这个错误导致我调查我的encryption参数：
003 "sonicwall" #2: ignoring unknown Vendor ID payload [...] 可以请一些专家看看，告诉我什么是错的？
声波墙（networking界面）：
ESP: 3DES/HMAC SHA1 (IKE) IKE phase 1: Enc 3DES, auth SHA1 Ipsec Phase 2: Protocol ESP, Enc 3DES, Auth SHA1 Required XAUTH DH Group 2
/etc/ipsec.conf
ike=3DES-SHA1;modp1024 phase2alg=3DES-SHA1;modp1024
这让我通过第一阶段（密钥交换），但是它在第二阶段（数据交换）卡住，它正在循环，报告格式错误的有效负载通知：
