VPN gateway with the traffic filtering

• PIX VPN Basics - what the traffic is encrypted.

  I understood that the CRYPTO card MATCH ADDRESS linked to the ACL command identifies the traffic is encrypted, however we have a new client with and VPN configuration operational existing that doesn't have the ADDRESS MATCH viz argument:

  Crypto ipsec transform-set esp - esp-md5-hmac RIGHT

  Crypto dynamic-map cisco 30 transform-set RIGHT

  dynamic MyName 30-isakmp ipsec crypto map Cisco

  MyName outside crypto map interface

  Can someone give me an idea of how this works please? The system is a PIX515E running 6.1. (1).

  The dynamic-map encryption is part of the easy VPN setup.

  Read the description of the dynamic-map command encryption of the order below.

• ASA L2L VPN UP with incoming traffic

  Hello

  I need help with this one, I have two identical VPN tunnel with two different customers who need access to one of our internal server, one of them (customer) works well, but the other (CustomerB) I can only see traffic from the remote peer (ok, RX but no TX).

  Hello

  It seems that the ASA is not Encrypting traffic to the second peer (However there is no problem of routing).

  I saw this 7.x code behaviors not on code 8.x

  However you can do a test?

  You can change the order of cryptographic cards?

  card crypto outside_map 1 match address outside_cryptomap

  peer set card crypto outside_map 1 160.160.143.4

  map outside_map 1 set of transformation-ESP-3DES-MD5 crypto

  card crypto outside_map 3 match address outside_1_cryptomap

  card crypto outside_map 3 set pfs

  peer set card crypto outside_map 3 200.200.200.200

  card crypto outside_map 3 game of transformation-ESP-3DES-SHA

  I just want to see if by setting the peer nonworking time to be the first, it works...

  I know it should work the way you have it, I just want to see if this is the same behavior I've seen.

  Thank you.

• Clientless Webvpn with Citrix traffic filtering

  Hello

  I use an ASA 8.2.2 configured with webvpn without client.

  Since there are several different groups of users, and connection profiles configured, I want to make sure that only certain users have access to certain services. That as I have it configured webtype ACL. It works very well for an associated http or https traffic to the internal server, but it does not work for traffic to the Web interface for citrix citrix server.

  That's how part of my config is looking like:

  ...

  Group Policy X attributes
  VPN-tunnel-Protocol webvpn
  group-lock value X
  WebVPN
  filter value X

  ....

  access-list X webtype allow url http://x.y/* default log
  ...

  Citrix group policy attributes

  VPN-tunnel-Protocol webvpn
  group-lock value Citrix

  WebVPN
  value of filter Citrix

  ...

  access Citrix webtype list allow url https://citrix.local/* default log
  WebType Citrix Access-list allowed citrix url: / / * default log
  WebType Citrix Access-list allowed Citrix url: / / * default log
  access Citrix webtype list allow url https://citrix/* default log
  access Citrix webtype list allow url http://10.1.2.3/* default log
  access Citrix webtype list allow url https://10.2.3.4/* default log
  access list Citrix webtype allow newspapers http://* of the url default
  access list Citrix webtype allow newspapers https://* of the url default
  access Citrix webtype allowed url list any fault of newspaper

  If I'm troubleshooting using the log, I see only permits and no. denies! Also if I look at the number of accesses. But as soon as the channel of Citrix from the Client to the Citrix in HTTPS server is started, it fails if the webtype acl is active (even with the permit of any url at the end!). If I delete it, it works great!

  rastest # sh Citrix access-li

  access list-Citrix; 9 items
  Citrix access list line 1 webtype allow url https://citrix.local/* log by default (hitcnt = 281)
  Citrix access list line 2 allowed webtype citrix url: / / * open a session by default (hitcnt = 0)
  Citrix access list line 3 permitted webtype Citrix url: / / * open a session by default (hitcnt = 0)
  Citrix access list line 4 webtype allow url https://citrix/* log by default (hitcnt = 0)
  Citrix access list line 5 webtype allow url http://10.1.2.3/* log by default (hitcnt = 0)
  Citrix access list line 6 webtype allow url https://10.2.3.4/* log by default (hitcnt = 0)
  Citrix Online access list 7 webtype allow by default of newspapers http://* in the url (hitcnt = 0)
  Citrix Online access list 8 webtype allow by default of newspapers https://* of the url (hitcnt = 14)
  Citrix access list line 9 webtype allow url no matter what failure to log (hitcnt = 0)

  Any idea, advice?

  Thanks for your help!

  Marco

  Hello

  do you still need help with that? If so, could you please try adding a line to the ACL as follows:

  Citrix webtype permitted tcp access list failure to log

  and see if that makes a difference?

• Site to Site VPN, endpoint of the traffic on the loopback and ping down alternative packages

  Hi team,

  This is my first discussion. Today, I came across a new senario where in I was able to establish the tunnel vpn site-to-site between two sites. To my amazement, I am able to successfully ping to the router (Site A) to the server without drops keeping source as fa 0/1 (172.25.170.1) However, LAN segment (host) alternate packages are declining while reaching the server. Please find the picture below:

  

  R2 - is ISP

  We are required to use private segment WAN ip addresses so we have no choice other than to keep the public ip address on the loopback. To create the site to site, I asked the card encryption on the fa outside interface 0/0 with ip 1.1.1.1. Then I used the command cypto card loopback 1 mount the tunnel and work address local VPN. I then set a route on the Site1 for fa of government local traffic 0/0 to insert the interesting traffice enter the map encryption.

  Now everything works well to router server however I get replacement ping drops (50% success). I am not able to solve this problem. The result above is both real and gns.

  Help, please

  Think it's a bug in IOS, disable IP CEF, hen now this works, but it is only a workaround to make it work for real IOS update.

• Have P6860FX gateway with the camera, but cant fint any to actavate it nothing in the programs etc.

  I see nothing installed on starting camera etc.

  Hello

  If below does not work you need to involve support technique Gateway and check with their online
  documentation and forums (if any).

  You will probably need to reload the drivers of the device and any camera control software.

  Login as an administrator.

  Double-click Control Panel / Device Manager - Imaging - writing down of the brand and model of camera.
  on this subject and on the tab of the driver is version. Now, click on update drivers (who are unable to do anything as MS
  is far behind the pilots of certification). RIGHT click on the camera - UNINSTALL - REBOOT - it
  will update the driver stack.

  Now, go to the system manufacturer's website and download the latest driver for the camera and the other related camera
  software (if not more recent get the same).

  Download - SAVE - go to them and RIGHT CLICK - RUN AS ADMIN - reboot after each driver.

  Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

• Having a problem with the new filters to 11 items

  I got elements 11 for a while, but today I tried to use the comic, graphic novel and filters the pen and ink, and when he tries to show the elements of the image hangs. How can I make it work again?

  So, that's the problem.

  What version of mac os x you have updated since?

  These filters will cause pse 11 crashing on mac os x 10.9 Mavericks and mac os x 10.10 Yosemite and as far as I know, adobe has never offered a solution except at the level to 12 PES or PES 13, which do not have this problem.

• Cannot ping the default gateway with Centrino Advanced-N 6235 on XPS 12 but CAN connect to the Internet

  I have a XPS 12 with an Intel Centrino Advanced-N 6235 wireless card.  I can't ping the default gateway with the wireless card.  When I use a USB network adapter, I can ping the default gateway for the wired connection.  I can connect to the Internet and the internal network with the wireless card and can ping other computers on the network.  I am trying to run a program to connect wireless to a projector.  I have two different programs for the two different projectors.  I can connect by cable but not wireless.  I think that the problem is anything that does not make me a ping of the default gateway or something on the wireless card.  I have a 10 latitude with a Broadcom wireless card that is connected to the same access point and can ping the default gateway and can connect wirelessly to two projectors.  They all have two windows 8 Pro.

  I downloaded the new drivers from Dell, uninstalled, reinstalled, tried to update Windows install the drivers, all with no success. Any ideas?

  The solution of the problem by chance.  I was connected to the computer with a different network than what has been used to authenticate user account on the wireless.  When I switched the user account for the user account that was logged on to the computer was the same who authenticate to the wireless, it worked.  Go figure!

• ASA: S2S Tunnel stops with higher traffic

  Hello

  I have no idea where I have to start solving our problem:

  Site A: ASA 5520/9.2 (4) 5 ~ 20 IPsec tunnels

  Site b: ASA 5505/9.2 (4) 5

  When I do a SSH (or HTTP or any other TCP) session from Site A to any Linux on Site B server, I can connect, but when I do something as a "dmesg" or long "ls - al", the session hooked after 10 to 20 lines. Also HTTP sessions (as a site to set up a printer), smaller Web sites are okay (but slow), more big sites stops with a browser timeout.

  This only happens on one site, all other sites work very well (which have the same config, same OS ASA).

  Just to test, I opened the ssh port to the external IP address on the external interface and it works very well, as well as with the traffic through the tunnel going something wrong.

  Any idea, where do I start debugging?

  Gruss ivo

  PS: How is stupid cloudflare, they check this text and do not allow to write the ls command linux less al, but ls space space space less al works!

  You can twist on the SAA mss using this doc and empty the outside df bit as well. Follow the steps described in the section "VPN encryption error."

  Crypto ipsec df - bit clear-df outdoors

  Let us know how it rates.

  I think that this has been fixed in our latest version 8.5 - documents.software.dell.com/DOC252107

  Please download and upgrade your farm and let us know if you still see this problem.

  If you do, it may be best to save a service request so that we can see exactly what is happening.
