Windows8.1からLinuxのポートの開放確認

PortQryというツールを使う
参考

ダウンロード @ Microsoft

コマンドの例は以下

PortQry.exe -n 192.168.10.5 -r 2718:3141

以下のような結果が返ってくる

TCP port 2718 (unknown service): LISTENING
...
TCP port 3141 (unknown service): FILTERED

(PortQry Test Messageという文字列を送るようだ)。

FILTEREDは開放されていないポート

UDPの確認は以下のようにする 参考

PortQry.exe -n 192.168.10.5 -e 3141 -p UDP

実行結果がUDPの時はLISTENING or FILTEREDになるようだ
参考

If you get a LISTENING or FILTERED response, check and see whether we are checking TCP or UDP, most likely it was attempting to use UDP and this would be a normal response as UDP is connectionless.

追記 2017/12/22

上記のUDP開通確認にて「FILTERED」が表示される場合は、iptablesなどでフィルタされているようだ。
