exmaple of port numbers in NAT and traceroute

A traceroute is gathered by sending a packet to a target host with a Time To Live increasing by 1 until the destination host is reached.

tracert 不是可以知道從現在的電腦到另外一個IP經過那些router。 可是有工具或者指令可以加上port的嗎？如果說我公司ip是xxx.xxx.xxx.xxx

On Linux systems; traeroute offers -p parameter where port can be specified. The URL I'm trying to hit only works on port 443 and hence beyong certain n/w hop.

Is there a way to traceroute a particular IP and port combination, to see where it is being blocked? Any linux tools / commands / utilities will be appreciated.

本文說明命令列公用程式TRACERT (Trace Route)，此公用程式可用來追蹤「網際網路通訊協定」(IP) 封包傳遞到目的地所經的路徑。 本文討論下列主題：. 如何使用TRACERT 公用 ...

A TCP traceroute run to a domain on a specific port should give a good idea as to where the traffic is being dropped.

traceroute 命令可讓您通過返回封包已遍歷的躍點序列，判斷封包從指定來源到達目的地所行經的路徑。該實用程式隨主機作業系統(例如，Linux或Microsoft(MS) ...

我們可以tracert 到port 53 看看在哪裡被擋住嗎？新的網域控制器在防火牆後面。舊的控制器運作順暢。正在更新核心上的ACL 規則，允許流量進入53 port。
