On VPN

Hello experts,

Just a simple question to clear my doubts.

I have Microsoft integrated Plains I want to implement our ERP system, I have two branches that I want to stay connected to my HQ in which my SQL Server is hosted, the problem is, these two branch uses same ISP to 4G, and my HQ subscribes to an another ISP that uses a DSL connection.

Q: what are needed to connect all my corporate network through VPN site-to-site.

Hello

Can't really comment regardning 4G

L2L VPN between the branches, the basic requirement would be to have a public IP address that you can configure on a device making the VPN L2L in each branch.

If the public IP address of the VPN device is dynamic, it will take a little more planning and configuration depending on if you use routers or firewalls.

You plan on using firewall Cisco ASA/PIX maybe on the branches or have they already some devices you plan to use?

Using a firewall Cisco ASA plant and perhaps the remote side ASA5505 would give you a chance quite easily connect all 3 sites (thanks to the ASA central) without needing public static IPS to smaller branches.

  • 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?

    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

    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.

    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.

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

    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.

  • VPN using hotspot with ios 10 does not

    I often work off site and use my iPhone AT & T s 6 to attach my work Windows 10 Pro (processor ASUS T300CHI) Tablet.  Although many places I work have Wifi, most only allow VPN I need to connect to my work server.  After updating ios 10 (I'm on 10.0.1), I did have problems engaging, but VPN doesn't work anymore.

    VPN integrated Windows 10 Pro on my Tablet has an automatic configuration that appears to detect the type of configuration (IKEv2/IPSec/PPTP/L2TP, etc.) and you just put in user name and password.  According to my dept IT, the VPN connection in the office not only supports PPTP (I understand has been disabled with ios 10) but also supports IKEv2 and L2TP/IPSec.  Nevertheless, I always left configuration VPN on Windows 10 in auto.  I tried selecting the connection type, but it did not work either.  Generally I get the error "failure of VPN tunnels.

    Any thoughts would be appreciated

    MattyBH,

    Please keep us informed if you were able to solve this problem.  I also have the same problem since the update iOS10.  I think it has to do with Apple, removing the IOS10 PPTP protocol... I was able to confirm the conclusion of downgrading to previous IOS 9.3 and my VPN works very well, unfortunately my users with iPHONE7 cannot sink their IOS and now can not access VPN through hotspots iOS10

  • Not ios10 blocking VPN PPTP connections through personal hotspot?

    I use an iPhone 6 + and was upgraded to ios10, two days ago.

    While I don't have a configuration of the VPN connection on the phone, I connect my computer laptop personal hotspot of the iPhone to use internet and sometimes connect to a VPN.

    Before my upgrade to ios10, my laptop could still connect to the VPN while connected to the hotspot from my iPhone.

    After that I updated to ios10, my laptop does not connect to the VPN I connect to.

    I see reports that Apple has abandoned the use of the connection for PPTP VPN connections on ios10.

    But most of the people having problems seem to be people who connect to their phones directly to the VPN in the iPhone settings.

    In my case, my phone is just acting under the guidance of the internet on my laptop but it seems that it does not obstruct my laptop to connect to a pptp even connection if that should have no impact on the phone itself.

    I went down to ios9 and my laptop can connect again to the VPN.

    But now my Apple Watch does not work with my phone because I improved the watch to os3.

    Any ideas if there is a work around for the connection for pptp connections using the hotspon on ios10?
