阻止端口，以便進程停止使用它進行連接

我想阻止進程連接到端口，我嘗試在下一個示例中使用 ufw，我試圖拒絕到端口 5100 的連接，並且進程 LEOCoin 正在偵聽該端口上的連接

To                         Action      From
--                         ------      ----
22/tcp                     DENY        Anywhere
5100/udp                   DENY        Anywhere
5100/tcp                   DENY        Anywhere
22/tcp (v6)                DENY        Anywhere (v6)
5100/udp (v6)              DENY        Anywhere (v6)
5100/tcp (v6)              DENY        Anywhere (v6)

22/tcp                     ALLOW OUT   Anywhere
5100/tcp                   ALLOW OUT   Anywhere
5100/udp                   DENY OUT    Anywhere
8338                       ALLOW OUT   Anywhere
8338/tcp                   ALLOW OUT   Anywhere
22/tcp (v6)                ALLOW OUT   Anywhere (v6)
5100/tcp (v6)              ALLOW OUT   Anywhere (v6)
5100/udp (v6)              DENY OUT    Anywhere (v6)
8338 (v6)                  ALLOW OUT   Anywhere (v6)
8338/tcp (v6)              ALLOW OUT   Anywhere (v6)

但我無法阻止連線過程。我也嘗試過 iptable，但沒有任何運氣
