  What is the best VPN for my MacBook Pro running Yosemite

  The question is really not much sense.

  A VPN is not something that you install on a computer. It's a service that you connect to, as such, there is no better for a specific type of computer.

  What exactly you need to accomplish with a VPN?

  Usually, a VPN is used to connect to a remote network and use its resources, such as printers and servers, as if you were connected locally to them.

• Easy VPN debugging?

  Hi we have problems with a client that connects to our Cisco via EasyVPN 2800. I would like to know the exactly effective way to debug and resolve problems and the tunnel to the EasyVPN. Thank you.

  No, you cannot filter debugging.

  However, if you have problems with 1 single connection, only this one should be in debugging.

  The work of VPN will give little or no debugging messages (only to generate a new key or termination).

  Please rate if this helped.

• 3925, IPsec LAN - LAN VPN tunnel command unavailable

  Hello

  I am looking to use one of my 3925 to create a VPN IPsec LAN - LAN tunnel with another site.

  I was under the impression that I needed to get a license of securityk9 installed and then I was good to go.   I got a temporary license for 60 days and it is installed, but none of the commands I need to create the tunnel are appearing for me.

  I am using the command "crypto isakmp", but which does not appear:

  Router (config) #crypto?
  CA Certification Authority
  main activities key long-term
  public key PKI components

  Here's my license to show:

  Function index 2: securityk9
  Time left: 633 weeks 4 days
  Period of opportunity: 0 minute 0 second
  License type: assessment
  The license status: active, don't use, EULA accepted
  Number of licenses: not counted
  License priority: bass

  Don't know why there are so many weeks left

  Thoughts on that?

  Thanks in advance.

  just a little thing

  have you tried in config guest... . License to start and so on.

  as you said the router to use the license that you have installed.

  If you are a license sh what do you get?

  Good luck

• Best VPN server

  I use the VPN server through Server 5.1. However, I recently bought an EdgeRouter POE, and I plan to change to its VPN. Can someone offer advantages/disadvantages for one against the other?

  Thank you

  Jeff

  I have no experience using the EdgeRouter and it took quite some dig able to determine that this was the case to all VPN. It seems mainly focused on being a router Ethernet to Ethernet. However as mentioned, I finally found a reference, which suggests he can do the following VPN protocols.

  • IPSec Site to Site and remote access
  • OpenVPN Site‐to‐Site and remote access
  • RAS PPTP
  • Remote access L2TP
  • PPTP client

  Download and read the whole manual I don't remember not its VPN features.

  I can say that I gave up on VPN server own Apple as it supports only L2TP and PPTP that these two days are considered to be weak from a security point of view and which can be used for VPN on demand configurations. I now use StrongSwan5 which allows to make a Linux server

  • IKEv2 Site to Site and remote access
  • IPSec Site to Site and remote access

  Both being able to VPN on demand.

  IKEv2 is currently considered the most secure VPN solution. IKEv2 is supported the use of VPN client built into El Capitan and iOS 9.

  StrongSwan5 works with the built-in VPN Apple customer and StrongSwan5 supports the use of SSL certificates, it also supports force all traffic through the VPN - a common requirement of companies configuration VPN connection.

• Best VPN for Mac Office-based network protocol Option

  I do research of the solutions for the installation of a VPN to a position of up to 15 stations for a customer.  All stations are pimps and El Capitan OS X running.

  I will implement a router Cisco VPN rv130.  I am to decide what the Protocol would be preferable to restrict in Cisco IPSec or OpenVPN using a third-party VPN client.

  I look forward to any advice or ideas for better, safer solution.

  Thank you!

  We usually install OpenVPN Access Server running in VirtualBox or ESXi at our customers and connect to the OD/AD. Put in VirtualBox on Mac is a very simple solution that just works. The integrated web portal is also very clever. $ 9 / user/year and a charge moderate for failing to manage everything you do when even (create and delete users in OD/AD)

  Now; since El Capitan, it is not possible to install the client incorporated without disable SIP. Use TunnelBlick client if you do not want to disable SIP during the installation of OpenVPN.

• best practices of command buttons

  Hello

  I would ask how others view their GUI with several command buttons (OK Boolean button).

  For example, it is a simple application where the user can start data acquisition by clicking on a button with text 'Start monitoring '. Instead of having another button with text "Stop monitoring", usually I just change the label text to "Stop monitoring" button, so it is obvious to the user that clicking on that will stop the process of monitoring the implementation (in the case of this button, I read the text of the actual label with property node in order to decide what message action to the loop the loop handler data acquisition of) GUI).

  If I have another button with the label as "Record of startup file" text, I do the same way: after saving the file, change the text 'Stop-save file.

  To avoid unnecessary additional programming, this button is in the enabled state if the application is already in the State of "monitoring". In addition, if there is a current folder (+ DAQ obviously), the user cannot press the button "stop monitoring". So according to the status of applications, some of the buttons are enabled, some in 'grey disabled' State.

  I wonder how others do their app/GUI?

  I don't know if it's a good way to do, but at least I can avoid check additional status of programming and by minimizing the number of buttons...

  I use the Boolean options text in the Properties menu where you can have different text for the States TRUE and FALSE to your buttons.  This eliminates some of the code that it sounds as you write.

  Play / Pause are the two options I usually use if buttons.

• DHCP server for debugging VPN clients

  We are DHCP configuration to a DHCP server for SSLVPN customers on our ASA 8.2 running, and it does not work yet.

  I set the DHCP server to the tunnel profile to use, set the scope of the network dhcp for the group - that seems to be all that is needed.

  Currently, the problem is I'm having trouble finding debug commands that provide detailed information on what is happening with DHCP queries.

  Debug only the DHCP-based controls seem to be:

  DHCPC Client DHCP information

  DHCPD dhcpd information, and
  dhcprelay DHCP Relay information

  I ' ve tried the client and relay debugs and I see is that the client is not giving an IP address valid. " 0.0.0.0/0.0.0.0

  The DHCP server is not a request from this ASA for the network defined in the dhcp-network for the group scope, and we see nothing on the DHCP server in debugging results.

  Any suggestions would be welcome.

• Aligning Yagi wireless airiels (best practices)

  Hi all

  In the last months, I installed several WLAN using Cisco's YAGI antennas. They seem to be a nice piece of kit to work with. Although, because they are pretty directional. Most of my installation time is spent lining up properly...

  I can't help thinking there must be something better than two guys on the end of the stairs with 2 - way radios! a bit left!, just a little bit!, down! :)

  How do the rest of do you? Y at - it special tools for the job? Maybe a laser alignment tool any...

  I know that you can measure the intensity of the signal in the ios using debug commands. But it is a little too late at the time where your bottom!.

  I look forward to your responses.

  Sincere friendships & thank you

  This is a GPS and a good compass can be your best friends.

  Go to site A, take a snapshot from the same place (save location). Go to site B, then tell the GPS you want 'goto' site has... it will give you a bearing (some will give you a pointer arrow).

  Set the antenna of station B this bearing. Most practitioners can also give you a reading decent altitude to help with 'altitude adjustments.

  Take a read / snapshot of the location of site B.

  Return to Site A and set this antenna for the running of the Site B (and possibly the elevation).

  Directions to RSSI allows to tune 'em if necessary / if necessary.

  I know some people who put a scope on the boom of the yagi and aim a strobe attached to the other antenna.

  Anything that works...

  Hello

  You can use terminal no monitor to turn off the same and also check this link for setting up an external syslog server to collect system logs.

  you use syslog software installed in the external system to collect the newspapers.

  the best bet would be kiwisyslog s/w, which is very easy and roubst.

  You must configure your router and point the same to send messages to the external system.

• with 2 levels of firewall VPN remote access

  We have two firewalls of different suppliers, with the first level being a cisco firewall. The Setup is:

  ISP <-->(router) <-->(Cisco Firewall) <-->(another firewall of the seller) <-->LAN internal

  We need to give remote users (with installed VPN clients), internal access to certain resources in the local network.

  My question, where can I configure my IPSec VPN, for best security practice, given that my router, Firewall-1 & Firewall-2, all take care the VPN features.

  I also want to allow remote users (who are they assigned local IP internal IP pool), to allow to specific resources (servers read) & specific ports.

  So can implement an access list, after that the VPN is terminated & users get their local pool IPs?

  Thank you & best regards

  Hello, MD,.

  What is the version of the code that you run on your PIX? If you run version 6.x of the code, then you will not be able to use the vpn-filter command to restrict access to certain IP addresses.

  You should run version 7.x for it where you can specify an ACL to restrict traffic.

  In addition, only some PIX firewalls can be upgraded to version 7.x, please look in the link given below

  http://www.Cisco.com/en/us/products/HW/vpndevc/ps2030/products_qanda_item09186a00805b87d8.shtml#Q1

  If you can not pass the PIX to version 7.x, then you will need to use another VPN device.

  Hope that answers your questions. Rate this post if it helped.

  See you soon,.

• Ask about hub and spoke VPN between several sites

  Hello

  I currently have a 'hub' ASA 5505 that connects to 4 sites running 877 routers.

  Since the network hub, I can connect to all the sites fine but what I would do is almost to compartmentalize the different VPN links in small groups.

  The ASA 5505 hub mainly provides IP telephony via the VPN from a PBX allowing users at the other end of the VPN to make outgoing calls and receive incoming calls. However, a couple of the sites would be able to call them internally through the hub. It must obviously be allowed between their different networks of traffic.

  Currently, when you try an internal call rings, but there is no audio data anyway. I guess that's due to restrictions of access list. I don't know yet if what I'm trying to achieve is possible as I'm a bit of a rookie, but any help would be appreciated. I have attached the hub and 2 rays below.

  The ideal final result would be the interconnectivity between the two rays through the hub, it seems reading as its possible, but I do not understand my head around it! It would involve using different subnet to the hub masks?

  Any help would be greatly appreciated!

  Thank you

  Jack
