站對站 VPN

我面臨的問題是在 pfSense（版本 2.0.1）和 SonicWall Pro2040 增強版（韌體版本：SonicOS 增強版 4.2.1.4-7e）之間建立網站到網站 VPN。所有配置均已正確完成，但我在 sonicwall 中仍然收到以下錯誤 -

第 1 階段和第 2 階段正確通過，但「有效負載處理」出現問題，我發現這可能是共享金鑰不匹配，但我仔細檢查，兩個防火牆中的共享金鑰都沒有不匹配。它還在 sonicwall 中顯示隧道處於活動狀態

pfSense 的日誌如下 -

IPsec Secondary Gateway Name or Address: 0.0.0.0

Shared Secret: Shared secret for this connection

Local IKE ID:  2.2.2.2 | Select ‘IP Address’ from the drop down menu and then type WAN IP of Sonicwall



Network tab on Sonicwall:

Local Networks

Choose local network from list: 192.168.21.0 | Create an address object for the network or you can use the built in one ‘LAN Subnets’
