• PIX 515 does not recognize the DIMM 128 MB

  PIX 515 does not recognize the DIMM 128 MB. Won't recognize only 32 MB. Also when the upgrade to 7.0, I get an error message that it has not enough flash, but I have 16 MB of flash needed.

  PIX 515 not recognizing 128 MB may be due to, in my opinion, pix-515 supports 64 MB. PIX-515e can support 128 MB. Now error Pix by reading not enough flash I got the same message when I tried to load 7.0 release using the tftp with padding interface configured to the local network with an attached TFTP server segment. I then tried the interruption during the startup control method, once the PIX reached ROMMON > issue 'auto of e1 interface', 'address 10.0.0.1', server 10.0.0.2, there are a few other commands. You may be familiar with them, otherwise use find under cisco.

  After the upgrade yesterday from Vista to Windows 7, now my Cisco VPN does not work and I get an error message titled: grounds 440 driver fault.  Any ideas to fix this?

  This was the solution!  The works of vpn as $ 1 million now.  I followed the instructions above to enter the uninstall program and selecting the repair option.  I rebooted the machine, then used the troubleshooting on vpn software compatibility option.  Selected Windows windows xp (service pack 2) as the correct software and cisco vpn client started right up.

  Thanks, Nick!

• PIX and ASA static, dynamic and RA VPN does not

  Hello

  I am facing a very interesting problem between a PIX 515 and an ASA 5510.

  The PIX is in HQ and has several dynamic VPN connections (around 130) and IPsec vpn remote works very well. I had to add a PIX to ASA L2L VPN static and it does not work as it is supposed to be. The ASA 5510, at the remote end, connects and rest for a small period of time, however, all other VPN connections stop working.

  The most interesting thing is that ASA is associated with the dynamic map and not the static map that I created (check by sh crypto ipsec his counterpart x.x.x.x). However, if I make any changes in the ACL 'ACL-Remote' it affects the tunnel between the PIX and ASA.

  Someone saw something like that?

  Here is more detailed information:

  HQ - IOS 8.0 (3) - PIX 515

  ASA 5510 - IOS 7.2 (3) - remote provider

  Several Huawei and Cisco routers dynamically connected via ADSL

  Several users remote access IPsec

  A VPN site-to site static between PIX and ASA - does not.

  Here is the config on the PIX:

  Crypto ipsec transform-set ESP-3DES-ESP-SHA-HMAC-IPSec esp-3des esp-sha-hmac

  Dyn - VPN game 100 Dynamics-card crypto transform-set ESP-3DES-ESP-SHA-HMAC-IPSec

  The problem is that the ASA has a crypto acl defined between host and network, while the remote end has to the network.

  Make sure that the acl is reversed.

• PDM with PIX 515 does not work

  I just upgraded our PIX 515 of 6.1 to 6.2. I also added support FOR and loaded the version 2.1 of the PDM. I am trying to browse the MDP, but I can't. What Miss me?

  Hello

  have you added the following lines to your config file and have you used HTTPS to access the pix (http is not taken in charge, only https)?

  Enable http server

  http A.B.C.D 255.255.255.255 inside

  A.B.C.D is the ip address of the host from which you are trying to reach the pix with the pdm.

  If you're still having problems after the addition of these two lines, you might have a look at this page:

• PPTP VPN does not work on Iphone Personal Hotspot

  Hello

  I've just updated to iOS 10 yesterday and now all my devices I use to connect to the personal hotspot on my iphone are not able to establish PPTP VPN connections. I was aware of the PPTP client are disabled in the iOS, but has actually blocked PPTP are not used by devices that connect to the Personal Hotspot?

  Please help ASAP, I know there are many more end-users like me having the same problem.

  Hello

  Apple does not recommend using the PPTP protocol for secure and private communication.

  iOS 10 and macOS Sierra intentionally delete a VPN profile PPTP connections when a user upgrades from their device.

  Apple recommends using another VPN protocol which is safer:

• I use a VPN in AirPort Express. I've updated firmware for 7.7.7 and DNS assigned by my VPN does not work anymore. Upon entry, the icon 'internet' in utility Airpot turns brown, and the internet stops completely. Anyone have any idea?

  Why my internet connection dies? I use a VPN to my internet at home. I put the DNS numbers supplied by the company VPN in my airPort extreme, which, in turn, provides wireless for home. It worked perfectly until I updated to firmware 7.7.7. Suddenly the green light next to the 'internet' in airport Utility icon went Brown, and it is therefore most all internet. I put numbers in DNS to my ISP, and internet provider is displayed again. All the other numbers in DNS, whether it's Google, OpenDNS or VPN to stop the dead from the internet. Anyone has an idea about this?

  Airport base stations, are at best, a VPN-well past that device. It is a server or a VPN client. Upgrade to the latest firmware does not change this fact.

  To create a VPN tunnel using the AirPort Express Terminal, your computer must be running a VPN client that connects to a VPN server somewhere on the Internet. What DNS servers you use should make no difference with VPN.

  If the ISP-supplied DNS servers do not work, I would say that you contact your ISP to find out why they don't allow you to use them.

  What we need to study is more why you lose Internet connectivity when changing the DNS servers of your ISP. Please check with them and to report back, then we can try to help.

• Check sensor SFR with FireSight via VPN - does not work

  Hello security experts.

  I have an ASA5515-X with SFR installed 5.4.0 and manage with 5.4 FireSight installed on the virtual machine on LAN and I record the sensor without any problem but when I try to register the sensor to FireSight via VPN I can't do. The interface on the ASA management has no intellectual property nor nameif configured and the interface is connected to the switch, SFR has the IP even configured as LAN addressing. I can see traffic being exchanged between the sensor and the FireSight but I can't save the sensor.

  Has anyone managed to register the sensor via VPN? Is there something else to be configured in order to save the sensor with the MC via the VPN?

  The delay between the Firesight and the sensor (on WAN and VPN) I get between 80 and 100 ms, what could be the problem?

  Thank you very much!

  Remi

  Hello

  If you are unable to telnet from DC to the sensor on the port 8305 delivers connectivity then.

  Can try you to ping from sensor to DC:

  ping -M do -c 20 -s 1572 

  By default, the MTU is 1500 on eth0, if the ping does not work I will suggest to lower the MTU on the interface and see if it works. See also: / var/log/messages | grep sftunnel and see the error messages on DC and sensor and send it to me everywhere. Best regards, Aastha Bhardwaj rate if this is useful!

  Wang,

  Thanks for the update! Happy in his work.

  The commands below are for the search for group policy.

  AAA authorization groupauthor LAN

  card crypto isakmp authorization list groupauthor REMOTEACCESS

  Since then, you have configured Group Policy (name, presharedkey, etc.) locally on the router, you must specify the router where to look for the isakmp policy when VPN cace tries to connect.

  I hope it helps.

• Cisco Anyconnect VPN does not work in windows 7 64 bit

  Hello
  I found that the cisco anyconnect (version 3, any series) does not work in windows 7 (64-bit).
  The vpn is connected, but there is not any internet access.

  I tried to solve the problems of:

  -Disabling the firewall.

  -disable the anti-virus etc.

  But while I tried using with 32 bit, it works very well.

  Also, I found that there is not a specific version of anyconnect vpn for only 64-bit.

  Do any body have the idea how to solve this problem, either it's a bug of cisco vpn itself?

  Certainly, you just need to install a later version of AnyConnect.  You need a Cisco, for example a SmartNet maintenance contract, to download the new versions.

• L2l ios VPN does not

  Hi all

  I am reproducing my client on the GNS scénarion.

  It is a frank l2l ios vpn and I use on two NAT routers.

  When I train trigger (ping using the source interface) VPN, VPN is not coming, and there is no error during the isakmp debug

  Please go through the configuration below and suggest me

  Thanks toufik

  It does not appear to be configured for each LAN routing. May need to configure the default route on each router to point to the other.

  In addition, enabling the option 'enable isakmp crypto '.

  All the other configuration looks OK.

• VPN does not connect in some places

  I have a laptop running v5 Cisco VPN Client that connects to the office of some places network fine, but not other places.  and in the places where it does not connect, it connects fine to another unrelated network.  by "does not connect", I mean that I can't access any of the resources on the office network - the client software seems to work, but there is no access, I cannot ping anything on the office network.  What would cause this?  Here is the log file from a location where it does not connect to the office network:

  Could you go through a PAT instrument, so you are not able to access resources after the VPN is connected because ESP packets usually will not go through a PAT tool.

  What must be configured on the VPN server is to allow NAT - t (NAT Traversal), IE: encapsulation of the ESP package in UDP or TCP packet, then it passes through PAT instrument very well.

  What server VPN should you terminate the VPN Client?

  The command to activate on the SAA would be: crypto isakmp nat-traversal 20

  Let me know if you have other devices like the VPN server.

  Hope that helps.

• Win2K NAT would be from 1650 to a PIX 515 - does not

  Hello

  :

  I have a working VPN config on my 515 (6.2.2) and can tunnel from one host with a valid external IP without any problem. But, with a NAT would be customer, nothing seems to work.

  I use RADIUS to authenticate after using a password for the group. Here is the sequence of events.

  (1) client machine as a 10.0.0.1 address, NAT had a public address to come into the port of 'outside '.

  (2) the client connects, the user enters GANYMEDE password and is connected.

  (3) the user tries to browse any service and can not.

  (4) if the user switches DNS to an external server, the portion of the split tunnel internet works fine but inside is still broken.

  (5) clients with static IP addresses that are publicly routable connect and can perform all internal and external activities of split tunnel.

  Excerpts from config. I'm doing something wrong?

  You do not have something wrong. The problem is that NAT (NAT actually PAT, port) and IPSec is not working very well, and many features PAT can PAT IPSec traffic to all (PIX included until version 6.3).

  The problem is that PAT depends on using the port number TCP or UDP source as a way to differentiate between sessions, because they are all PAT would be from the same source IP address. However IPSec (ESP at least), tracks right on top of IP, in other words, it is NOT a TCP or UDP protocol, and therefore has no associated port number. It breaks most of the PAT devices.

  The reason for which you can build your tunnel initially, it is that it is all done by ISAKMP, which is a UDP protocol, which can be PAT would be fine. Once the tunnel is built however, all encrypted data are sent by packs of ESP, which as I said, is not a TCP or UDP protocol.

  Trnalsations NAT static work cause they do not rely on the use of the port number, they just change the address of the source that works very well with ESP.

  There is not much you can do about it. If you were closing the VPN into a VPN3000 concentrator, it has a feature called IPSec through NAT, which encapsulates all ESP packets in a UDP packet, which can then be PAT would be properly. The PIX, unfortunately, doesn't have this feature. The only solution is to get a NAT device that manages properly the IPSEc. Surprisingly, some of the less expensive devices on the market handle it, but you should check with each manufacturer to be sure.

• VPN does not work with the ip address of overlap?

  When I plugged my adsl router and I have ip address is 10.1.1.1/8 can I use remote access vpn closing on firewall and authentication works very well and I put the ip address of the pool is 10.7.0.1/16 but I can not access this local lan if I made up of my pc and got 2x2.102.x.y ip address then I connected I can't access no problem local network and vpn remote access authentication.

  It is question of routing on pc with overlapping ip or not?

  Please clarify or provide useful link

  Thank you

  Hello

  It seems that it is a problem of nat - t.

  Make sure that the head of VPN network has "isakmp nat - t" (if that's a PIX). If a hub, make sure that "IPsec NAt - T" is enabled.

  Additionally, make sure that on the client, "Enable Transparent tunneling" is checked, with IPSec over UDP NAT/PAT selected.
