L2tp Vpn Client For Mac Os

Mac l2tp vpn setup

First off, what protocol of VPN are you using? OS X Server offers both L2TP (over IPSEC) and PPTP protocols, both of which use different ports. For L2TP you need ports 500 (UDP), 1701 (UDP), and 4500 (UDP). Forward these ports to the same ports internally. For PPTP, it would be ports 500, 1723 (TCP), and 4500, also forward the same internally.

macOS includes a native VPN client. You can use the macOS VPN client to make an L2TP VPN connection to a Firebox.

  1. Check Point sells a version of their VPN-1 Client for Mac OS 8.x/9.x, using vanilla IPsec. Apple's Mac OS X 10.3 (Panther) now includes an embedded VPN client that supports L2TP over IPsec. You're stuck in between with Mac OS 10.2.8 (Jaguar). Jaguar incorporated embedded VPN code but not a graphical user interface to IPsec.
  2. This article will describe how you can configure L2TP/IPsec VPN on MAC OS X. Mac OS X; Access to your Mac OS X with admin or a user that has administrator permissions; Step 1 – Log in to Mac OS X. Click on the icon in the left top corner and click System Preferences.
  3. The MacOSX product feature list discusses interoperability between the MacOSX VPN client and Windows for PPTP and L2TP, so I've been trying to get this to work. I have a Windows Server 2003 RRAS that is configured, working, and with which WinXP desktops can successfully establish an L2TP session using certificates.

Configure the L2TP Network Settings

To prepare a macOS device to make an L2TP VPN connection, you must configure the L2TP connection in the network settings.

  1. In the Apple menu, select System Preferences.
  2. Click the Network icon.
  3. Click the '+' icon in the lower left corner to create a new network interface.
  4. In the Interface drop-down list, select VPN.
  5. From the VPN Type drop-down list, select L2TP over IPSec.
  6. In the Service Name text box, type a name for this VPN connection, such as 'L2TP Firebox'.
  7. Click Create.
    The settings for the VPN connection appear.

You can use the default configuration or you can create your own configuration. These steps use the default configuration.

  1. In the Server Address text box, type the external IP address of the Firebox to connect to.
  2. In the Account Name text box, type your user name as it appears in the authentication server that you use for Mobile VPN with L2TP user authentication.
  3. Click Authentication Settings.
  4. In the Password text box, type the password of the user.
  5. If Mobile VPN with L2TP on the Firebox is configured to use a pre-shared key as the IPSec credential method:
    • Select Shared Secret.
    • In the Shared Secret text box, type the pre-shared key for this tunnel. The pre-shared key must match the pre-shared key configured on the Firebox Mobile VPN with L2TP IPSec settings.
  6. If Mobile VPN with L2TP on the Firebox is configured to use a certificate as the IPSec credential method:
    • Select Certificate.
    • Click Select to select the certificate to use.
    • Make sure you have imported the certificate to the client device. For more information, see Import a Certificate on a Client Device.
  7. Click Apply to save the configuration changes.

Start the L2TP Connection

The name of the VPN connection is the service name you used when you configured the L2TP connection on the client computer. The user name and password are for one of the users you added to the L2TP-Users group. For more information, see About Mobile VPN with L2TP User Authentication.

To start the L2TP connection:

Mac l2tp vpn setup
  1. In the Apple menu, select System Preferences.
  2. Click the Network icon.
  3. Select the VPN connection you created in the Network dialog box.
  4. Click Connect.

After the VPN connection is started, the Connect button changes to Disconnect.

If you want to connect to the non-default authentication server, specify the authentication server in the Account Name text box. For more information, see Connect from an L2TP VPN Client.

The MacOSX product feature list discusses interoperability between the MacOSX VPN client and Windows for PPTP and L2TP, so I've been trying to get this to work. I have a Windows Server 2003 RRAS that is configured, working, and with which WinXP desktops can successfully establish an L2TP session using certificates. I've successfully generated a machine certificate for the MacOSX client using Keychain Access's Certificate Assistant (I generated a signing request, signed in on my Windows CA) and imported it onto the System keychain along with the private key. I also imported my CA cert onto the X509Anchors keychain. The RRAS server certificate has the server hostname (FQDN) as the SubjectAltName extension, and I've used this to specify the VPN endpoint hostname in the MacOSX client L2TP definition. AFAICT, these are the right steps. When I try to initiate the VPN, a network sniff shows that communication indeed occurs between the client and the RRAS server, but the VPN never comes up. I figured how to enable verbose VPN logging on the MacOSX client, and from this I've found that the client & server actually do exchange certificate information. However, racoon appears to get two errors ('ID type mismatched' and 'ID value mismatched') during phase 1 of IKE negotiation immediately after the server's certificate is parsed. The only conclusion I've been able to reach so far is that the Windows 2003 RRAS certificate is somehow unpalatable to the MacOSX racoon, but I haven't been able to figure how to get this working. It's as if racoon somehow can't obtain the SubjectAltName from the server certificate. Since L2TP Windows/MacOSX interoperability is mentioned right out loud in the product feature list, then I'm boldly assuming that -someone- has done this at least once in the past. Oddly, though, I've found nothing in the discussion forums or in Google reporting actual success at this (L2TP, certificates, Windows 2003 RRAS with the MacOSX VPN client). Of course, I could resort to something like VPN Tracker, but I am not quite ready to give up on the MacOSX native VPN client yet. Has anyone else accomplished this? Can you refer me to any documents or other resources on what was done? I already opened a support call on my AppleCare certificate and was told that no help is available for what I'm doing - I was referred to this discussion forum.
