大家好,

我在大陸的固網(PPPoE 撥上是虛擬 IP,然後自己又過一次 NAY)下接了一隻分機連回台灣的 Elastix 主機

但這隻分機可以成功撥號(SIP 對撥或透過 trunk 撥出去都可以),但其他 SIP 分機沒辦法打給他

請問大家有什麼方向可以協助我 debug 嗎,謝謝XD

轉太多層 是否有對應 問題 是否有VPN 方式可以解決問題....

無法撥入幾乎都是 NAT 關係。兩層 NAT 一定過不了;若是一層 NAT 還要看 防火牆如何設定

感謝樓上兩位

不過我用的 SIP 話機是 GXP1400 不支援 native 的 VPN,且在大陸要過 VPN 有點困難 ( 用筆電播 OpenVPN 有時候都不太會動

我來試試看讓他直接撥 PPPoE 少過一層 NAT 看看好了Orz
