原本 在公司 由於不可能拿到 High ID, 很難連線 是很正常的
發現 所有 預設port (4662) 的 client 端 都連不上了
很有可能是 被公司網管 給擋掉了
但是 今天 回家 使用實體IP, 拿到了HighID, 又看了一下:

大家注意一下 使用 預設port(4662) 的 仍是連不上!
所以 這個port, 應該是 已經被 ISP 給檔掉了!
如果 還在使用全部預設值的人, 又發現 最進連線狀況不佳,
可以考慮 開始學學 該如何換 port 了!!
建議:
有實體IP的 user, 或是 有 IP分享器密碼的user,
如果 沒有在設計網頁的 可以考慮 換成 port 80 或 443 (這是 Web Service 的預設 port)
或是 port 3128/8080 (這是 知名 Proxy Service 的預設port)
又或者 換成 port 20 (這是 ftp 的預設port)
udp 建議可以換成 port 53 (這是 DNS使用的port)
ISPs 再怎麼檔 這幾個 port 也不可能給你檔掉的!!
如果 上述幾個 port 還是跟您現有環境有衝突
