Driver improvement test answers. As more and more users are using remote access VPNs and probably using FortiClient, I wanted to share the errors you are encountering based on the percentage when it fails and some troubleshooting steps around Remote Access VPNs.

4.) Obtain Fortinet SSL Client appx file. In cmd.exe and run “winappdeploycmd install -file FortiSslVpnPluginApp1.0.1024.0ARM.appx -ip 127.0.0.1”. Here FortiSslVpnPluginApp1.0.1024.0ARM.appx is the appx file you obtained, 127.0.0.1 is the IP that shows up when you run “winappdeploycmd devices”. Use Fortinet SSL VPN Client 1.).

  1. The FortiGate IPsec/SSL VPN solutions include high-performance crypto VPNs to protect users from threats that can lead to a data breach. Fortinet VPN technology provides secure communications across the internet regardless of the network or endpoint used.
  2. FortiClient is a Fabric Agent that that delivers protection, compliance, and secure access in a single, modular lightweight client. A Fabric Agent is a bit of endpoint software that runs on an endpoint, such as a laptop or mobile device, that communicates with the Fortinet Security Fabric to provide information, visibility, and control to that device.

Percentage and Possible Issue

Here are some troubleshooting commands for the SSL VPNs on the FortiGate. You can run them from the GUI Console screen or by using your favorite terminal application (e.g. SecureCRT, PuTTY, ZOC, etc.)

Set the terminal to capture the output to a file. This will be useful to provide to TAC if needed.

The commands above will troubleshoot authentication on the FortiGate

Gathering FortiClient Logs

You will want to:

  1. Clear the logs if you have any there.
  2. Set the Log Level to Debug to ensure the highest verbosity. (Make sure to disabled after troubleshooting)
  3. Run the attempt, and then Export logs

These can be uploaded to TAC.

Client

Viewing Performance Settings on FortiGate GUI

You can log into the FortiGate and under the Dashboard, set the time rage filter to 24 Hours for Memory, CPU and even Sessions

On the command line, you can use the following methods and commands

Viewing Performance Settings on FortiGate CLI

diagnose sys top

Once the TOP screen is displayed, you can use the letters below to filter the output differently.

Finally, you may need to trace connections and/or do some packet captures here are two examples of that.

Pinging and Source Pinging

Sometimes you want to perform a straight ping to test connectivity from the firewall to a remote access VPN device. You can do that with the standard exec ping %host% however sometimes, you may want to source the ping from the inside interface or dmz interface. Below are the commands.

Flow Trace

Now I will show a flow trace from my computer to 4.2.2.2

In the output, it will show you what interface the connection came in on, because of the function-name enable you will see NAT, Routing, etc, IPS, offloading to NPU and SPUs, etc.

Sessions

You can also see the sessions using the following commands

Use the filter that work for you from a source or destination as well as ports

With this filter, you can clear the sessions based on the filter you created by issuing the diagnose sys session clear NOTE: Without the filter in place, you will clear ALL sessions on the FortiGate. It is always a good habit to run diag sys session filter ? to list the filter you have configured.

Packet Capture

You can either use the GUI or the CLI to run packet captures.

The verbosity is controlled by the following:

You can use the GUI by going to Network then Packet Capture then Create . You will then be able to choose the interface you want to capture on and optionally you can enable the filters, and choose as needed. This will give you the opportunity to download the PCAP file and launch it with Wireshark, which you SHOULD have on your computer

Hope this helps

    Select to configure and enable tunnel mode access. These settings determine how tunnel mode clients are assigned IPv4 addresses.

    Enable Split Tunneling

    Select so that the VPN carries only the traffic for the networks behind the FortiGate unit. The user’s other traffic follows its normal route.

    Routing Address

    If you enable split tunneling, you are required to set the address that your corporate network is using. Traffic intended for the routing address will not be split from the tunnel.

    Source IP Pools

    Select an IPv4 pool for users to acquire an IP address when connecting to the portal. There is always a default pool available if you do not create your own.

    IPv6 Tunnel Mode

    Select to configure and enable tunnel mode access. These settings determine how tunnel mode clients are assigned IPv6 addresses.
