使用V2R做反向代理内網穿透

環境

内網伺服器Prob1位于内網LAN1,

内網伺服器Prob2位于内網LAN2,

外網伺服器Serv1位于IP 123.123.123.123

内網節點配置

内網節點沒有inbound，隻需要配置一個bridge，一個outbound（以及預設的direct），一對路由規則

配置說明

bridge中的domain，必須要存在于伺服器的portal中，否則會報failed to process reverse connection的錯誤

公網服務節點配置

外網伺服器沒有outbound，對應每個内網節點，要配置一個portal，一對inbound(分别對應bridge和client)和一對路由規則。規則中不需要再設定domain。

在這種規則配置下，對應每一個protal，會有一個專門的inbound連接配接，友善使用者端選擇使用不同的内網。
