請教先進~雙WAN備緩的問題

目前的設備為USG 60,

申請2家ISP , A 主要的線,網速較快,有實體IP/NAT給NAS設備服務

B為備緩的線,網速較低.

需求為：A線路如果斷網了, 能讓B線路自動接手. 讓公司內的同仁仍然可以有網路可以用

但NAS等服務暫時沒有用沒有關係. 這樣子的設定雙WAN設定有何文件可以參閱呢?

或是有先進可以指導嗎?

    Hi @Jerry686,

    在CONFIGURATION > Network > Interface > Trunk > User Configuration新增一筆trunk.

    假設wan1是ISP A, mode設定Active.

    wan2是ISP B, mode設定Passive.

    Trunk新增完成後, 在CONFIGURATION > Network > Interface > Trunk > Default WAN Trunk選擇新增的這筆trunk.

    另外, 可以依照需求決定是否要勾選Disconnect Connections Before Falling Back.

    Disconnect Connections Before Falling Back: 當trunk裡的Active interface恢復時, 切斷Passive interface的既有連線.

    在CONFIGURATION > Network > Interface > Ethernet > wan1和wan2, 分別設定Connectivity Check.

    勾選Enable Connectivity Check並勾選Check Default Gateway或Check These Addresses.

    如果選擇Check These Addresses, 請填入一組合適且穩定的外部IP address, 例如: Google public DNS server 8.8.8.8.
