[操作疑難] Synology site-to-site VPN 成日斷線

本帖最後由 永恆的回憶 於 2021-6-7 00:01 編輯

我用兩個 RT2600ac 將租住單位與工作室用 site-to-site VPN 連起來,
但係唔知點解個 VPN 一用佢嚟傳輸嘅時候,每隔 2-5 分鐘就會斷一次線,而且傳輸速度明顯不正常地慢,搞到成日都用唔到,
已排除係 DDNS 以及 port forwarding 問題 (其中一部唔係直駁 internet,不過已跟足 synology 指示 set port forwarding 500 & 4500。
奇怪在於如果用電腦係租住單位直接用 SSL VPN 連上工作室的 RT2600ac (唔經 site-to-site VPN),就無呢個斷線問題,而且速度可以用盡 bandwidth。
