我正在尝试在 StrongSwan 和 palo alto 之间创建一个隧道。StrongSwan 在 Digital Ocean Droplet（Ubuntu）上运行。在我的 中ipsec.conf，我有：
conn %default
ikelifetime=28800s
keyexchange=ikev1
authby=psk
type=tunnel
conn partner
left=1.2.3.4
leftid=1.2.3.4
leftsubnet=10.17.0.6
leftsourceip=10.17.0.6
right=a.b.c.d
rightid=a.b.c.d
ike=aes256-sha1-modp1024!
esp=aes256-sha1!
conn partner_ip_1
also=partner
rightsourceip=x.y.z.1
rightsubnet=x.y.z.1
auto=start
conn partner_ip_2
also=partner
rightsourceip=x.y.z.2
rightsubnet=x.y.z.2
auto=start
conn partner_ip_3
also=partner
rightsourceip=x.y.z.3
rightsubnet=x.y.z.3
auto=start
conn partner_ip_4
also=partner
rightsourceip=x.y.z.4
rightsubnet=x.y.z.4
auto=start
我可以建立连接，但无法发送/接收任何流量。我的合作伙伴分享了他们的以下配置：
我这边其他一切都是默认的。请问我该如何让它工作？以下是来自ipsec statusall
