Macos Usg Vpn Request Timeout For Icmp_seq

Download here

macOS Server has long had a VPN service to allow client computers to connect to a network even when they’re out of the home or office. And as with many a service on macOS Server, this is one of the easiest VPN servers you’ll ever setup. The server was once capable of running the two most commonly used VPN protocols: PPTP and L2TP. And while PPTP is still accessible via the command line, L2TP is now configured by default when you setup the server using the Server app.

MacOS: To disable the. Check the ZyWALL’s IKE logs to make sure it is receiving a request to establish the VPN. By default the ZyWALL is.

Setting Up The VPN Service In macOS Server
To setup the VPN service, open the Server app and click on VPN in the Server app sidebar. The VPN Settings screen has a number of options available, as seen here.

Mac OS X 10.11.4 El Capitan; Bridge interface with tap interface as a member; qemu is running a VM instance of IncludeOS; The bridge is created as follows: sudo ifconfig bridge5 create sudo ifconfig bridge5 10.0.0.5 netmask 255.255.255.0 up The tap interface is a tuntap device and is linked to the bridge as follows: sudo ifconfig bridge5 addm tap0.

The VPN Host Name field is used by administrators leveraging profiles. The setting used becomes the address for the VPN service in the Everyone profile. L2TP requires a shared secret or an SSL certificate. In this example, we’ll configure a shared secret by providing a password in the Shared Secret field. Additionally, there are three fields, each with an Edit button that allows for configuration:

  • Client Addresses: The dynamic pool of addresses provided when clients connect to the VPN.
  • DNS Settings: The name servers used once a VPN client has connected to the server. As well as the Search Domains configuration.
  • Routes: Select which interface (VPN or default interface of the client system) that a client connects to each IP address and subnet mask over.
  • Save Configuration Profile: Use this button to export configuration profiles to a file, which can then be distributed to client systems (macOS using the profiles command, iOS using Apple Configurator or both using Profile Manager).
  • Shared Secret: A passphrase that must be supplied by the client prior to getting a username and password prompt.

Once configured, open incoming ports on the router/firewall. While deprecated(ish) PPTP runs over port 1723. L2TP is a bit more complicated, running over 1701, but also the IP-ESP protocol (IP Protocol 50). Both are configured automatically when using Apple AirPorts as gateway devices. Officially, the ports to forward are listed at http://support.apple.com/kb/TS1629.
Using The Command Line
I know, I’ve described ways to manage these services from the command line before. The serveradmin command can be used to manage the service as well as the Server app. The serveradmin command can start the service, using the default settings, with no further configuration being required:
sudo serveradmin start vpn
And to stop the service:
sudo serveradmin stop vpn And to list the available options:
sudo serveradmin settings vpn
The output of which shows all of the VPN settings available via serveradmin (which is many more than what you see in the Server app:

To disable L2TP, set vpn:Servers:com.apple.ppp.l2tp:enabled to no:
sudo serveradmin settings vpn:Servers:com.apple.ppp.l2tp:enabled = no
To configure how long a client can be idle prior to being disconnected:
sudo serveradmin settings vpn:Servers:com.apple.ppp.l2tp:PPP:DisconnectOnIdle = 10
By default, each protocol has a maximum of 128 sessions, configureable using vpn:Servers:com.apple.ppp.pptp:Server:MaximumSessions:
sudo serveradmin settings vpn:Servers:com.apple.ppp.pptp:Server:MaximumSessions = 200
To see the state of the service, the pid, the time the service was configured, the path to the log files, the number of clients and other information, use the fullstatus option:
sudo serveradmin fullstatus vpn

Which returns output similar to the following:
vpn:servicePortsAreRestricted = 'NO' vpn:readWriteSettingsVersion = 1 vpn:servers:com.apple.ppp.pptp:AuthenticationProtocol = 'MSCHAP2' vpn:servers:com.apple.ppp.pptp:CurrentConnections = 0 vpn:servers:com.apple.ppp.pptp:enabled = yes vpn:servers:com.apple.ppp.pptp:MPPEKeySize = 'MPPEKeySize128' vpn:servers:com.apple.ppp.pptp:Type = 'PPP' vpn:servers:com.apple.ppp.pptp:SubType = 'PPTP' vpn:servers:com.apple.ppp.pptp:AuthenticatorPlugins = 'DSAuth' vpn:servers:com.apple.ppp.l2tp:AuthenticationProtocol = 'MSCHAP2' vpn:servers:com.apple.ppp.l2tp:Type = 'PPP' vpn:servers:com.apple.ppp.l2tp:enabled = yes vpn:servers:com.apple.ppp.l2tp:CurrentConnections = 0 vpn:servers:com.apple.ppp.l2tp:SubType = 'L2TP' vpn:servers:com.apple.ppp.l2tp:AuthenticatorPlugins = 'DSAuth' vpn:servicePortsRestrictionInfo = _empty_array vpn:health = _empty_dictionary vpn:logPaths:vpnLog = '/var/log/ppp/vpnd.log' vpn:configured = yes vpn:state = 'STOPPED' vpn:setStateVersion = 1
Security folk will be stoked to see that the shared secret is shown in the clear using:
vpn:Servers:com.apple.ppp.l2tp:L2TP:IPSecSharedSecretValue
Configuring Users For VPN Access
Each account that accesses the VPN server needs a valid account to do so. To configure existing users to use the service, click on Users in the Server app sidebar.
At the list of users, click on a user and then click on the cog wheel icon, selecting Edit Access to Services.
At the Service Access screen will be a list of services that could be hosted on the server; verify the checkbox for VPN is highlighted for the user. If not, click Manage Service Access, click Manage and then check the VPN box.
Setting Up Client Computers
As you can see, configuring the VPN service in macOS Server 5.4 (running on High Sierra) is a simple and straight-forward process – much easier than eating your cereal with a fork and doing your homework in the dark. Configuring clients is as simple as importing the profile generated by the service. However, you can also configure clients manually. To do so on a Mac, open the Network System Preference pane.
From here, click on the plus sign (“+”) to add a new network service.
At the prompt, select VPN in the Interface field and then either PPTP or L2TP over IPSec in the VPN Type. Then provide a name for the connection in the Service Name field and click on Create.
At the list of network interfaces in the Network System Preference pane, provide the hostname or address of the server in the Server Address field and the username that will be connecting to the VPN service in the Account Name field. If using L2TP, click on Authentication Settings.
At the prompt, provide the password entered into the Shared Secret field earlier in this article in the Machine Authentication Shared Secret field and the user’s password in the User Authentication Password field. When you’re done, click OK and then provided you’re outside the network and routeable to the server, click on Connect to test the connection.
Conclusion
Setting Up the VPN service in macOS Server 5.4 is as simple as clicking the ON button. But much more information about using a VPN can be required. The natd binary is still built into OS X at /usr/sbin/natd and can be managed in a number of ways. And if you’re using an Apple AirPort as a router (hopefully in a very small environment) then the whole process of setting this thing up should be super-simple.

Hi guys,

So here’s my issue. I connect to my work’s office through VPN in order to access our development servers etc. through our local network because some things are blocked from the outside. I’m having issues connecting to local IPs through the VPN. My local IP at home is 192.168.1.53 and my IP on the VPN is 192.168.1.200. Both networks use a subnet mask of 255.255.255.0.

For example I’m trying to connect to a file server at 192.168.1.191 (on the remote network). But when I ping the IP in terminal I get

Scott$ ping 192.168.1.191

For some reason my mac can’t find the local IP of 192.168.1.191. I’ve tried to put my VPN interface as the primary interface in the System Preferences and checked the ‘send all traffic through VPN’ but nothing helps. And I know for a fact that the VPN works because when I ping 192.168.1.1 I get 200–300 ms of latency (no way that this is my home router, has to be the one in my work’s office 6000 miles away).
