curlでポートマッピング【UPnP】

Locationを取得する

192.168.10.1はデフォルトゲートウェイ

PowerShell

$client = New-Object System.Net.Sockets.UdpClient
$client.Send([System.Text.Encoding]::UTF8.GetBytes("M-SEARCH*HTTP/1.1`r`nST:upnp:rootdevice"), 37, "192.168.10.1", 1900)
[System.Text.Encoding]::UTF8.GetString($client.Receive([ref][System.Net.IPEndPoint]::New([IPAddress]::Any, 0)))

HTTP/1.1 200 OK
Cache-Control: max-age=120
ST: upnp:rootdevice
USN: uuid:09182736-4554-6372-8191-c025a22a3c84::upnp:rootdevice
EXT:
Server: miniupnpd/1.0 UPnP/1.0
Location: http://192.168.10.1:52869/d030ac11.xml

Linux

echo -e 'M-SEARCH*HTTP/1.1\r\nST:upnp:rootdevice' | nc -u 192.168.10.1 1900

HTTP/1.1 200 OK
Cache-Control: max-age=120
ST: upnp:rootdevice
USN: uuid:09182736-4554-6372-8191-c025a22a3c84::upnp:rootdevice
EXT:
Server: miniupnpd/1.0 UPnP/1.0
Location: http://192.168.10.1:52869/d030ac11.xml

Locationのurlを開いてcontrolURLがエンドポイントになります。控えておいてください

SCPDURLを開くとリクエストのパラメータが分かります

ポートマッピング

192.168.10.100はIPv4アドレス。8000は開放したいポート

curl http://192.168.10.1:52869/upnp/control/f96e0111 \
  -H 'SOAPAction: urn:schemas-upnp-org:service:WANIPConnection:1#AddPortMapping' \
  -d '<?xml version="1.0"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">

  <NewPortMappingDescription>Hoge</NewPortMappingDescription>
  <NewLeaseDuration>0</NewLeaseDuration>
</u:AddPortMapping>
</s:Body>
</s:Envelope>'

コマンド

upnpc -u http://192.168.10.1:52869/d030ac11.xml -a 192.168.10.100 8000 8000 tcp

コマンド

upnpc -u http://192.168.10.1:52869/d030ac11.xml -l

ポートマッピング削除

curl http://192.168.10.1:52869/upnp/control/f96e0111 \
  -H 'SOAPAction: urn:schemas-upnp-org:service:WANIPConnection:1#DeletePortMapping' \

</u:DeletePortMapping>
</s:Body>
</s:Envelope>'

コマンド

upnpc -u http://192.168.10.1:52869/d030ac11.xml -d 8000 tcp

グローバルIP確認

curl -X POST http://192.168.10.1:52869/upnp/control/f96e0111 -H "SOAPACTION: urn:schemas-upnp-org:service:WANIPConnection:1#GetExternalIPAddress"

まとめ

curlでやるとグローバルIPが変わらないので便利です
