Windows 10: Bind and start transmission-daemon on specific NIC

transmission.bat

@echo off
set IP=""

for /f "tokens=2 delims==" %%F in ('wmic nic where "NetConnectionStatus=2 and AdapterTypeId=0" get  NetConnectionID /format:list') do set interfaceName=%%F
if "%interfaceName%"=="PIA VPN" (

    for /f "tokens=1-6 delims=:. " %%a in ('netsh int ip show address "PIA VPN" ^|find "IP Address"') do set IP=%%c.%%d.%%e.%%f
    if defined IP (
        echo VPN IP check OK: %IP% -- Starting transmission
        "C:\Program Files\Transmission\transmission-daemon.exe" --foreground --config-dir J:\apps\transmission --bind-address-ipv4 %IP%
    ) else (
        echo "VPN IP check FAIL: %IP% -- Exiting script"
    )
) else (
    echo VPN Interface is not connected, current active interface is: %interfaceName% -- Exiting script
)

This script requires that your VPN Adapter is named PIA VPN (modify the script or rename your adapter).

You'll also probably want to modify the path to transmission executable and the transmission config file on row 10.

I know this is 6 years old, but I just came across a need for this exact script, and you saved me tons of time!
