这个错误促使我调查我的加密参数：
003 "sonicwall" #2: ignoring unknown Vendor ID payload [...]
请一些专家看看并告诉我哪里出了问题？
声波墙（网页界面）：
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
这使我通过了第 1 阶段（密钥交换），但随后它卡在了第 2 阶段（数据交换），在此阶段它循环并报告格式错误的有效负载通知：
