Collection of L2TP with IPSec configuration methods

角色

Since I have got my 12.9" iPad Pro with OS 11, I need to configure my RouterOS router to accept VPN connection using L2TP with IPSec configuration. Before having attempted to accomplish this task, I collect a number of websites for making RouterOS to accept the L2TP with IPSec request.

因為IPSec用Public-address認證的關係,

若本地有兩人或更多的透過Router連接L2TP-Server,
在Server端可能會發生後面用戶踢掉前同Public-address用戶(IPSec認證造成的,非L2TP引起)

所以在不更換L2TP連線的情況下,
要讓同Public-address連接Server ,只要不用上IPSec加密即可.

但Windows用L2TP撥號會強制開啟IPSec,
所以下面的步驟即關閉IPSec,用純L2TP進行連線.

1.在電腦桌面下按Windows鍵+R鍵 啟動"運行"視窗,輸入regedit打開註冊表,切換到:

1. HKEY_Local_Machine\System\CurrentControl Set\Services\RasMan\Parameters

複製代碼

2.添加:
鍵值: ProhibitIpSec
資料類型: reg_dword
值: 1
