Starting an SSL-VPN tunnel CPS test
This test establishes a SSL-VPN tunnel connection and completes a full of HTTP transaction through it. It creates one HTTP(FTP) transaction per tunnel.
|
The tunnel is only established if configured in empty tunnel mode. |
To start an SSL VPN CPS tunnel test:
- Go to Cases > Performance Testing> VPN> > SSLVPN > CPS to display the test case summary page.
- Click + Create New to display the Select case options dialog box.
- Configure the Inner Traffic and click OK to continue.
-
Set the server network to Peer Network.
If Fortigate SSLVPN policy has disabled NAT mode, you need set the Internal IP assigned by Fortigate.
If Fortigate SSLVPN policy has enabled NAT mode, you need to set apeer IP.
- Set Specifics for Load and Client. See the table below.
-
Set Inner protocol case Specifics >HTTPCPS.
Simulated Users Number of simusers in a Tunnel.
SSL VPN tunnel CPS Test Case configuration
| Settings | Guidelines |
|---|---|
| Basic Information | |
| Name | Specify the case name, or just use the default. The name appears in the list of test cases. |
| Ping Server Timeout | If a FortiTester connects to a DUT via a switch, the switch might cause a ping timeout, resulting in the test case failing to run. If this occurs, increase the timeout. The default is 15 seconds. The valid range is 0 to 600. Note: You can disable this end-to-end connectivity test by entering a setting of 0. If the DUT is unable to return packets, it is recommended you do so. |
| Number of Samples | Select the number of samples. The default is 20, which means the web UI will show the last 20 sample data (about 20 seconds) in the test case running page. You can select 20, 60, or 120. |
|
Script Config |
Select the script that will run before/after the test. To create a script, see Using script object templates. |
| Steady Duration | Specify the test duration. The default is 10 minutes. The test stops automatically after the duration you specify. |
| Stopping Status in Second | The maximum time out in seconds allotted for FortiTester to close all TCP connections after the test finishes. |
|
DUT Monitor |
Select to monitor a FortiGate device under test (DUT). If selected, you can monitor the DUT from the DUT Monitor tab on the management interface. To create a DUT monitoring, see Using DUT monitoring. |
| Network Settings If you have selected a network config template, the network settings automatically inherit the configurations in the template. See Using network configuration templates for the description of network settings. |
|
| Load | |
|
Mode |
Simuser: Simulated users. Simuser simulates a user processing through an Actions list one at a time. It allows you to determine the maximum number of concurrent users your device, infrastructure, or system can handle. |
| Simulated Users |
Number of users to simulate. |
|
Ramp Up Time |
Time in seconds for traffic to ramp up when you start the test. |
|
Ramp Down Time |
Time in seconds for traffic to ramp down when you stop the test. |
| VPN Gateway Port | Specify the VPN gateway port number. |
| VPN Username | Enter the VPN username. |
| VPN Password | Enter the VPN password. |
|
Tunnel mode |
Select TCP or UDP. |
| Client Profile | |
|
Client Close Mode |
Select the connection close method: 3Way_Fin or Reset. |
|
Quiet Shutdown |
Enable to apply safe shutdown procedure to SSL connections by sending SSL alert to the peer. |
|
Available SSL Versions |
Select SSL versions. TLSv1.3 and other SSL versions are mutually exclusive. This means you can’t select TLSv1.3 at the same time with other SSL versions. |
|
SSL Ciphers |
Select one or more SSL ciphers from the list. |
| Session Resumption |
This option applies only to TLS v1 and TLS v1.2. It does not apply to TLS v1.3. |
|
Enable Client Certificate |
Enable the client authentication for HTTPS cases. |
| Piggyback Get Requests | If enabled, this means an acknowledgement is sent on the data frame, not in an individual frame. |
| Source Port Range | Specify a client port range. The valid range is 10,000 to 65,535, which is also the default. |
| IP Change Algorithm/Port Change Algorithm | Select a change algorithm: Increment or Random. This setting determines how the system changes source/destination IP addresses and ports to simulate multiple client requests. The Increment option uses the next IP address or port in the range, for example: 10.11.12.1 -> 10.11.12.2; port 10000 -> 10001. The Random option selects an IP address or port in the range randomly. |
| Client/Server TCP Options | |
| TCP Receive Window | The receive window in which you want the TCP stack to send TCP segments. The receive window informs the peer how many bytes of data the stack is currently able to receive. The supplied value is used in all segments sent by the stack. The valid range is 0 to 65535. |
| Delayed Acks | Select to cause the TCP stack to implement the Delayed ACK strategy, which attempts to minimize the transmission of zero-payload ACK packets. Acknowledgments will be deferred and should be piggybacked on top of valid data packets. If successfully deferred, these acknowledgments are free, in the sense that they consume no additional bandwidth. |
| Delayed Ack Timeout | If you select Delayed ACKs, use this timeout value to specify the maximum time the TCP stack waits to defer ACK transmission. If this timer expires, the stack transmits a zero-payload acknowledgment. |
| Timestamps Option | Select to add a TCP time stamp to each TCP segment. |
| Enable Push Flag | Select to set the TCP PSH (push) flag in all TCP packets. This flag causes buffered data to be pushed to the receiving application. If deselected, the PSH flag is not set in any TCP packet. |
| SACK Option | Select to enable TCP Selective Acknowledgment Options(SACK). |
| Enable TCP Keepalive | Select to enable TCP Keep-alive Timer. |
| Keepalive Timeout | If you enable TCP Keepalive, use this timeout value to specify the maximum time to send your peer a keep-alive probe packet |
| Keepalive Probes | If you enable TCP Keepalive, use this value to specify the maximum probes to detect the broken connection. |
| Override Internal Timeout Calculation | Select to override the TCP stack calculation of the retransmission timeout value. |
| Retransmission Timeout | If you select Override Internal Timeout Calculation, use this value for the first transmission of a particular data or control packet; it is doubled for each subsequent retransmission. |
| Retries | The number of times a timed-out packet is retransmitted before aborting further retransmission. If the client does not receive a response after the configured number of retries have been attempted, the error is logged in the results. CSV file as a TCP timeout when a SYN or FIN is sent, and no SYN/ACK or FIN/ACK from the server is received. |

| Case Server Port | The server port where the test case traffic arrives. |
| Client Network | |
| Network MTU | The maximum transmission unit size. |
| Tunnel Mode | Select TCP or UDP. |
| Server Network | |
| Network MTU | The maximum transmission unit size. |
