• ASA Checkpoint VPN S2S disorders <>

  Hi all

  I struggled to understand some of my ASA debug output that has a VPN configured with a remote control point.

  In short; the problem lies in the timers to generate a new key P1 & P2. I've defined two timers like 28800 (8 hours). We paired these timers since firewalls Checkpoint automatically deletes SA after a P1 P2 generate a new key. An ASA will remain however send the existing packages with the help of the P2 SA until it remains for life exhausted.

  That said; the IPSec tunnel will go down every 6 hours. It's strange, because the timers were set to 8 hours. After grabbing debug output of the ASA, I found these two messages in the exit of a tunnel to future success:

  2015-12-22,"13:26:17","Local5","debug","ASA-hostname","%ASA-7-715080: Group = REMOTE_PEER, IP = REMOTE_PEER, timer to generate a new key to start P1: 21600 seconds. »

  2015-12-22,"13:26:17","Local5","debug","ASA-hostname","%ASA-7-715080: Group = REMOTE_PEER, IP = REMOTE_PEER, timer to generate a new key to start P2: 24480 seconds. »

  This indicates that new key generation will take place primarily on the actual defined timers run out. How is that possible?

  Running retail "see the crypto ikev1 his ' and ' display peer's crypto ipsec *. *. *. *' validate that the counters are 28800 seconds. After clearing the tunnels, the remaining life expectancy also matches on P1 and P2 and will display a value greater than those listed in the debug output.

  I wonder why these timer values are different in the newspapers of debugging in front the actual configured values and the values generated by the show commands.

  I hope someone can help us with that!

  Hi Hessel

  This behavior is perfectly normal, the lifetime is the maximum that can be used for the regeneration of the keys. The value that you enter in the configuration as life is different from the time to generate a new key of the AA.

  Time to generate a new key must always be less than the life expectancy to allow several attempts in case of failure of the first attempt to generate a new key.  The length varies depending on the platform used, what version of the software, etc.

  If ASA is the initiator, it is normal that it will be given to the key to 75% of the whole of life, this is the time you see to generate a new key it if your timer is 28800 then you should see her generate a new key to 21600 aprox

• VPN SITE-TO-SITE BETWEEN ASA 5505 ASN 5510 DISORDERS

  Hello

  You should make sure that

  • Remote ends of NAT configurations are correct
    • NAT0 or another type of translation is not configured
    • A NAT rule is the substitution of the rule that you have configured for the VPN L2L?
  • Make sure that you have allowed the circulation/connection you are trying
    • VPN traffic is allowed to bypass the 'external' ACL interface on the remote end or the traffic should be allowed in the 'outer' interface ACL?
  • Make sure that the remote host responds to the same type of its local network connection attempt before trying the same thing from a remote location through VPN L2L
    • If a tested service does not work, try another. For example ICMP is not always the best thing to test connections.

  Can you also give us additional context information.

  • This VPN L2L worked, or did it stop working at some point?
  • I assume that you have administrator access to two ASA? Can you perhaps share some configurations
  • What kind of connections you attempt by the L2L VPN?
    • TCP/UDP/ICMP?
    • IP source and destination?
  • You monitor the newspapers of the SAA through the ASDM on the other end? The device at the remote end which does not send anything back on the L2L VPN connection.

  And as a last post a very common configuration that is absent of configurations of ASA during the test with ICMP

  Make sure you two ASAs have below "icmp inspect" configured

  Policy-map global_policy

  class inspection_default

  inspect the icmp

• VPN works with Sierra?

  I understand that the VPN does not yet, with the Sierra

  Is this a Bug? or, if this possibility has been deleted?

  Can we expect support once again with one of the 10.12. # updates?

  This is a very important feature to my office with it, we will not update for Sierra.

  Thank you

  VPNS work very well in Sierra as long as they don't use PPTP. Support for PPTP has been removed because it is not safe. By using a PPTP based VPN is useless. Your data is not safe.

• Tips to add a VPN router to my current network configuration

  Dear all

  My apologies if the answer to this question already exists, however, I searched in many situations and none seem to match what I'm after.

  I currently have an ISP modem/router in Bridge mode connected to a TC of Apple which is my wireless router, I have 2 Express airport connected to this acting as the extensors of the range.  I have a VPN service through the MyPrivate network I activate on the desired device when required and everything works fine.

  What I want to do now is to be able to use my AppleTV and burning Amazon via the VPN as well so you need to add a VPN router in the configuration.  I want to finish with 2 wireless networks running together for these devices who need VPN and those who are not.  I don't want to lose the opportunity to extend the network to express it however airport.

  If someone could explain to me if this is possible and if so how do I set up the network.

  Thanks in advance

  Mark

  Basically you would need a device that supports VPN-passthrough and VLANS for your goals of networking. MyPrivate network, seems to be a VPN SSL, which is a user-server configuration. In other words, you install a client VPN on your Mac and you connect to the VPN network MyPrivate server to establish a VPN tunnel.

  Networking two or more "separated", should be using a router that supports VLAN services. Each segment of VIRTUAL local area network, in essence, would be a separate, she either wired or wireless network or a combination of both. This would probably be the 'easiest' part for the installation program.

  Now how combining the two would be the question, and I don't know what would be the best way, or even if it is possible.

  A few thoughts:

  • Use a router that supports VLANS. Create at least two VIRTUAL LAN segments. One for Apple TV & Burns, one for Internet access in general. Connect the device to VPN client host on the first segment, and configure for Internet sharing.
  • Download a dedicated VPN network application that supports hosting of third-party VPN clients, like yours. You would still need a router that supports VLAN to provided separate network segments.
  • Hire a consultant network. Let them know what you the goals of networking and ask them to offer potential solutions.

• Settings lost VPN - iOS 10.0.2

  I had stored in my iPad VPN settings. VPN connections worked well until the latest iOS update. Now ALL my VPN connections disappeared. To make it even worse-, I am unable to put once again, because there are new mandatory fields: VPN type and shared key. I don't have the slightest idea how to fill them because I never need them when connecting to the VPN through my iMac - please see the screenshot.

  It drives me crazy. I welcome any suggestion.

  Prepare for removal of PPTP VPN before upgrade you to iOS 10 and macOS Sierra

  Preparation for iOS system administrators 10 and macOS Sierra should stop using PPTP VPN connections. Learn about alternatives, you can use to protect your data.

  Even if the PPTP protocol is always available on iOS 9 or an earlier version or OS X El Capitan and earlier, we do not recommend that you use it for secure, private communication.

  Alternatives for PPTP VPN connections

  Try one of these other VPN protocols for authentication by user that are safer:

  • L2TP/IPSec
  • IKEv2/IPSec
  • Cisco IPSec
  • VPN SSL clients on the App Store, such as those of AirWatch, Aruba, Check Point, Cisco, F5 Networks, MobileIron, NetMotion, Open VPN, Palo Alto Networks, Pulse Secure and SonicWall

  More information

  my iphone is running iOS 10

  My computers are running macOS Sierra

  I use Mac OS as host VPN server

  I use the client VPN L2TP iOS 10.

  Firewalls in the system is disabled.

  Typical VPN connections, you use the DNS server of your iPhone and not the DNS server of the network corresponding to your server.  In addition, Hello services are only available on the LAN.  So you have no way to resolve names to IP adrdesses for the network, you are VPNing.

  The only easy solution from an iPhone is to make a list of IP addresses and use them to connect instead of host names.  using IPs will work as long as your ISP does not also use the same internal (like 192.168 or 10.0) IP address than the network that you connect to.

• integrated macOS Sierra Cisco IPsec VPN does not work anymore (impossible to validate the server certificate)

  Hello

  I'm on Sierra, iOS macOS 10 and Mac OS Server 5.2 (on a Mac mini).  (All dated September 21, 2016)

  Because PPTP is no longer supported, I am trying to create L2TP.  Unfortunately, when I try to connect to the server, I get the error "the VPN server has failed. Please check the server address and try to reconnect. »

• How to configure the IKEv2 VPN on Mac OS Server 10.12

  IKEv2 is mentioned in the release notes for Server 5.2 but I can't find instructions anywhere are related.  Anyone know where I could find a tutorial to set up?

  If you are referring to.

  • New IKEv2 authentication method option or specify IPSec disconnect on timeout for VPN

  Then it is a new feature for the profile on Server.app Manager is not a new feature of the VPN on Server.app server. You will need to use a different non-Apple supplied VPN server in order to implement IKEv2.

  Note: as customers El Capitan or later, and iOS 9 or later support IKEv2. (iOS 8 had limited support.)

  Add a vpn connection in ios 10, method chosen in IKEv2, but I don't have the remote ID. My VPN is created in Sonicwall, waiting for quick reply

  Hi cmscan,

  Thank you for using communities of Apple Support.

  I see that you add a VPN connection using IKEv2, but you do not have the remote ID. I know it's important to be able to set up a virtual private network, you can connect using your iPhone. I'm happy to help you with this.

  You must contact your system administrator to ensure that the settings that you must configure the VPN connection. Please see the iPhone user Guide for more information.

  Have a great day!
