As discussed with Enez the following is observed while performing initial round of testing :
1.In Test step 3 The exported config contains PreUp, PreDown, PostUp, or PostDown sections and it is expected just need to edit the test steps properly.
2. Test steps for Client_full_VPN and VPN as server needs to be mentioned . While adding the details for Client_full_VPN i noticed it is not working as mentioned in the currently available documentation

More from testing progress :
scenario 2: Full-tunnel VPN as Client

• When the AllowedIP's is set as 0.0.0.0/0, ::/0 and in the wireguard UI , the connection when enabled does not stay enabled - hence the ping does not work . No UI error is displayed. Video and logs shared with Enez for debugging .
  From the logs

scenario 3 VPN as server
-Setup all the prequisites with port forwarding in the router settings
-setup Address: 10.10.20.1/32
-ListenPort : 51820 (wireguard is from business-vm) / 51821 (if wireguard is from chrome-vm)
-Binding Network Interface : ethint0
-Routing Scripts: Server
Under Peer
-AllowedIPs : 0.0.0.0/0
-Endpoint : unknown
-PublicKey : from wg1

Try to ping from test server 10.10.20.1 , the ping is not working . The test steps need to be bit more detailed on what needs to be set in the test server wg1 and the wireguard gui in this scenario.

Retested the fix :

1. Error message is shown after entering invalid ip in the Peer allowed IP and trying to enable the Test_connection - fixed

2. New PDF generated for the wireguard contains the corrected information for the Peer allowed IP in scenario 2 (Full-tunnel VPN as client) fixed in the screenshot of the manual - fixed

3.Binding Network interface is corrected to 'ethint0' in the manual- fixed

Errors :

1. When clicked on Generate config ,directly an unknown connection is created without the information fill in screen. Was this intentionally part of the change ? This is bad user experience . Newly introduced.

2. In scenario 2 ( Full-tunnel VPN as client) the bidirectional ping works only when listening port set to 51820 even when Wireguard is initiated from chrome-vm . Listening port in my understanding has to be set for chrome-vm :51821 and business-vm:51820

3. Peer allowed IP needs to be edited in the scenario 3 (VPN as Server) screenshot in the manual to reflect 0.0.0.0/0

4. Still have issues establishing connection with Scenario 3( VPN as server) however Enez is able to successfully connect ,so ruling it as my home router issue as the external server pings to the laptop itself did not work well.

5. Testing instructions in the PR step 2 & 3 should be updated to avoid confusion later: The exported file has PreUp, PreDown, PostUp, or PostDown sections but if you import the file those sections will be cleared.

1. The change was made intentionally.
2. The listening port is only important for "VPN as Server" scenario
3. There is no need to set it to 0.0.0.0/0.
4. It was working for me, but today I couldn't confirm it again. There may be an issue with the testing server. I will check it later.
5. Done
