+WhatsApp sends audio as **voice notes** (PTT bubble).
+- Best results: OGG/Opus. Clawdbot rewrites `audio/ogg` to `audio/ogg; codecs=opus`.
+- `[[audio_as_voice]]` is ignored for WhatsApp (audio already ships as voice note).

+## Advanced: expose WSL services over LAN (portproxy)
+
+WSL has its own virtual network. If another machine needs to reach a service
+running **inside WSL** (SSH, a local TTS server, or the Gateway), you must
+forward a Windows port to the current WSL IP. The WSL IP changes after restarts,
+so you may need to refresh the forwarding rule.
+
+Example (PowerShell **as Administrator**):
+
+```powershell
+$Distro = "Ubuntu-24.04"
+$ListenPort = 2222
+$TargetPort = 22
+
+$WslIp = (wsl -d $Distro -- hostname -I).Trim().Split(" ")[0]
+if (-not $WslIp) { throw "WSL IP not found." }
+
+netsh interface portproxy add v4tov4 listenaddress=0.0.0.0 listenport=$ListenPort `
+  connectaddress=$WslIp connectport=$TargetPort
+```
+
+Allow the port through Windows Firewall (one-time):
+
+```powershell
+New-NetFirewallRule -DisplayName "WSL SSH $ListenPort" -Direction Inbound `
+  -Protocol TCP -LocalPort $ListenPort -Action Allow
+```
+
+Refresh the portproxy after WSL restarts:
+
+```powershell
+netsh interface portproxy delete v4tov4 listenport=$ListenPort listenaddress=0.0.0.0 | Out-Null
+netsh interface portproxy add v4tov4 listenport=$ListenPort listenaddress=0.0.0.0 `
+  connectaddress=$WslIp connectport=$TargetPort | Out-Null
+```
+
+Notes:
+- SSH from another machine targets the **Windows host IP** (example: `ssh user@windows-host -p 2222`).
+- Remote nodes must point at a **reachable** Gateway URL (not `127.0.0.1`); use
+  `clawdbot status --all` to confirm.
+- Use `listenaddress=0.0.0.0` for LAN access; `127.0.0.1` keeps it local only.
+- If you want this automatic, register a Scheduled Task to run the refresh
+  step at login.
