因為ASUS客服說 RT-N12HP虛擬伺服器裡設定 500 1701 4500 UDP 1723 47 TCP，都不會通， 因為VPN port被鎖住，
所以我到分享器 RT-N12HP的虛擬伺服器設定裡，打開 port 443，
然後把群暉 NAS 設為openVPN，用port 443，
然後用一台windows10電腦裝openVPN client，NAS 匯出openVPN設定檔，可是在windows10用openVPN client連接後，還是會出現錯誤如下:
(59.117.130.124是我的對外固定IP)

我也不懂為何port 443已在虛擬伺服器設定了，openVPN卻還是不通?
目前NAS 防火牆關閉，分享器防火牆打開，
我哪裡做錯了?
想請教:
現在如果分享器後面有synology VPN server要透過分享器連外面，那要怎麻辦呢? 請大家教一下該怎樣做?
難道要換一台不鎖VPN port的分享器嗎? 真的要買一台的話，麻煩請推薦一下廠牌型號
