我想在 Mikrotik RouterOS 上設定tcpport 8000->的連接埠轉送。192.168.1.16:4200
我做了以下事情：
/ip firewall nat add dstnat chain=dstnat action=dst-nat to-addresses=192.168.1.16 to-ports=4200 protocol=tcp dst-address=<PUBLIC_IP> dst-port=8000
當我嘗試使用來自 Internet 的服務時，以下命令會掛起：
curl <PUBLIC_IP>:8000
我可以看到計數器在 Mikrotik 的 NAT 規則上移動（透過 WebBox）。
在目標機器上，我可以在以下位置看到以下內容netstat -an | grep 4200：
tcp 0 0 0.0.0.0:4200 0.0.0.0:* LISTEN
tcp 0 0 192.168.1.16:4200 <REMOTE_HOST>:37720 SYN_RECV
我確認我可以透過 本地連接到機器curl 192.168.1.16:4200。
我不知道哪裡出了問題:(
更新：防火牆過濾規則：
/ip firewall filter
