions.

  The network diagram, as well as the PIX config and the screenshots of the VPN configuration for the IPSec-L2L tunnel is attached.

  Any help or advice are appreciated.

  I just noticed that the PIX firewall, the phase 1 paramateres are not configured. You must configure the same PASE 1 and phase 2 settings on both ends of the tunnel.

  For example, on CVPN 3000, you have configured settings Phase 1 as 3DES, pre-shared key etc... We have the same configuration on the PIX firewall too.

  Here is an example of sample config

• Network VPN 3000 list

  I keep to err msge "mask/area bad ip address/subnet mask/generic id" when you attempt to add a class C network to the list a VPN 3000 Concentrator using the CLI. Here's my entry 192.168.51.0/0.0.0.255. The number and the wildcard mask seem ok. Isn't the right syntax?

• SSL VPN-3000 errors

  I get a "parse error" when you try to manually create an SSL certificate in the web interface of a VPN 3000; has anyone ever seen anything like that?

  Hi Chaplin,

  This is usually caused by the corruption of software certificate, you may need to call the TAC for specific steps to solve this problem.

  Kind regards

• VPN between a PIX and a VPN 3000

  I'm trying to set up a VPN between PIX and a VPN 3000. All configurations are complete, but the tunnel has not been established. On the PIX, to 'see the crypto engine' and ' show isakmp his ' orders, I do not see the tunnel. Of "show ipsec his ' command, I can see the mistakes"#send"continues to increase when I try to connect to the remote network. Here is the copy - paste command:

  Tag crypto map: myvpnmap, local addr. 10.70.24.2

  Obviously, the PIX identifies protected traffic but failed to establish the tunnel. I was wondering what could be the reason for these kind of mistakes? That means them growing '#send errors?

  Thank you very much!

  Sending error mean simply the PIX is grateful to encrypt this traffic, but there is no built tunnel and so it must drop the package.

  you will need to look at why the tunnel is not under construction however, "sending error" are just a byproduct of some other configuration issue. On the PIX, it looks like you would have something like:

  Crypto ip 10.70.24.128 access list allow 255.255.255.128 10.96.0.0 255.224.0.0

  On the 3000 under the L2L section and the Local and remote network, you need the exact opposite of the latter, then it would be:

  / Local network mask = 10.96.0.0/0.31.255.255

  / Remote network mask = 10.70.24.128/0.0.0.127

  If you have something else the tunnel will fail to come. Otherwise, we see that the Cryptography debugs the PIX and the trunk of the 3000 when the tunnel is built.

• VPN 3000 software issue?

  Hi all

  I have a question about the software for the VPN 3000 goes on the side of cisco, the new 4.2.7.I of 3 August 2006, I found last week, and now I found a newer version with vpn3000 - 4.1.7.O - k9.bin on August 15, 2006.

  It's a bit confusing to me.

  can someone explain to me what to use for a VPN Conc 3030 with 128 MB mem?

  Thanks in advance

  Klaus

  What is your server VPN hardware part number if it takes support 3DES, you can use vpn3000 - 4.1.7.O - k9.bin no. otherwise.

• PPTP VPN 3000

  Hello world

  It is possible more make a VPN Tunnel from a single address IP VPN 3000 using the protcol PPTP?

  because what attempt trevaler of my company to connect from the same IP (valid Internet) is not working. for example, when they all are within any society, it is only a valid IP address on the Internet only a VPN tunnel is possible VPN 3000

  I need more than one connection from a single address IP VPN 3000 using the PPTP protcol

  It is possible?

  Thank you

  Yes, it is possible on the VPN3000 himself, however, most of the time the problem is on the network device so that they cross where they are attempting to connect from. Some device/network firewall they pass through does not support several PPTP connections. Will they have for example an ASA firewall, then they will have to turn on PPTP inspection:

  http://www.Cisco.com/en/us/docs/security/ASA/asa80/command/reference/i2.html#wp1721656

  In short, the problem is not on your VPN3000 but on the network where are made the PPTP connections from.

  Hope it's a no-brainer.

• VPN 3000 and wildcard peer IKE

  The order PIX (http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_sw/v_63/cmdref/gl.htm#wp1027312) reference:

  ISAKMP key address

  To configure a preshared authentication key and associate the key with a host name or the IPSec peer address, use the address isakmp key command. Use the address no. isakmp key command to remove a preshared authentication key and its associated IPSec peer address.

  A 0.0.0.0 netmask. may be entered as a wildcard indicating that any peer IPSec with a preshared key valid given is a valid counterpart.

  Question: Is it possible to do the same thing on the VPN 3000? I have a bunch of PIX firewall, they use DSL w / DHCP. I need them to operate in the Mode of Extension of network, but unlike PIX, I can't seem to get the VPN 3000 to accept the '0.0.0.0' as you can do it with PIX. Anyone has any idea if this is possible or another way to achieve the goal? Any ideas would be greatly appreciated.

  Yep, it's possible, even if it's not too obvious how you do :-) The following configuration example shows how do:

  http://www.Cisco.com/en/us/products/HW/vpndevc/ps2284/products_configuration_example09186a00801dd672.shtml

  The key option is the "Default pre-shared key" under the core group.

• The filtering of the VPN 3000 with multiple businesses and internet access?

  Hello

  We have a scenario where we want to up to 6 companies to connect to a concentrator 3000 3002 HW-customers. Companies should be able to have access to the e a few machines at the central site and and at the same time having access to the internet. We will use network extension mode. They cannot use the PIN-tunnel and we want that all internet traffic through the central site.

  Anyone who think that using the 3000 for this "filtering" is a good idea or should I use an external router routing policies?

  I use the 3000 to complete tunnels and parallel with your corporate firewall. Set the default gateway of Tunnel on the 3000 to be inside the IP address of the firewall and add a static route on the 3000 to your internal network, pointing to your next hop router. Add static routes on your firewall for remote VPN network pointing inside the VPN3000 IP address. This way no matter what VPN traffic that is destined for your interior, network will go to your home router and nothing else (Internet traffic), will go to your firewall and get routed Internet.

  As to where you place the filters, you could put them either on the 3000, but personally I do not like the filter - rule in 3000 stuff too. I would put a list of access on your router (who carry static electricity pointing towards) which allows specific remote networks simply get to the individual inside the hosts and nothing else, it's a lot easier to manage.
