IPSEC 配置 - 寫入套接字時出錯：不允許操作

您好，我正在嘗試第一次設置 IPSEC，但遇到了問題。我認為在第一階段有些問題，但我似乎無法真正弄清楚為什麼我在日誌中有這些：

Feb  2 12:47:59 15[NET] <xxxx|1> sending packet: from ourip[500] to destip[500] (976 bytes)
Feb  2 12:47:59 09[NET] sending packet: from ourip[500] to destip[500]

我不確定如何解決這個問題。不允許操作是否意味著防火牆正在阻止？

我已更改此日誌中的一些敏感數據

有一些防火牆規則禁止寫入套接字。
