+    WebVPN works on all platforms but requires an extra step to get to work. On macOS/Linux, `pier.ecn.purdue.edu` can be used as an [SSH jump host](https://www.tecmint.com/access-linux-server-using-a-jump-host/) allowing for development machines to be connected to automatically when openning VS Code.

+    Assuming you already have an SSH key configured for `pier.ecn.purdue.edu`, you can use a jump host by adding the following to `~/.ssh/config`:
+
+    ```
+    Host campb303-pier
+        HostName pier.ecn.purdue.edu
+        User campb303
+
+    Host campb303-w2vm1
+        HostName w2vm1.ecn.purdue.edu
+        ProxyJump campb303-pier
+        User campb303
+        # Forward webqueue2 API Port
+        LocalForward 5000 localhost:5000
+        # Forward webqueue2 API Docs Port
+        LocalForward 8000 localhost:8000
+    ```
